I agree with Paul. The breaker is really in the circuit to protect the wiring in the wall and prevent fires inside the wall. If the wiring is overloaded with amps then it can burn and the breaker will not trip. In reality the wire becomes the fuse. Not something you want burning inside the wall. 12 ga. is rated for 20 amps. Probably the best thing would be to replace the wiring with 10 ga and use a 30 amp receptacle. That is where I would go with this system. In fact I am getting ready to install some wiring for a collector that I have ordered and this is what I plan to use. 30 amp CB with 10 ga wire. I am getting excited about it. The electric panel for the system came 2 days ago and the filters came today. I am getting ready for it.
