Electric shower wiring wrong?

[shempz]

Hi all,

The PRD went on my Triton electric shower. I opened it up to find out where a replacement would go, and someone mentioned that the wiring was wrong. Could any of you experts out there confirm based on the attached? They said is has live/neutral reversal and it's missing the cable grip.

Yes, the incoming line and neutral are reversed.

Thanks - sorry, I'm very much a novice, but is that potentially dangerous?

Yes it is. Polarity reversal often means switches and protective devices do not interrupt the line (live) conductor.

Red and black coming out the wall. Wrong way round. Should be red to brown and black to blue..

FOR GOODNESS SAKE, MAKE SURE THE POWER IS OFF BEFORE WORKING ON IT!

Don’t fully trust any pull cord isolator. Turn it off at the mains too.

Thanks folks. Before I opened the case, I'd already turned off the shower at the pull cord and flipped the switch on the fusebox.

Glad I did!
