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!

The final arbiter is your building inspector. If he passed it, there's
no code violation. For possible changes, let the building code people
answer the question. From a common sense standpoint if you get rid of
fuses you need some replacement circuit protection which is in the
NEC, just not obvious. Better answers can be found in wiring methods
books that make the NEC legalese less obscure. Good luck.
