Heating element power cable

[MRMARTINSALES]

Hi,

I have just bought a heating element and am really struggling to find a power cable to fit the attached image.

I live in the UK. Does anybody know where I can find one or if there is anything I can do to change the fitting to a more standard fitting.

Thanks

These are designed so that different voltage and current ratings are incompatible, so someone won't plug a 30 Amp load into a 20 Amp circuit. I can't see exactly what the pins look like, but there are a variety of mating plugs available at most US electrical supply stores. If  your plug looks like this:

then the mating plug would be:

If you can find a NEMA designation (the above are L6) then you could be more confident of getting the right mate.
