- Placement
- Indoor
- Plug-in or 240 V
- 240 V: plugs into a 240 V outlet on a dedicated circuit.
- Circuit
- 240V, 3300 watts, 15 amps, plugs into a 240v 15a outlet, NEMA 6-15P, as the maker publishes it.The maker publishes a 15 amp circuit. Sized from the 3.3 kW heater by the 125 percent continuous load rule, the minimum is 20 amps on 12 AWG copper. NEC 422 gives the rating marked on a listed appliance authority over that calculation, so both figures can be right; your electrician decides which applies to your run.Check it on the calculator.
