Main Breaker Question

Posted by bshanley (My Page) on

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.

RE: Main Breaker Question

Turning off all the breakers after the fuse block will put no load on the fuse block when it is removed.

They are normally designed to be rotated 180 degrees and re-inserted to cover the contacts.

'ON' and 'OFF' are on each end of the block to indicate the connection when the block is installed.

Thank you, Brickeye.
