    Hi

    Mine heater switch is not working yesterday. I tried to change the new switch yesterday, when I opened it. I found the colour does not match with the UK standard wiring colours. My heater is built after 2006, so it follows Current IEC. And my house is built around 1987, so it follows Pre-2004 IEE

    According to Pre-2004 IEE
    Neutral (N) should be black, but mine is red
    Line (L) should be red, but mine is black

    According to Current IEC
    Neutral (N) should be blue, but mine is brown
    Line (L) should be brown, but mine is blue

    I understand it does look weird if compare the UK standard wiring colours. Anyway, I don’t dare to change it as the switch always working. I followed the previous way to set-up the wiring on the switch. It works. These is the second day, everything working fine.

    Is there anything I need to concern? Or everything should be alright?

    Thanks

    It says DP. That means double pole - both L and N are switched off - so it doesn't really matter that they are the wrong way round.

    If you do decide to change them make sure there is no copper showing - like the red and black are now.

    That blue looks rather black, has it been overheating?

    What is it that looks like Sellotape round the red black and green wires?

    Hi

    This is a storage heater. If I put it the right way, does it mean the heater will store the heat in the morning instead of night?

    Thanks

    There should not be any copper showing. The wires need trimming back.
    Sellotape is not insulating tape. It doesn't insulate anything. Good for wrapping presents and nothing else!
    if you want help on this forum I suggest you keep stupid thoughts like that inside your head.

    Bah, humbug.

    Anyway, which was the joke in there, the sellotape or the reversed wire?
    Both? neither? one of them?
