WALL SHOWER STOPPED WORKING

Hi UHM,

Sorry to be a pain...just so I know, should I swap the two red wires around and then swap the two neutral (black wires) or should I just try red first and see what happens and then maybe black.

Regards,

Mark.

Hi Mark,

I can't answer that question as I cannot see where the wires are coming from or going to.

The cable that comes from the consumer unit to the switch should be in the terminals marked either In-Feed or supply

The cable that goes from the switch to the shower unit will either be marked Out or Load.

Can you confirm where the wires go before swapping anything as it could just be a case that the neon indicator is wired into the incorrect terminals.

As UHM says make sure the supply from your DB goes to the feed side of the switch and the other to your shower on the load side. DO not cross them over or swap one without the other. both cores from each cable need to be in the right side of the switch .

yes you have wired the load in the supply terminals you will need to swap all wires over

Thanks to Tim, Sparky and UHM,

Will swap the Live wires over and then change the N wires over.

I have two sets of twin and earth coming down from the attic.

Because of the amount of burnt cable and the amount of cutting and stripping back I had to do, I realised after a bit that I couldn't remember which Red wire was the L In or L out and likewise, I couldn't decide which black wire was the N in or N out.

I will switch live wires as well as switch N wires.

Thanks again.

you need to know which ones are the feed and which ones are the load, you might have the neutrals in the right terminals but the lives in the wrong terminals.Its no good just guessing. Buy yourself a multimeter and verify which cable is which , or get the significant other to watch the cables downstairs while you pull them from above.

the neutral and live from the same cable must both be in the same side of the switch

Thanks sparky and Tim,

Sorry to be a pain over something so trivial.

Regards,

Mark.
