Shower RCD enclosure options

[gazdkw82]

Need to add an RCD to a shower installation. No options to add in the consumer unit so I'm going to add RCD via an enclosure but I'm struggling to find a nice small enclosure that is of a brand Iv actually heard. Most of them are chint, Europa and other brands....Wylex do a small 3 way ip65 enclosure but comments suggest it's very small inside and I fear terminating 10mm in and out will be a world of pain

Are you going to install this in the shower room?

No, be next to existing CU

No, be next to existing CU

Why an IP65 one?

Sorry if you have already considered this, but can you not get an RCBO to replace the MCB in the existing consumer unit?


If that's not an option and you are adding an RCD in an enclosure next to it, I wouldn't worry at all what make the enclosure is, get what makes the best job but just make sure the RCD unit is a quality brand.

Sorry should have said, the CU is based in what looks like an old house. There's a chance of condensation/moisture

Unfortunately not. It's an old rewireable CU. Shower is fed from henly blocks into a stand alone fused enclosure with a 30A bs3036

In that case replace that whole unit with a shower consumer unit. It will come populated with an RCD main Switch and an MCB. What rating is the Electric Shower?

That's the plan, however like I've said, I'm struggling to find a shower RCD enclosure that is made by a brand I actually know

 

[gazdkw82]

Shower is 8.5kw (37A)

The link I have posted above is a Wylex unit. That will replace the existing standalone 3036 overcurrent & short circuit protection with a new unit incorporating an MCB and also add 30ma RCD protection.

True. But it offers little protection from a cold damp environment

 

[TJ Anderson]

You could go for a 40A MCB then. Check the Zs first though, as you will be making changes to the circuit protection.

A cold and damp house does not mean it needs an IP rated DB. This proposed add on is going next to a 3036 rewirable fuseboard right?
The shower may be the least of their worries.....the place sounds inhabitable lol

Amendment 3 and the 18th edition require metal enclosures.

BG do their 5 way metal shower unit in IP65 but it may be too large for what space you have.
Europa as a budget version are not too bad.
