Hi all. I want to replace my existing Federal Pacific Stab-Lok Load
Center breaker box because the reports that I've heard about it scare
me, and I want to rewire my whole house because the old wiring scares
me. I have a replacement plan in mind, and before I bring in someone
that knows more than I do, I'd like to get as much lined up as
possible.

I plan to install a 100amp breaker into my existing FPE (200 amp
service) box to service a new breaker box (also 200 amp service), then
rewire the house to the new box, and because of other reasons we will
be moving the incoming service to the new box. Note: I say "we" but
in this case "we" means electricians and the electric company as far
as they need to be involved.

Anyway, if anyone is familiar with the FPE Stab-Lok load center, I'd
appreciate some advice about the 100amp breaker. I've found the
NA2100 (Type NA, 2 poles, 100 amp) breakers, but I'm not sure if this
is the one I need for this breaker box or not. My existing breakers
are type NC. Apparently the type NB breakers bolt in ("B" is for
"Bolt" obviously). I have found several of the 30amp or less breakers
as type NC, but anything over that seem to be type NA. I just want to
know if the NA2100 will work in my box...or if you need more
information to make that determination.

Thanks,
Charlie

I'm not exactly understanding why you want to feed the panel from the
existing FPE panel, if you're moving the service to the new panel, unless
this is just for a temporary setup. I wouldn't replace the FPE equipment out
of fear of fire. I would replace it simply because it's garbage. I believe
the difference between the NA and NC is that the NA, possibly because of
it's 100 amp rating stabs into four places on the buss, as opposed to just
two

Let me retract that, it appears that the NA breakers are full sized double
pole, and the NC are half sized double pole. My guess is that they don't
make half sized double pole breakers in the larger sizes, like 100 amp. In
any event the 2/100 NA will fit in the panel in a location where you'd
install four full size single pole breakers, two on each side of the buss

Yes, it's only temporary. Rather than replacing everything at once,
it will let me rewire the different circuits as I can, and would
ensure minimal downtime when it comes time to move the service to the
new box. The old FPE is history after that.

Thanks for the response.

I _believe_ all NA and NC are allowed in any FPE panel that takes one or
the other, but the real answer is on the sticker on the inside of your
panel -- it will list the allowable breakers it accepts.

I'm assuming this is intended simply as a temporary feed to the new
panel? Be sure you use adequately-sized cable to feed it -- don't try
to "get by" w/ something too small just because it's temporary and
short-time expected...
