Hi there, I’m looking for some 4mm double insulated electrical wire preferably in 3phase colours. I currently work on service lifts and one of the tests we have to do is check the current on each phase when it’s in operation. It’s done using a 415v or 690v plug and socket with single core wires connecting them and a current clamp. I’ve only worked for the company a short time and I’m the first electrically qualified person they’ve employed as most of the work is semi skilled. I’m concerned about the treatment the current test cables get as they’re just thrown around in tool bags. Then they plug them into a circuit for testing before switching it on and just grabbing these wires. If there were any knicks in the insulation there’s a real risk of shock. If I can find double insulated cable it would hopefully give that little bit more protection and the guys would notice more if it was cut. If I can get the bits together I can talk to my boss and spend a few hours making up new test leads hopefully. It’s not something I’ve seen before though. Obviously there’s plenty of 4mm cable out there but it’s 4mm flexible wire we need to keep the phases separated for testing. I’ve had a good hour on google so far using as many different terms I can think of but nothing. Have any of you used something like this before?
