Shower pump wiring?

[JohnnyG]

Hi,

In our new(ish) house there is a power shower and the pump is installed in the airing cupboard, outside any zones.
It was originally plugged in to a socket (upper ring main) on the landing via a hole drilled in the wall and 13amp fuse protected only.
I was a bit wary about it's installation so changed the socket to a 30a rcd (no other rcd's on our cu at moment) whilst I searched for an installation guide, which I've now found.
The *recommendations* are that it is wired to a dp 3amp isolator and rcd protected.
I've changed the fuse and really want to change the socket to a fcu (with rcd) as this socket isn't used for anything else, except it's on the ring.
Whilst I'm competent at the moment in *basic* installations is there anything here that would require notification of any sort?

Cheers.

What do you mean when you describe a 30A RCD?

Sorry, I meant 13amp http://www.tlc-direct.co.uk/Products/CM4906.html

First post nerves

It's OK.

From what you have posted, I think you have done a good job.

It's not ideal, so you should wait for more advice about how you could best go about making a proper job of it.

As it is, it isn't unsafe, but you should consider getting someone in to put the whole circuit on an RCD or RCBO in your consumer unit. I presume the plug top has a 3A fuse in it? If not then it should have.

An RCD socket outlet and a plug with 3A fuse in will be fine. You could change it to a FCU, but there isn't much point, since you can isolate the pump by removing the plug.

Not notifiable, since it isn't in the bathroom and you are not adding any new circuits.

I have put a 3amp fuse in now which is what I meant by "I've changed the fuse"

The cu will be upgraded in the next few months (not by me I hasten to add, but observed by me) so any issues will hopefully be addressed then but in the meantime I'll be improving anything I can.

Thanks, I thought an fcu might be better as the socket is about 4 inches off the floor and easily 'kickable'.
Is there no problem with the cable being simply passed through the wall and plugged in on the other side?

Not as long as you don't kick it.

As I said above it's not ideal, and when you get your consumer unit replaced you can get rid of your trip hazard. It will then no longer be a problem, so don't put it off.

There is every point - it means he can get rid of that truly disgusting idea of a cable with a plug on it coming out of a hole in the wall....

 

[JohnnyG]

OK, thanks all, I'll probably move it to the other side of the wall and on a fcu when the cu is changed

It doesn't look *that bad* to be honest and at least it's safer than it was

instead of an RCD socket, you could have got an RCD FCU and done away with the plug. "F" means it has a fuse, same standard as a plug so you can put a 3A cartridge in.

and redrill that hole in the wall so the flex comes through the back of the wall box.

you'd have to secure the cable with some clips on the other side tho to prevent it from getting pulled out of the wall.
