    240v wall heater on single pole switch
    Hello,
    The wall heater is on a 240v circuit. On the heater itself it has a on/off siwtch. But someone wanted a wall switch in another room to control the switch. Is it okay to use a single pole switch to switch one of the hot legs of the heater?

    Thanks in advance

    The better solution would be a (what is popular called) HOTEL switch : one switch contact and two switch-over contacts.
    Disconnect the neutral heater wire (this contact goes to one switch. The neutral goes to the new switch.
    The original switch has to be replaced with a similar hotel switch.
    The switch over contacts of each switch are than interconnected (pull therefore one extra wire from the heater socket to the original switch.
    The new switch requires three wires : one wire to neutral, two wires to the original switch switch-over contacts.

    See the drawing which was made for a light circuit.

    Succes !

    :)

    Thanks Credendovidis,
    But there is no neutral wire to the wall heater, just 2 hot wires.

    Credendovidis, you STILL seem to forget you are not in the US. YES, this IS a US based site unless otherwise stated.

    Here 240v DOES NOT have a neutral.
    Also, for 120v we DO NOT switch neutrals here. This is a DANGEROUS practice and should NOT be suggested.



    Loupi, it is fine to switch a residential electric 240v heater using only one leg. This is a control, not a disconnect, so it is fine.
