bathroom. I want to take it out and put in a wall mounted (probubly between the studs type or surface mount?) electric heat wall unit. What is the conversion rate from 3 Amps to wattage? Most of these small bath designed units are rate about 1500 watts. Can I replace the baseboard unit with ...what size wattage unit without compromising my breaker rating (15/30 Amp)?; There are two other 6 amp baseboard heaters on that circuit AND the breaker configuration is a "split unit" set up for 220 for more effecient draw/use. Two 15 amp breakers with their switches "tied/bolted" together so they break simultaineously in overload. Hope I'm making myself clear here. Whatever thoughts would be appreciated.
Yeah, forgot to mention that I just ran all new 12 gauge in there and throughout the house. Thanx for the info.
The 12 AWG wire with the 20 amp breaker (can't be bigger) can only have 16 amps of electric heat. Code requires electric heat to be limited to 80% of the circuit. If you are saying there are already two 6 amp units on the circuit, you cannot add another one (1500watts is over 6 amps). Amps = watt/volts.
I'm not sure why you say 15/30 amp. If you had the 2 6A and the 3A heater on a 15A circuit, that is against code to begin with, since that total is 15, and needs to be limited to 12. You can't have 30A on 12AWG wire. If by chance you are saying 30 because it is a 2-pole 15A breaker, it doesn't work that way. You never have 30A of current, it is 15A at 240V.
