What are an inside electrician and an outside electrician?

Insider electrician usually refers to a low-voltage electrical appliance operator or repairman. Indoor electrician is responsible for laying, distribution and daily maintenance of indoor wires. The senior electrician is also responsible for the transformer and distribution room.

External electrician:

External electrician refers to an outdoor electrician. Of course, the division of labor is not very clear. Because the electricians outside are the business of the electric power bureau, their work is trained by themselves. The electrician outside is responsible for pole erection, wire erection, line maintenance, fault maintenance and so on.
