Isolation & Switching

whjohnson

Given that on Xmas Eve was called out to yet another example of an electric shower isolator burning off it's neutral at the terminal, is it time to cease fitting isolators for the likes of ovens and showers?

Can we not just isolate in the consumer unit instead?

From what I have seen, there isn't an isolator of sufficient quality on today's market which is capable of carrying out it's function without burning out during normal service.

Compliments of the Season to one and all.

    Click do a decent shower pull switch with 2 screws per terminal like the decent ones used to be. The problem i have with them is the cable entry at the back should be a bit bigger so you can slide some slack up and down into the ceiling so not forcing it up and putting stress on the terminal because the cable wont bend (usually 10mm). I have started making it a bit bigger with a multi tool and it works fine so long as the cable doesn't get disturbed by somebody above if it's a roof space.
