“你有沒有注意過？醫(yī)院配電室的低壓柜上標著 MNS，工廠車間的常寫 GCK，小區(qū)配電房里多見 GGD—— 這些一串字母的配電柜，到底有啥區(qū)別？為啥不同地方要用不一樣的？其實不用怕術(shù)語，這篇就像‘解密’一樣，用大白話講清 GCS、GCK、MNS、GGD——10分鐘讀完，下次路過配電室，你也能分清里面的柜是哪種。其中錯誤和不足的地方歡迎大家批評指正！”

　　Have you ever noticed? The low-voltage cabinet in the hospital distribution room is labeled MNS, the one in the factory workshop is often written GCK, and GGD is commonly seen in the residential distribution room - what is the difference between these series of letter distribution cabinets? Why do different places need to use different ones? You don't have to worry about professional terminology. This article is like 'decryption', explaining GCS, GCK, MNS, GGD in plain language - read it in 10 minutes, and next time you pass by the distribution room, you can also distinguish which type of cabinet is inside. We welcome everyone to criticize and correct the mistakes and shortcomings! ”

　　一、概括的話有以下幾點：1、GGD是固定柜，GCK、GCS、MNS是抽屜柜。

　　1、 In summary, GGD is a fixed cabinet, while GCK, GCS, and MNS are drawer cabinets.

　　二、固定柜

　　2、 Fixed cabinet

　　1、GGD是固定柜，固定柜是不說模數(shù)的（只有抽屜柜或固定分隔柜用模數(shù)來表示，這個后面再說），GGD交流低壓開關(guān)柜具有機構(gòu)合理，安裝維護方便，防護性能好，分斷能力高等優(yōu)點，內(nèi)部的斷路器、接觸器、繼電器等電氣元件直接固定在柜體框架或安裝板上，缺點是回路少，單元之間不能任意組合且占地面積大，不能與計算機聯(lián)絡(luò)。（以上為光伏GGD并網(wǎng)柜圖片）2、GGD 的 “優(yōu)點”：為啥很多地方愿意用它？沒別的，就是 “實在”—— 便宜、結(jié)實、好修，特別適合 “用電穩(wěn)定、不折騰” 的場景：①便宜省錢：因為是 “固定式”，沒有抽屜那種復(fù)雜的軌道、聯(lián)鎖零件，成本比抽屜柜（比如 GCK）低一半都不止。比如小區(qū)配電房、農(nóng)村小工廠，預(yù)算有限，用 GGD 能省不少錢。②結(jié)實抗造：柜體是用厚鋼板焊的，跟 “鋼架柜” 似的，放配電室里用十年八年都不變形。里面的電線接頭、開關(guān)都是固定的，不像抽屜柜有插拔接觸點，不容易松、不容易壞。③電工好修：不用學(xué)復(fù)雜操作，隨便找個電工師傅都能修。比如開關(guān)跳閘了，打開柜門一看就知道哪兒的問題，拆幾根線、換個零件就行，不用琢磨 “抽屜怎么抽、插頭怎么插”。3、日常維護：①擦灰塵：配電柜容易積灰，半年用干毛刷掃掃里面的灰塵，不然灰塵多了會短路跳閘。②看接頭：打開柜門，看看電線接頭有沒有變色、發(fā)焦（正常是銅色，變色就是發(fā)熱了），發(fā)現(xiàn)了趕緊擰緊螺絲，防止燒起來。③試開關(guān)：偶爾拉一下總開關(guān)、分開關(guān)，看看能不能正常跳閘，別等真出問題了開關(guān)沒反應(yīng)。4、應(yīng)用場景：“用電穩(wěn)定、不常換零件、預(yù)算有限” 的地方，基本都選它，適用于中小型配電室、小型泵站、傳統(tǒng)制造業(yè)車間等對擴容需求低、預(yù)算有限、配電需求簡單的場所。三、抽屜柜

　　1. GGD is a fixed cabinet, and fixed cabinets are not expressed in terms of module (only drawer cabinets or fixed partition cabinets are expressed in module, which will be discussed later). GGD AC low-voltage switchgear has the advantages of reasonable mechanism, easy installation and maintenance, good protection performance, and high breaking capacity. The internal electrical components such as circuit breakers, contactors, relays, etc. are directly fixed on the cabinet frame or installation board. The disadvantage is that there are few circuits, and the units cannot be arbitrarily combined and occupy a large area, which cannot be connected to the computer. 2. Advantages of GGD: Why are many places willing to use it? There's nothing else, it's just "practical" - cheap, sturdy, easy to repair, especially suitable for "stable electricity usage, no hassle" scenarios: ① Cheap and cost-effective: because it's "fixed", there are no complicated tracks or interlocking parts like drawers, and the cost is more than half lower than drawer cabinets (such as GCK). For example, in residential distribution rooms and rural small factories with limited budgets, using GGD can save a lot of money. ② Durable and resistant to construction: The cabinet is welded with thick steel plates, similar to a "steel frame cabinet", and can be used in the distribution room for ten or eight years without deformation. The wire connectors and switches inside are fixed, unlike drawer cabinets with plug-in contact points, which are not easy to loosen or break. ③ Electricians are easy to repair: there is no need to learn complex operations, any electrician can fix it. For example, if the switch trips, you can easily identify the problem by opening the cabinet door. Simply remove a few wires and replace the parts, without worrying about how to pull out the drawer or plug in the plug. 3. Daily maintenance: ① Wipe dust: The distribution cabinet is prone to dust accumulation. Use a dry brush to sweep the dust inside every six months, otherwise too much dust will cause a short circuit and trip. ② Check the connectors: Open the cabinet door and check if the wire connectors have discolored or burnt (normally copper colored, discoloration indicates heating). If found, tighten the screws quickly to prevent them from burning. ③ Test switch: Occasionally pull the main switch and branch switch to see if they can trip normally. Don't wait until there is a problem and the switch doesn't respond. 4. Application scenario: In places with stable electricity consumption, infrequent parts replacement, and limited budget, it is generally chosen. It is suitable for small and medium-sized distribution rooms, small pump stations, traditional manufacturing workshops, and other places with low expansion requirements, limited budget, and simple distribution needs. 3、 Drawer cabinet

　　GCK、GCS、MNS都是抽屜柜。以下為逐步解析1、GCK開關(guān)柜?GCK柜體外形尺寸：寬度：400/600/800/1000/1200mm深度：800/1000mm高度：2200/2300mm

　　GCK, GCS, and MNS are all drawer cabinets. The following is a step-by-step analysis: 1. GCK switchgear? GCK cabinet dimensions: Width: 400/600/800/1000/1200mm Depth: 800/1000mm Height: 2200/230mm

　　一、先搞明白：GCK 到底是個啥？你可以把 GCK 理解成 “帶抽拉抽屜的大型配電箱”—— 就像家里衣柜的抽屜，每個抽屜里都裝著控制電器的 “小零件”（比如控制車間電機、空調(diào)的開關(guān)、保護器）。平時這些抽屜推進去，跟柜子連在一起供電；要是某個抽屜里的零件壞了，不用拆整個柜子、不用斷總電，直接把壞抽屜抽出來，換個好抽屜推進去，幾分鐘就能恢復(fù)供電 —— 這就是它比 “固定死的配電箱”（比如 GGD）方便的地方。

　　1、 First, let me clarify: what exactly is GCK? You can understand GCK as a "large distribution box with pull-out drawers" - just like the drawers in a wardrobe at home, each drawer contains "small parts" that control electrical appliances (such as workshop motors, switches for mall air conditioners, and protectors). Usually, these drawers are pushed in and connected to the cabinet for power supply; If a part in a drawer is damaged, there is no need to dismantle the entire cabinet or cut off the main power supply. Simply pull out the damaged drawer, replace it with a new one, and push it in. Power can be restored in a few minutes - this is where it is more convenient than a "fixed distribution box" (such as GGD).

　　二、GCK 的 “過人之處”：為啥不用固定配電箱，非要選它？①咱們拿 “小工廠生產(chǎn)線” 舉例子，你就懂它的好處了：壞了不用停整條線：比如車間里某個電機的開關(guān)壞了，要是用固定配電箱，得先斷總電、拆接線，修 1 小時生產(chǎn)線就停 1 小時，損失錢；但?GCK 是抽屜式，提前備個好抽屜，抽壞的、插好的，10 分鐘搞定，生產(chǎn)線幾乎不用停。②能 “搭積木” 改大?。阂枪S想加個新電機，不用買新柜子 ——GCK 的柜子是拼起來的，像搭樂高一樣，加個新抽屜、接個電線，就能給新電機供電，不用砸墻挪柜子。三、哪些地方會用 GCK？看這幾個場景就懂不用記復(fù)雜分類，記住 “中等需求、要方便維護” 的地方，基本都選它：①小工廠 / 作坊：比如做家具的工廠、織衣服的紡織廠，有幾臺電機，但不是特別高端的生產(chǎn)線 —— 壞了能快速修，又不用花大價錢買高端柜。② / 酒店：控制空調(diào)、照明、電梯的電箱，比如想在節(jié)假日多加幾盞燈，直接加個抽屜就行，不用大改電路。③小區(qū)配套設(shè)施：比如小區(qū)的水泵房、換熱站，里面的電機控制柜用 GCK，物業(yè)師傅不用太，也能換抽屜修。

　　2、 GCK's' standout feature ': Why not choose a fixed distribution box instead? ① Let's take the "small factory production line" as an example, and you will understand its benefits: if it breaks, you don't have to stop the entire line. For example, if the switch of a certain motor in the workshop is broken, if a fixed distribution box is used, the main power must be disconnected and the wiring must be removed first. After repairing for one hour, the production line will stop for one hour, resulting in a loss of money; But what? GCK is a drawer style, with a pre prepared drawer for both damaged and inserted items. It can be completed in 10 minutes and the production line hardly needs to stop. ② Can 'build blocks' to change size: If the factory wants to add a new motor, there is no need to buy a new cabinet - GCK's cabinet is assembled, just like building Lego, adding a new drawer and connecting wires can power the new motor without having to smash the wall or move the cabinet. 3、 Where will GCK be used? By looking at these scenarios, you can understand that there is no need to remember complex classifications. Remember to choose places with "moderate demand and easy maintenance": ① Small factories/workshops, such as furniture factories or textile factories that weave clothes, have several motors, but not particularly high-end production lines - they can be quickly repaired when they break down without having to spend a lot of money on high-end cabinets. ② Shopping mall/hotel: Control the electrical boxes for air conditioning, lighting, and elevators. For example, if the shopping mall wants to add more lights during holidays, simply add a drawer without making major changes to the circuit. ③ Community supporting facilities: such as the water pump room and heat exchange station in the community, the motor control cabinet inside is made of GCK, and the property manager does not need to be too professional, they can also replace drawers for repair.

　　四、平時怎么維護？跟照顧家里抽屜一樣簡單不用請，電工師傅看一眼就會：①定期拉一拉抽屜：看看抽屜能不能順暢抽拉，有沒有卡住 —— 就像家里抽屜軌道別積灰，不然拉不動。②擦一擦 “接頭”：抽屜后面有銅片（跟柜子通電的地方），時間長了會氧化發(fā)黑，用干布擦一擦，不然接觸不好會發(fā)熱跳閘。③檢查 “鎖”：GCK 有個小設(shè)計 —— 抽屜沒推到底，或者柜門沒關(guān)好，就通不了電，防止觸電。定期試試這個鎖好不好使，別讓它失靈。2、GCS開關(guān)柜

　　4、 How to maintain it normally? It's as simple as taking care of a drawer at home without hiring an expert. An electrician can easily pull the drawer at a glance: ① Regularly pull the drawer to see if it can be pulled smoothly and if it's stuck - just like the drawer track at home, don't accumulate dust, otherwise it won't move. ② Wipe the "connector": There is a copper sheet behind the drawer (where it is connected to the cabinet), which will oxidize and turn black over time. Use a dry cloth to wipe it, otherwise poor contact will cause heating and tripping. ③ Check the 'safety lock': GCK has a small design - if the drawer is not pushed to the bottom or the cabinet door is not closed properly, the power cannot be turned on to prevent electric shock. Try this lock regularly to see if it works, don't let it malfunction. 2. GCS switchgear

　　GCS 和 GCK 都是抽屜式低壓柜（都能抽拉抽屜換零件，不用斷總電），但就像 “同一的中配款和低配款”，核心區(qū)別在 “通用型、耐造度、適用場景” 上，咱們用工廠電工的實際視角，白話講透，選的時候不踩坑：一、直觀的區(qū)別：抽屜能不能 “隨便換”（配件通用性）這是兩者核心的不同，直接關(guān)系到電工后期維護的麻煩程度：GCS 的抽屜：全國 “通用款”就像 AA 電池，不管是南孚、金霸王，只要是 AA 型，都能放進同一個玩具里。GCS 的抽屜是全國統(tǒng)一尺寸（國標規(guī)定），比如你上次用 A 廠家的 GCS 抽屜，這次壞了，隨便買 B 廠家的同規(guī)格抽屜，插進去就能用，不用等原廠家發(fā)貨。電工省心的就是這個 —— 不用攢一堆不同廠家的備用抽屜，備一套通用的就行，緊急修的時候不耽誤事。GCK 的抽屜：“廠家專用款”就像某些的手機充電線，只能用自家的，換個牌子就插不上。GCK 沒有全國統(tǒng)一的抽屜尺寸，每個廠家的抽屜導(dǎo)軌、插頭位置可能不一樣：A 廠的 GCK 抽屜，插不進 B 廠的 GCK 柜里，甚同一廠家不同批次的抽屜都可能有點差別。電工維護時得記著：“這個 GCK 柜是 XX 廠家的，抽屜只能找他們買”，萬一廠家沒貨，就得等好幾天，耽誤生產(chǎn).

　　Both GCS and GCK are drawer type low-voltage cabinets (both can be pulled out to replace parts without disconnecting the main power supply), but just like the "same brand's mid-range and low-end models", the core difference lies in "universal type, durability, and applicable scenarios". Let's use the actual perspective of a factory electrician to explain it in plain language, without stepping on pitfalls when choosing: First, the most intuitive difference: whether the drawer can be "easily replaced" (universal accessories). This is the most essential difference between the two, directly related to the difficulty of electrician maintenance in the later stage: GCS drawer: National "universal type" is like AA batteries, whether it is Nanfu or Jinbawang, as long as it is AA type, it can be put into the same toy. Inside. The drawers of GCS are of a nationally standardized size (according to national standards). For example, if you used a GCS drawer from manufacturer A last time and it broke this time, you can simply buy a drawer of the same specification from manufacturer B and insert it to use it without waiting for the original manufacturer to ship it. The most worry free thing for electricians is this - they don't have to save a bunch of spare drawers from different manufacturers, just have a set of universal ones, so they don't have to worry about emergency repairs. GCK's drawer: "Manufacturer specific" is like some brands of mobile phone charging cables, which can only be used at home and cannot be plugged in by changing brands. GCK does not have a nationally unified drawer size, and the drawer rails and plug positions of each manufacturer may be different: A factory's GCK drawers cannot be inserted into B factory's GCK cabinet, and even drawers from different batches of the same manufacturer may have some differences. Electricians need to remember during maintenance: 'This GCK cabinet belongs to XX manufacturer, so we can only buy drawers from them.' If the manufacturer doesn't have the goods, we will have to wait for several days, which will delay production

　　二、能裝的 “電流大小” 不一樣（適配負載）①簡單說：GCS 能扛更大的電流，適合 “大電機、大負載”；GCK 更適合 “中小電機、小負載”：三、“耐造程度” 不一樣（長期用的穩(wěn)定性）1、比如工廠電壓偶爾波動、電流突然變大（比如電機啟動時），兩者的抗造能力有差別：GCS：“骨架粗、銅排厚”，更耐造GCS 的柜子框架用的是更厚的鋼材（像家里的厚鐵門，不容易變形），里面的送電銅排也更粗，哪怕電壓突然波動，銅排也不容易發(fā)熱燒蝕；抽屜的軌道是金屬耐磨款，用十年抽拉還是順滑，不容易卡。GCK：“簡化設(shè)計”，適合穩(wěn)定小負載GCK 的框架鋼材薄一點，銅排也細一點，更適合電流穩(wěn)定的中小負載（比如照明、小水泵）；要是長期用在電流波動大的地方（比如重型工廠），時間長了銅排可能會氧化發(fā)黑，抽屜軌道也容易積灰卡頓。總結(jié)：一句話分清兩者GCS 是 “抽屜通用、能扛大負載、耐造的中高端款”，適合怕停機、想長期省心的場景；GCK 是 “抽屜專用、適合中小負載、經(jīng)濟實用的基礎(chǔ)款”，適合預(yù)算有限、負載不復(fù)雜的場景。簡單說：要是工廠有大電機、修的時候耽誤不起，選 GCS；要是就幾臺小電機、預(yù)算不多，選 GCK。3、MNS開關(guān)柜(低壓配電柜里的實力擔(dān)當(dāng))

　　2、 The "current size" that can be installed varies (suitable for load) ① Simply put, GCS can withstand larger currents and is suitable for "large motors and loads"; GCK is more suitable for "small and medium-sized motors, small loads": 3. The "durability" is different (stability for long-term use). 1. For example, occasional fluctuations in factory voltage or sudden increases in current (such as when the motor starts) result in differences in their durability: GCS has a "thicker skeleton and thicker copper bars", while the cabinet frame of GCK is made of thicker steel (such as thick iron doors at home, which are not easily deformed), and the power supply copper bars inside are also thicker. Even if the voltage suddenly fluctuates, the copper bars are not easily heated and burned; The drawer track is made of metal wear-resistant material, which can be pulled smoothly after ten years and is not easy to get stuck. GCK: "Simplified design", suitable for stable small loads. The frame steel of GCK is thinner, and the copper bars are also thinner, which is more suitable for small and medium-sized loads with stable current (such as mall lighting and small water pumps); If used for a long time in places with large current fluctuations (such as heavy-duty factories), the copper bars may oxidize and turn black over time, and the drawer tracks are also prone to dust accumulation and jamming. Summary: In one sentence, GCS is a "universal drawer, capable of carrying large loads, and durable mid to high end model", suitable for scenarios where people are afraid of downtime and want long-term peace of mind; GCK is a "drawer specific, suitable for small and medium-sized loads, economical and practical basic model", suitable for scenarios with limited budgets and uncomplicated loads. Simply put, if the factory has large motors and cannot afford to delay repairs, choose GCS; If you only have a few small motors and a limited budget, choose GCK. 3. MNS switchgear (responsible for the strength of low-voltage distribution cabinets)

　　一、可以把 MNS 理解成 “低壓柜里的‘高端定制抽屜柜’”—— 比之前講的 GCK、GCS 更精密、更抗造，比 GGD（固定柜）靈活 N 倍。MNS 就是 “高端不銹鋼抽屜柜”—— 抽屜順滑、零件通用、還帶多重鎖，哪怕天天抽拉也不容易壞，而且裝的東西更多、更整齊。它的核心還是 “抽屜式”：里面的開關(guān)、保護器都裝在抽屜里，壞了不用斷總電，抽走壞抽屜、插進好抽屜，幾分鐘就能恢復(fù)供電 —— 但比 GCK 做得更 “”，比如所有廠家的 MNS 抽屜都能通用，不像 GCK 可能換個就插不上。

　　1、 MNS can be understood as the 'high-end customized drawer cabinet' in low-voltage cabinets - more precise and resistant to manufacturing than GCK and GCS mentioned earlier, and N times more flexible than GGD (fixed cabinet). MNS stands for "High end Stainless Steel Drawer Cabinet" - with smooth drawers, universal parts, and multiple safety locks, it is not easy to break even if pulled every day, and it can hold more and more neatly. Its core is still the "drawer style": the switches and protectors inside are all installed in the drawer, so there is no need to cut off the main power if it is broken. Removing the damaged drawer and inserting it into the good drawer can restore power supply in a few minutes - but it is more "extreme" than GCK, for example, all manufacturers' MNS drawers can be universal, unlike GCK which may not be able to plug it in when changing brands.

　　二、MNS 的 “過人之處”：為啥要花更多錢選它？1、MNS 貴，但貴得有道理 ——?專門解決 “不能斷電、要求高” 的場景，咱們拿幾個例子說：醫(yī)院手術(shù)室不能停電：要是控制手術(shù)設(shè)備的電柜壞了，哪怕停 1 分鐘都可能出大事。MNS 的抽屜換得更快，而且有 “抗電弧” 設(shè)計（就像高壓鍋的防爆閥），哪怕內(nèi)部出故障也不會炸，能保證電一直供著。

　　2、 MNS's' standout feature ': why spend more money choosing it? 1. MNS is expensive, but it makes sense to be so expensive -? To specifically address scenarios where power cannot be cut off and there are high requirements, let's take a few examples: the hospital operating room cannot be powered off: if the electrical cabinet controlling the surgical equipment breaks down, even if it stops for one minute, it may cause a big problem. MNS's drawers change faster and have an "arc resistant" design (similar to the explosion-proof valve of a pressure cooker), which ensures continuous power supply even if there is an internal malfunction.

　　2、數(shù)據(jù)中心服務(wù)器多：一個機房有幾百臺服務(wù)器，每臺都要獨立供電。MNS 的抽屜做得特別緊湊，一個柜子能裝十幾個抽屜（比 GCK 多裝一半），還能實時監(jiān)控每個抽屜的電流 —— 哪個服務(wù)器用電異常，馬上能找到，不用挨個查。

　　2. Multiple servers in the data center: There are hundreds of servers in one data center, each of which requires independent power supply. The drawers of MNS are made particularly compact, with one cabinet able to hold more than ten drawers (half more than GCK), and can also monitor the current of each drawer in real time - any server with abnormal power consumption can be found immediately, without the need to check one by one.

　　3、機場、高鐵站不能出岔子：控制安檢機、顯示屏、空調(diào)的電柜，要是壞了會影響旅客通行。MNS 的零件都是 “抗造款”，比如抽屜軌道用的是金屬耐磨材質(zhì)，用十年都不會卡，而且防塵、防潮（像給柜子加了 “防水罩”），哪怕環(huán)境有點潮也不會壞。簡單說：MNS 就是 “低壓柜里的‘牌’”—— 適合 “斷不起電、壞不起” 的地方，花更多錢買個 “萬無一失”。

　　3. Airports and high-speed railway stations must not have any mishaps: the electrical cabinets that control security screening machines, display screens, and air conditioning, if damaged, will affect passenger passage. The parts of MNS are all "anti manufacturing", for example, the drawer track is made of metal wear-resistant material, which will not get stuck after ten years of use, and is dustproof and moisture-proof (such as adding a "waterproof cover" to the cabinet), even if the environment is a little damp, it will not be damaged. Simply put, MNS is the 'safety label' in low-voltage cabinets - suitable for places where 'power cannot be cut off or broken', spend more money to buy a 'foolproof' one.

　　“高端、重要、不能斷電” 的地方，基本都選 MNS

　　Most places that are high-end, important, and cannot be powered off choose MNS

　　三、平時怎么維護？

　　3、 How to maintain it normally?

　　1、雖然 MNS 高端，但維護不復(fù)雜，電工師傅稍微學(xué)一下就會：定期 “遛一遛” 抽屜：像高端抽屜柜要保養(yǎng)軌道一樣，偶爾抽拉一下 MNS 的抽屜，看看有沒有卡頓，軌道里別積灰（積灰會影響順滑度）。

　　1. Although MNS is high-end, maintenance is not complicated. Electricians can learn it a little: regularly "take a walk" drawers: just like high-end drawer cabinets need to maintain the track, occasionally pull and pull MNS drawers to see if there is any jamming, and do not accumulate dust in the track (dust accumulation can affect smoothness).

　　2、擦一擦 “通電接頭”：抽屜后面的銅片（跟柜子通電的地方），時間長了會氧化發(fā)黑，用干布擦一擦 —— 不然接觸不好會發(fā)熱，影響供電穩(wěn)定。

　　2. Wipe the "power connector": The copper sheet behind the drawer (where it is connected to the cabinet) will oxidize and turn black over time. Use a dry cloth to wipe it - otherwise, poor contact will cause heating and affect power supply stability.

　　3、檢查 “鎖”：MNS 的設(shè)計比 GCK 更嚴，比如抽屜沒推到底、柜門沒關(guān)好，不僅通不了電，還會報警提醒。定期試試這些鎖好不好使，別讓報警功能失靈

　　3. Check the 'safety lock': The safety design of MNS is stricter than GCK, such as drawers not being pushed to the bottom, cabinet doors not being closed properly, not only cannot be powered on, but also alarm reminders. Regularly try these locks to see if they work, and don't let the alarm function malfunction

　　給個 “選柜小口訣”，記不住就看這個：沒錢、簡單、不怕?！鶪GD；中等預(yù)算、小負載、能等配件→GCK；怕停、有大負載、要通用→GCS；不能停、要、不差錢→MNS。

　　Finally, give me a "cabinet selection mnemonic". If you can't remember it, look at this: no money, simple, not afraid of stopping → GGD; Medium budget, low load, energy and other accessories → GCK; Afraid of stopping, under heavy load, requiring universal → GCS; Cannot stop, must be safe, not short of money → MNS.
