I have a Sibir (Swedish) refrigerator which can be powered by either calor gas or electricity. It's quite old but in excellent condition as I use it for only a few hours each month. I would now like to use it with electricity, and need to fit a plug, but it has two wires, one white and one black. Can anyone tell me which is which please?
Note make sure it's a 120V model. If it's a 240V model things are more involved (you can not just fit a US 240V plug to this if it's a european 240 wired unit).
