Posted By Topic: 3 phase to single phase extension lead

Nov 22 2018 15:14

I want to know if it is legal to have extension lead with a 3-phase plug and a single phase socket.

You could make up something that achieves this and is not electrically unsafe. Obviously you need the N and think of all the other requirements for a lead to be electrically safe.

Slightly off topic, but you may encounter a single phase welder with a 3Ph+N+E plug which is a similar situation (not to be confused with a welder that requires 400V input and is being run off 2 phases)
