Consumer unit Cable entry advice ??

[MrShine94]

Hi all,
I am installing an additional consumer unit in a garage to supply a pool pump, pool lights and garage sockets. Customer wants cables to be clipped direct. Could I use a 25mm Rubber packed gland at each board for a 10mm T&E? Would rather use trunking but customer does not want.

You can use grommets, bushes, glands with oval inserts, bonding nipples or anything else you feel is appropriate.

Entry is from the top of the consumer unit and is surface mounted. I only have 25mm round rubber pack glands.

Also customer wants outside switch for pool lights. Would I just bring a 1.5mm SWA to switch like my rough drawing illustrates?

Glands with round inserts are not meant for T&E, you should use oval inserts designed for T&E. Why not use side or bottom entry?

If you don't know how to wire a switch then I think you should be asking yourself whether you should be doing the job at all.

I think the top of the CU has to be IP4x rated so you would need a proper gland with ovel insert, or better still enter from below.

Seems I was too slow as davesparkes beat me!

It is not the switch that's the issue. Never installed Pool lights.

Not possble to enter from below has to be from the top.

Something like this might be your answer:

32mm Entry Gland for 10 & 16mm Flat T & E - IP68 LS0H | Wiska (WKP32F1016 / 10106243)

But you just asked how to wire the switch?

Pool lights are just like any other lights as far as switching is concerned, for the rest of the installation of then consult BS7671 for the special location requirements for the lights and transformer and the manufacturers instructions.

What I mean is would the switch just need one 2core SWA to supply the transformer. essentially a feed and a switch wire. P.s I am a house domestic house bashing spark so not installed outside switches for pool lights.

I asked customer to get 25mm rubber packed glans. Guess I won't be able to use them.

If you supply materials then the customer won't provide the wrong thing.

He's is adamant he wants to supply material. I was just hoping the 10 mm T&E would pass through the 25mm round Rubber packed gland and I would just tighten it as much as possible. The cable is temporary until trunking can be fitted.

You might want to consider keeping a stock of glands for various cables, for exactly situations like this, where you need a gland you don't have. E.g. a selection with flat entry grommets for T&E, in various sizes (20, 25, 32mm) as well as round ones. Plus a few SWA glands, of course. Installing or changing a consumer unit, I find you often need an unexpected type or size.

You could space the CU off the wall, and have rear entry (ohh Matron). Hager produce them for their CU's. If I recall, some other manufactures do as well. Or you could manufacturer your own.

Couldn't agree more. Without the ability to make a decision on what cable to use or how to gland into a board you should not he carrying out the job.

Hey guys the man is just trying to expand his skills and asking for advice from the more experienced of us. Let's help him to do that no?

That's fair enough, and we all have plenty to learn, but if you call yourself an electrician then ask advice on wiring a 1g switch, you'd expect some raised eyebrows surely?!!
