Hi
I have a 400V welder which I only use occasionally and I have brought to my home workshop. As with most so called 3 phase welders it only uses L1 and L2 + Earth as transformers at 400V do not need L3 and L1 and L2 don't need a neutral as being out of phase with each other they act as each others 'neutral'.
Our house was formally two houses and a shop. When we converted it a two supplies were combined in the property with one part of the house run from one phase and the rest on another - we have two main fuses, one supply marked as yellow live and the other red live. After conversion we had two spare radials, one for the emersion heaters in each house, one of which provides a 32a supply to may workshop - the other is spare.
So -can I supply a L1 and L2 and earth to my workshop by taking a live from the circuit from each side of the house as they will be out of phase with each other and provide 400V. I will combine them with an earth through a RCB to a '3 phase socket'. Comments gratefully received.
