What section of the code discusses the allowable # of breakers in a panel? I am questioning the use of a 100 amp, single phase, 30 circuit breaker panel for a residential panel change.

Thank You
 
As of the '08 Code there is no limit beyond what the panel design.
If the manufacturer provides a 100 amp 30 ckt panel and it is suitable for your load, no problem. 408.54 is your Code reference.

Each panel is manufactured differently. A 200 amp panel can be a staright 20 circuit panel 30 cir, or even 40 cir. Some will take twin or tandem breakers and are designed as a 2- or 40 cir, 32-40 cir, etc

I am not sure I have seen 100 amp panels manufactured with 30 circuits. Now you can have a 200 main lug panel fed with a 100 amp circuit and it could have 40 ciruits or whatever the panel is designed for. The calculated load is the important issue here not the number of circuits.

Square D makes a Homeline panel that's 100 amp 30 circuit panel (30 spaces). I haven't purchased one in a few years though, so not sure if it's still around.
 
They also make a 200 Amp panel, with 60 spaces in it.

I had to go to Canada to buy that panel. 60 space, 80 circuit. IT was a value pak, with several single and double pole breakers included.

Total cost: C$308.00 About US$300.00

Plus 13% taxes.
