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.
配电盘一般为两面密封，也有三面、四面、五面密封的，配电盘都是落地安装，但后面不能靠墙，配电盘的后面必须留有操作和维护空间。 配电盘具体几面密封，订货时需要提出要求。比如五个配电盘并排连续安装，只有个左侧需要挡板，第五个右侧需要挡板，第二、三、四个左右两侧均敞开。如果一个配电盘独立安装使用，左右两侧需要都有挡板。 大部分情况下配电盘后面都是敞开的，根据用户需要后面也可以有门，既能防尘，又方便操作和维护。
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.
从功能角度区分，配电盘、配电柜和配电箱是属于一类的，电控箱和电控柜是属于一类的。 一般来说配电盘是将电能分配给下级配电柜、配电箱，或者直接将电能分配给用电设备， 配电柜、配电箱直接将电能分配给用电设备，有时也用配电柜是将电能分配给下级配电箱。电控箱、电控柜是主要用于控制用电设备，同时也兼有将电能分配给用电设备的功能。
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.
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.
