從外形結構區分，電控柜、配電柜(配電盤)是一類的，電控箱和配電箱是一類的,電控箱和配電箱是六面密封，一般都是掛墻安裝，箱的頂部和下部有敲落孔，便于電線、電纜的出入電控、配電箱。 電控柜、配電柜為五面密封，沒有底部，一般都是落地靠墻安裝。

From the perspective of external structure, the electrical control cabinet and distribution cabinet (distribution panel) are of the same category, while the electrical control box and distribution box are of the same category. The electrical control box and distribution box are sealed on six sides and are generally installed on walls. The top and bottom of the box have tapping holes for easy entry and exit of wires and cables into the electrical control and distribution box. The electrical control cabinet and distribution cabinet are sealed on five sides without a bottom, and are generally installed on the ground against the wall.

配電盤一般為兩面密封，也有三面、四面、五面密封的，配電盤都是落地安裝，但后面不能靠墻，配電盤的后面必須留有操作和維護空間。 配電盤具體幾面密封，訂貨時需要提出要求。比如五個配電盤并排連續安裝，只有個左側需要擋板，第五個右側需要擋板，第二、三、四個左右兩側均敞開。如果一個配電盤獨立安裝使用，左右兩側需要都有擋板。 大部分情況下配電盤后面都是敞開的，根據用戶需要后面也可以有門，既能防塵，又方便操作和維護。

Distribution boards are generally sealed on both sides, as well as three, four, and five sides. Distribution boards are all installed on the ground, but the back cannot be against a wall. There must be space for operation and maintenance behind the distribution board. The specific sealing surfaces of the distribution panel need to be specified when placing an order. For example, if five distribution boards are installed side by side continuously, only the first left side requires a baffle, the fifth right side requires a baffle, and the second, third, and fourth sides are open on both sides. If a distribution panel is installed and used independently, there should be baffles on both sides. In most cases, the back of the distribution panel is open, and there can also be doors at the back according to user needs, which can prevent dust and facilitate operation and maintenance.

從功能角度區分，配電盤、配電柜和配電箱是屬于一類的，電控箱和電控柜是屬于一類的。 一般來說配電盤是將電能分配給下級配電柜、配電箱，或者直接將電能分配給用電設備， 配電柜、配電箱直接將電能分配給用電設備，有時也用配電柜是將電能分配給下級配電箱。電控箱、電控柜是主要用于控制用電設備，同時也兼有將電能分配給用電設備的功能。

From a functional perspective, distribution panels, cabinets, and boxes belong to the same category, while electrical control boxes and cabinets belong to the same category. Generally speaking, a distribution panel distributes electrical energy to lower level distribution cabinets or boxes, or directly distributes electrical energy to electrical equipment. Distribution cabinets and boxes directly distribute electrical energy to electrical equipment. Sometimes, distribution cabinets also distribute electrical energy to lower level distribution boxes. Electric control boxes and cabinets are mainly used to control electrical equipment, and also have the function of distributing electrical energy to electrical equipment.

配電柜、配電箱及配電盤內主要安裝刀開關、刀熔開關、空氣開關、熔斷器、磁力起動器(接觸器)、熱繼電器，有時也會安裝電流互感器、電壓互感器、電流表、電壓表、電度表等，電控箱、電控柜內除了安裝上述電氣元器件之外，還會安裝中間繼電器、時間繼電器、控制按鈕、指示燈、轉換開關及其他功能的開關和控制設備，有的甚將變頻器、PLC、單片機、I/O轉換器件、交直流變壓穩壓器等安裝在電控箱、電控柜里面，個別還會將溫度、壓力、流量的顯示儀表安裝在電控箱、電控柜上面。

Distribution cabinets, distribution boxes, and distribution panels are mainly equipped with knife switches, knife fuse switches, air switches, fuses, magnetic starters (contactors), thermal relays, and sometimes current transformers, voltage transformers, ammeters, voltmeters, kilowatt hour meters, etc. In addition to the above electrical components, intermediate relays, time relays, control buttons, and indicator lights are also installed inside the control boxes and cabinets Conversion switches and other functional switches and control equipment, some even install frequency converters, PLCs, microcontrollers, I/O converters, AC/DC voltage regulators, etc. inside the electrical control box and cabinet, and some even install temperature, pressure, and flow display instruments on the electrical control box and cabinet.
