Hi, as a newbie to Model Engineering and the forums, I would be grateful for any advice on connecting up an Elliot Grinder. I bought the grinder secondhand online. The motor has a plate showing that it is a single phase 240V motor. The cable contains 4 wires, 1 more than I was expecting. Is the extra wire possibly for a foot switch, or has someone wired it up using phase cable. (Sorry images seem to have rotated when uploaded).
