How to connect a heated towel rail if 4 wires come out of it?
Hello! I bought a new Terminus electric heated towel rail, I decided to check it and collect a temporary connection through the cord, but I encountered an obstacle: there were 3 wires in the wire to the plug and in the instructions (phase, neutral, ground), and 4 wires protruded from the heated towel rail (white, black, red and twist grounding) ... total one is clearly superfluous, but what to do with it and why it is needed - that’s the question ...
Hello! Indeed, often 3 wires come out of electric heated towel rails. And what does "... twist grounding ..." mean? Does it have a temperature controller? Please send a photo of these wires, maybe we’ll say something, because it’s difficult to give you a normal answer, and tell me what kind of model? Alternatively, you can measure the resistance between the wires, and based on the power, calculate which wires apply voltage according to the formula P (towel rail power) = U² / R
