Some differences of lighting distribution board

1、 Under what circumstances is the lighting distribution board regarded as the lighting board?

Answer: for the lighting distribution board, the power supply has five wire system and 4 + 1 form (L1 phase, L2 phase, L3 phase, n zero line and PE grounding wire, such as yjv-4 * 70 + 1 * 35). Only lighting and socket lines can be brought, and lighting board and power board can no longer be brought. (indoor lighting board is three wire system)

2、 How to calculate the distribution board with mixed power and lighting configuration?

Answer: 1. The lighting board dominated by lighting can be equipped with lighting (socket) single-phase line and three-phase power line. The power supply is a five wire system in the form of 4 + 1 (or 5 * 1) (L1 phase, L2 phase, L3 phase, n zero line, PE grounding wire, such as yjv-4 * 70 + 1 * 35; the phase line and zero line are generally thick). The outgoing line of lighting board can be equipped with either lighting board or power board; Calculated as open board.

2. The power board dominated by power can be equipped with three-phase power line and lighting (socket) single-phase line. The power supply is a five wire system in the form of 3 + 2 (L1 phase, L2 phase, L3 phase, n zero line, PE grounding wire, such as yjv-3 * 70 + 2 * 35; the phase line and zero line are not generally thick). The outgoing line of power board can be equipped with power board or lighting board; Calculated by power board.
