240VAC Baseboard Heater

240VAC Baseboard Heater

240VAC Baseboard Heater

(OP)
When wiring a 240VAC 1000W baseboard heater, by code, is a double pole thermostat required or is a single pole acceptable?

RE: 240VAC Baseboard Heater

2 pole is required if both wires are 'hot' or phase wires that is ungroudned.

If the 240V is between phase and neutral (grounded) then single pole is acceptable.

RE: 240VAC Baseboard Heater

If the thermostat is not being used as the means of disconnect for the baseboard heated, there is no code requirement to use a two pole one.  Controllers (thermostats) are only required to interrupt the power flow, not disconnect all power to the equipment. See 424.20(B) of the NEC.

Sorry,
   I didn't see that this question is in the IEC area before I posted.  My answer only applies where the National Electrical Code (US) is used.

RE: 240VAC Baseboard Heater

I was thinking in terms of a breaker or disconnect. The last post by resqcapt19 is correct too.
Thanks.
