Hello:

I am thinking about installing an Intermatic Surge Protector, Model IG1240RC
(which replaces their EG240RC) in my 25 year old circuit breaker box.
The box is a Federal Pacific Electric Model No. is LX112-24.

The Intermatic unit's wiring instructions, and probably the only practical
way, have it connected to each side of the line via a dedicated circuit
breaker for each leg.

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.

So, my question is this:

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.

It would sure solve my problem easily.

What do you think ?

Thanks,
Bob
