Cheap switches.

Replaced this today, could have burned the place down. Don’t cheap out on switches, just saying.

Shower switch? Go Crabtree or go home imo. Not forgetting to ensure the terminals are done up.

It’s usually down to a poor or loose termination of the supply or load cable.
Stranded cables loosen within their terminals easily if the switch plate is moved around too much.

As it’s the neutral terminals that have burnt, we can probably discount overloading.

Crabtree 50A fit and forget

Why discount overloading because the Neutral burned? Same current through both.

MK & Crabtree, I've never had any issues with.

I don't like skimping on switches & sockets. Not worth it.

i use these good quality and twin screw terminals 50 amp, when making the cables off bring the cables in from the top center making sure you can pull and push them in and out twist the cores with pliers otherwise they will just splay out when screwed in leaving half the strands loose so reducing the current carrying capacity of the cable ive never had one burn out that i have fitted in umpteen years and replaced plenty that others have fitted poorly https://www.superlecdirect.com/6087...CFqBwCf5or79ta27zkl9zLa_AgaScbTkaAlFUEALw_wcB

I had the same with the shower switch at our old house. I noticed it look a bit brown one day, so put my finger on the brown bit…… ouch. One of the wires was physically loose and burned in its hole.

The switch has a face

Switch or the fitting at fault? I have seen a lot of badly wired electrics and even the stuff fitted properly, copper softens over time and heat, it can loosen.

Not a happy face…

I have also twisted cores as shown as an apprentice @brightspark .
Anything looped was also twisted together never remember changing burnt items.
Was told by a sparky it was not done nowadays and not recommended. I will still do as I was taught 70 years ago

The reverse also has a face, and another one on the tongue, and another one hiding in the mouth of the tongue, if you zoom in

@8ob barbeque switch is one made by CLICK.
I'd say it was loose terminations though, always is on those bloody shower switches.

 

[brightspark]

went to a customers house to replace a shower pull switch and asked her where it was . up there where up in front of you .thats a 5 amp pully lad who did it had wired it in 2.5mm in to the cooker supply using strip conectors and left the earth hanging out .she said it was a friends son did it and his grandad was an electrician and charged her 80 quid

 

[dobbslc]

She'd have been better off getting a part P kitchen fitter in to do it

 

[brightspark]

i sometimes get customers giving me cheap sh.ite shower switches to fit 1st thing i say is put it in the bin and il fit the one ive brought and guarantee it for a few years .its harder to fit cheap gear

 

[MetalMonkey]

Click are normally pretty decent, but it could have just been poorly installed or just worked loose.
Stranded is a bugger for coming loose and shower switches are always an a**e
I guarantee any working one you remove you could get at least an extra turn out of the terminals....

I'm surprised no manufacturer has yet cottoned on to making a "MF" shower switch with built in wagos.
Seems like that would be the logical solution.
