According to Robert11 :
The problem I have is that although I have been beating the bushes trying to
find someone who has breakers that will fit this box (tried North American
Switchgear and also Voyten Electric) with no luck. Will keep looking, and
might luck out, but it looks like they are probably really unavailable.
Really don't want to replace the box with a new one.


Federal Pioneer (the Canadian arm of Federal Pacific) still exists, and
the breakers are still being made.

You can mailorder new ones from Canada. Most electrical suppliers,
hardware stores and big box stores in Canada stock 'em.

Google for "Federal Pioneer" - you'll find lots.

I remember from reading the NEC codes a while back that it is a real sin to
have 2 (black) wires going to a single breaker. This was written for two
branch circuits, of course, and that each branch must have its own breaker.

I am wondering if this would also be a no-no if I connected the surge
protector wire to a circuit breaker that is also feeding a branch circuit ?
This seems a bit different than what the code was implying shouldn't be
done, and was wondering if this might be allowable.

This is one of those times where you need to ask the inspector inspecting
your work.
