Burnt out pull cord to electric shower

[Sammw123]

Hello everyone,

I have recently had a bathroom refurb in our new house as it had no bathroom fitted before. I have a 8.5kw electric shower that is isolated by a 45 amp pull cord. The shower stopped working so I had an electrician come and have a look and the pull cord wires are completely black and the plastic is melted. It never tripped the main fuse box but it is wired into a 32 amp fuse on the main box and the pull cord is 45amp will this cause it to burn? What other options are there for the burning ??? Any advice is much appreciated thr shower is fitted with a 6mm cable but I'm unsure of the size of the cable that goes from the pull cord to the fuse box...

Thanks in advance

Loose connections at the pull-cord switch.

They have to be really tight, and on stranded cable, I would tighten again after waiting a few minutes.

Hi the electrician said he couldnt see any loose cables to the pull cord and I have just found that the cable going from the pull cord to the fuse box is 4mm if this makes a difference

Loose connection at switch. Quite a regular occurrence due to the effort taken to replace the cover and cable movement causing the loosening.
Edit. 4m could well make a difference, as it's undersized, but a loose connection at the switch may not seem loose if it's welded. Weakest point.

45A pull cords are the work of the devil.

Very common problem with shower switches. Using good quality switches reduces the problem but it never seems to fully go away.

replace with acrabtree or click 50A circular switch. easier to fit and as reliable as a Toyota.

You're right, tel. Started using Crabtree when they were the first to do a 50amp. There was nowt else on the market to touch 'em.

The other thing I find about those pull cords, is that the home owner actually use them to isolate the shower after using said shower.

I mean really.
