How to wire the electrical distribution box phase sequence
Connect the phase and neutral wires from the input power supply to the input of the Main MCB. If you use a DP MCB for output load then connect both phase and neutral from the output of the RCCB to the input of the Load. In cases where multiple cables need to be connected parallelly in the same phase; ensuring that the same current goes through all cables is possible by the right phase sequence and the correct arrangement of the cables, given the magnetic field interaction and impedances between the cables. The. Unlike single-phase systems, where power is distributed using two wires (one live and one neutral), 3 phase DB box wiring involves three live wires and a neutral wire. Whether you're an electrician or a DIY enthusiast, this guide will help you understand the basics of home electrical distribution.
