    Copeland crankcase heater question

    Part number : 560-2010-04 this heater comes with assorted compressors and has a tag on it that says 265 volts..

    I don't know anything that has 265 volts...can I use this heater on a 110 volt compressor?
    Let's give nukes a chance.

    Yes- the smaller ones almost always say that. A resistive (I.e heater) load can operate at less voltage but in turn you'll get less in this case half the wattage- heat output.

    Actually it would be 1/4 the wattage.. i always remember that from a test question. With a fixed resistance if you cut the volts in half the watts decrease by quadruple
