The electrical line refers to the line connecting the external equipment, such as
the entrance line of the meter box
the power line connecting the mechanical equipment and the distribution box
the connection line between the electrical equipment.
Because these wires are exposed, it is easy to cause damage to the electrical equipment due to short circuit, grounding, overload, etc., which will seriously endanger personal safety.
Therefore, in the electrical equipment and electrical circuit installation design process, we mustconsider its protective measures.
