Fused spur!!!!!!!

This should have its own 10mm supply direct from the fuse board.

 

[ShaunCorbs]

+1 to the above should have a fuse of about 40-45 amps and a 6-10mm cable from the consumer unit

you will have blown 13amp fuse. You will need a qualified guy to sort electrics out mate.

Read the post. He HAS voltage at the terminal block in the shower, and from there on to the PCB.

The others - it's not incorrect to have a 10mm cable into an isolator outside the bathroom. This may be what Ronnie means by "fused spur".

Ronnie, the thermal cutout is item 6 on the diagram. Check continuity across that.

Matchless.plumb,

Are you a qualified plumber and electrician that is charging a customer for this job?

I hope this is a wind up as if not you are going to cause a fire and maybe kill someone with your lack of knowledge.

Regarding the installation, Can you tell us the csa of the T&E cable that is being used? What is the rating of the electric shower? What type/rating MCB is being used to protect the cable? Is it RCD protected.

Did you install the circuit? If so are you aware that this is notifiable to building control and requires a full electrical installation certificate to be completed, do you know how to check the R1+R2, Zs, ZE, PFCC etc?

Mark.

Thank you masood again for your help. Thumbs up !!!

I Thank you all for your help!

I have not installed the electric shower, it was a previous installer, just swapped it over today.

It has a RCD at the main circuit board - assuming goes right up the the master bed room to the fused spur.

From fused spur goes to the electric shower which I have everywhere 240v.
As I read it could be a wrong installation based on 10mm cable I have contacted my friend who is a certified engineer who will find the cause of this problem. Continuity was present masood so everything was working.

I will keep you posted what's the issue after my friend rectified the issue.

Probably just cheap faulty shower!

Everything else is supposition, get a qualified electrician in!

Ask two electricians about showers, cable sizes and protection and you'll get at least 3 different answers. If you need proof have a read of their forum. One locally respected electrician informed me, some years back that a RCD was not required on a shower circuit. My response was, it might not be mandatory, but we'll have one anyway. I've yet to lose a job for erring on the side of safety.

 

[stevetheplumb]

agreed to a point, theres a lot of people out there who say the are electricians till you ask for a ticket. no id cards for them!

 

[stevetheplumb]

a decent qualified electrician will know

 

[markadams]

An RCD is required as additional protection for all appliances contained in a room containing a bath or shower. reg: 701.411.3.3

If cable is not run inside insulating material and the volt drop in within regulations then in theory it could be wired in 6mm T&E but I would always run new electric shower cables in 10mm.

 

[AWheating]

6mm always keeps the frost out the loft space

O P said he had 240V but did not say where he was testing this.

If he was testing L & E he could have, but there could be a loose connection in one of the Neutral connections.
