Problem with power supply to shower

[cookiemonster]

Hi all, I am having a problem with my shower and was hoping one of you could help.
My old shower developed a leak so I have bought exactly the same model hoping I could just swap them.
Did that earlier today but I have a question about the electric supply which goes into the shower in that the wire is too fat to go into the lego brick thingy inside the shower.
The people who fittet the shower originally got round this by bending some of the strands back so not all of it went in.
My question is simply, is it okay to do this? Seems a bit dodgy to me but what do I know!
And if it isn't, is there a way round it??

No it is not OK to bend the conductors back. All of them must be terminated.

The cable's conductors are sized to carry the maximum current. If some are bent back then it can cause overheating - that may have been the cause of the failure of your original shower?


What make and model is the shower that you have bought/replaced.

Great!

It's a Mira Essentials 8.5Kw jobby.

can't see why you can't get the cable in this shower takes a 10mm cable quite easy.
what size cable are you using ?

The diameter of the cable core is a 5mm circle. The hole in the lego brick thingy is a 4mm x 4mm square.

The diameter of the cable core is a 5mm circle.

If that measurement is fairy accurate, it sounds as if you probably have 16mm² cable, which is unusually (and probably unnecessarily) large for an 8.5 Kw shower feed, and therefore might explain your problem.

Kind Regards, John.

Am I okay to just replace the lego brick thingy with one with a bigger hole?

That's probably what I would do if it were mine (assuming there was adequate space), but since the connector block is presumably part of the shower, by so doing the manufacturer might try to argue that by changing it you had invalidated the warranty.

Kind Regards,John.

Cool, thanks John. There is deffo enough space so I'll do that.
