My PMags are on three-position Honeywell switches with down (off), middle (on), up (mom test). Originally, I was fusing the PMags, but I have seen panels with circuit breakers, instead.
What is the rationale for CBs instead of fuses? What circumstance would warrant pulling a breaker instead of switching the PMag off? I am not planning to use the CBs to test the Pmags during runup, but instead, will use the up switch position.
I'm trying to minimize the number of items on the panel for simplicity, but not at the expense of safety.
