I haven't checked the box out yet, but the wires where I plug in the heater looks to be 14 gage, not 12. It's slightly smaller in diameter than 12. The electrician is supposed to be back in a week to install the grounding rod. I'll bring this subject up when he returns and probably have him replace the 20 amp breaker with a 15 amp one.

Edit: No, he didn't wire the circuits, just replaced the breaker box and breakers. My old one was obsolete and didn't support a seperate ground wire.
