240VAC Baseboard Heater

[stja]

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

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.

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.

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