Hi all. I need help understanding some parts of the NEC as they
pertain to my sevice feed and sub panels.

I had my service loop replaced recently from an old 60 amp service
that fed 2 55 amp sub panels directly from a fused disconnect at the
meter.

The new service loop is 200 amps. The existing feed lines, etc to the
subpanels were kept in place and fed via 55 amp breakers, removing the
old fused disconnect.

The electrician installed a 200 amp breaker panel with main lugs only
(No main breaker). He said something about "As long as there are not
any 100 amp feeds to subpanels, a main breaker is not required".

The electrical inspector passed the install with no problems.

Is this correct?

Also, on my subpanels, there is no "Main" breaker either. They are old
screw-buss fuse panels with lugs only. If I replace them, are they
REQUIRED to have a Main Breaker on the sub-panel?

I have a copy of the NEC, but I'm a little lost on these details.

THANKS!

Your 200a panel is not a lighting and appliance panel since the branch
circuits do not originate there. You are limited to 6 disconnects in
there. It could be for feeders to your fuse panels or you could add a
couple big loads directly to the panel. Just remember total needs to
be six or less. As long as your sub-panels are individually protected
at the feed end they don't need a "main" in the panel.- Hide quoted text -

Thanks for the info. That was very helpful! I hooked my Central Air/
Electric furnace direct to the 200A panel as well as my feeders to the
subs. I'll make sure to keep it at or under 6!
