Wire colour dilemma.
I just wired a fan controller, the only fitting on the circuit. To the
switch from the CU is a red and black T & E cable. From the controller run neutral and two switched lives via a new bit of 3 core and earth, coloured grey, black and brown. I used the black as neutral and put a bit of blue sleeving on it. I connected it to the black supply neutral wire and didn't put any sleeving on it, because it was already the old neutral colour. This looks odd - did I do wrong? Is there a rule? -- Roger Hayter |

There is no requirement to oversleeve old colours with new colours. BTW the general guidance is to use the grey as neutral when using the new colours. -- Adam |

I was reluctant to use black as switched live, although it wouldn't be unusual with the old colours of course. -- Roger Hayter |
