what happen if i have 2 sources of power 400v ( from two generators each 1500kva) feeding two molded case breakers each 3200A and each breaker feeding its loads and there is a buscoupler 3200A between them and of corse every breaker has its own neutral from its generator, my question what happen if i made the neutral be unity for all distribution board? an earth leakage current flows in neutral or what?
