Hello Friends,
My self RRA would like to know the working pricipal of 4P Breaker in sychronization , as the 3P+N works individually here as hard wire interlocking. but for the 4P breaker the Neutral of all looped breaker are interconnected , then how the system is fullproofed for Neutral.
how the master neutral is coming in to action instead of all the rest breakers in line.
