Section standard in the layout of the electric wire for the house decoration

General cross section of wire for standard

The total section of a set of wires made of insulating sleeves can not exceed 40% of the diameter of the casing according to the regulations, that is to say, 60% of the activity space should be reserved. When the wire is working, it will produce a lot of heat. If the wire space in the casing is not enough and overcrowded, it will reduce the heat dissipation space of the wire, reduce the service life, and it is not convenient for the maintenance and pumping of the wire.
