Melted shower cable - loose connection?

Hi guys,

Popped round to a friend's tonight whose showers stopped working at the house they just bought…money is tight for them and they know I’m a DIYer so asked for some assistance.

I have suggested the connection might have been loose on the terminal which has caused the melting of the wire. There’s a little slack in the cable so I’ve suggested they cut the wire back to clean copper and refit to a new 45A switch, ensuring the terminals are screwed tight

I’ve suggested that if they smell any melting or the shower trips again that they call in a pro.

Just would like a sanity check that my advice was reasonable.

Thanks
Andy

Go with a decent brand of switch, check cable size against load etc also.

That’s what happens when the cable isn’t tightened up properly
