By what % may a sub-panel be exceeded?
Supposedly, the county electrical inspector approved the 100-amp sub-panel containing three dual-circuit breakers totalling 105 amps.
|15|15||15|20||20|20|

Though additional spaces are available, may I add 20-amp breaker for a two-burner electricooktop?

15s are light and outlet circuits
20 is 20 amp outlets
20|20 is electric baseboard heaters

Thank you.

Counting up the breakers is meaningless. This is NOT an indication of load or anything else.

Go to your main panel and count them up. You'll see what I mean.

Was hoping that is the case. Thank you.
I'll total up the ceiling lights, two ceiling fans, exhaust hood, two baseboard heaters. The two-burner cooktop is 15.41 amps.
