Hi,
I have a 30 amp subpanel fed by a 10/3 wire.
My electrician told me that the code stipulates that the panel contain
no more than 4 circuits.
Why such a limitation? Why can't I split 30 amps among 40 circuits if I
want to? Doesn't the 30amp breaker protect against overloading?
Thanks!
Aaron

I would question what section of code he's making reference to

Probably the part that says everything must be installed in accordance with
its listing -- and the panel is listed, and labelled, for only four circuits.

I can buy a panel that says 100amp (meaning < 100amps) and has 20 circuits.

As Doug points out, if the panel is listed for 4 circuits max, you wouldn't
be able to exceed that. Yes, you can buy a 20 circuit panel with 100 amp
buss, and even if they'll fit, you aren't allowed to install more than 20
circuits in it
