The electric meter box (small power distribution board) is a device to protect the electric energy meter. There are many kinds, such as transparent electric meter box (small power distribution board) and stainless steel magnetic card electric meter box (small power distribution board). The installation of the meter box (small power distribution board) is very important, especially the installation of the incoming and outgoing lines of the meter box (small power distribution board). Then, what matters should be paid attention to in and out of the meter box (small power distribution board)? Here is a brief introduction.

1、 Rain proof measures shall be taken for incoming and outgoing lines

The installation environment of the meter box (small power distribution board) is diverse, sometimes indoors and sometimes outdoors. For the outdoor installation of the meter box (small power distribution board), rainproof measures are particularly important, especially for the incoming and outgoing lines of the meter box (small power distribution board), rainproof measures are more necessary.

2、 The wiring of the meter in the meter box (small power distribution board) shall meet the requirements

There are corresponding standard requirements for the size of copper wires and circuit wires of each meter wiring. Therefore, when installing the meter box (small power distribution board), the size of relevant wires must be checked and can be installed only after meeting the requirements.

3、 The wires inside the metering box must be insulated and flame retardant. At the same time, the wiring in the metering box adopts trunking wiring. The key is that the incoming line and outgoing line must be separated, and the wiring design should be reasonable.

4、 The creepage distance and electrical separation distance of incoming and outgoing units shall meet the requirements.
