Hey Guys, I’m wiring a Bosch electric tankless water heater at my cabin and I’m not sure which double pole breakers to buy. This is what it calls for:
2 x 240V AC
Amperage 2 x 40 A
Maximum output 17.25 kW
It’s a Homeline main panel, do I get two double pole breakers that are ganged 20amp breakers or two ganged 40 amp breakers?
Are the 40 amp double poles actually 20 amps on each hot leg?
