Main Breaker Question
I have a Square D entry box, circa 1960, with 200 amp service and 20 amp circuit breakers. But instead of a main breaker, there is a "pull-out" with two large fuses. I want to install a Reliance Controls pre-wired transfer switch. Should be easy enough, right? So all I do is pull out the fuses, just as I would flip a main breaker? No special technique required? No big zaps?? Thanks in advance for your help.
