How to determine the circuit in a distribution box
Check electrical parameters: First understand the basic electrical parameters of Distribution box so that you can have a general understanding of the capacity and performance of the distribution box. Proper estimation and analysis, based on accurate calculations, are essential when designing and installing a power distribution system in both residential and commercial applications. How to determine the size, installation method and wiring mode of distribution box? (1) Wiring method of distribution box 1) Generally, the incoming line of power distribution box adopts five wire system, that is, a, B and C three-way phase line (the general color is yellow, green and red), one way. It receives power from the main electrical supply and divides it into separate circuits, each.
