The only problem with Federal Pacific breakers is with the two ploe
breakers. I have a FPE panel installed in 1962 and all the original
single pole breakers work just fine (I load tested all of them).

I would be interested in how you really do load test your breakers. I have
tested circuit breakers for a lot of years. We call it primary and secondary
injection. Secondary injection is through the ct's. Your using the original
breaker curve published by FPE?
Our current supplies start out at about $15k for an MS-2 and crank well over
$40k for a Doble unit.

How do you test for LD and Instantous?
