I have a question about the validity of advice i recieved today from a B&Q guy who said he was a sparky.
Question. If you had a 2 way light switch and it was wired up for the purpose of being able to switch a light on downstairs by both a switch downstairs and a switch upstairs would it be possible to use T&E at either 1mm2 or 1.5mm2 oppossed to using 3 Core & E as i thought you should between switches.
The guy said that it was normal practice to use the same cable i.e T&E to wire between switches but stated that it must be labelled well as you can get in a pickle.
Can somebody clear this up for me?
