Obviously you are right. I will ask the customer which he wants, though he doesn't understand the problem and just says "it's working now why change it". Anyway thanks for your input, much appreciated

Hi thanks for the reply. I fully appreciate the worry about two phases. Luckily I have a house with two wings. Each wing on a different phase. I am making sure that no room as both phases in it. My comment about connections at the switch and cable runs was because I was not fully...

Many thanks for the detailed explanation. I have a house with two single phase supplies (off a three phase). On one I have put in a new lighting circuit for upstairs which led me to finding the shared neutral as the downstairs lights gave me a problem on the continuity tests. I have decided...
