Rcd Board with round knockouts

[suffolkspark]

Hi all, im having a mare trying to find a board that suits my requirements. Can anybody reccomend a sensibly priced off the shelf solution.

I sinlmply want a 100A 30mA upfront type A rcd.
10 usable ways (no size constraint so can be bigger)
ROUND KNOCKOUTS

So many now seem to have square knockouts and I've got lots of 20mm swa and 20mm conduit to bring in.

Hager either have square ko or no ko in that size. lewden all square knockouts, mk and Eaton seem to be type AC rcds.

Help

Fusebox?

Try axiom. They are good.

The Wylex board I had recently was all round holes on the sides/top/bottom (square on the back).

Do you really want a 30mA up-front? That seems a bit low for 10 circuits (though maybe they are all low-leakage ones).

The Wylex type A RCD one CEF stock is 80A so would have to look if they do it in 100A.

fit some galv trunking on top. SWA gland and conduit into that and tails into DB through square knockouts.

Yes, seems they do:

Wylex WRDS100/2 RCD DP Class A 100A 30mA

Hager with no knock outs sounds perfect as you can drill them where you want.

I think @telectrix solution is really by far the best, as very likely you won't have enough knock-outs of the size you want on one side.

You should be able to get a round knockout Hager one with the suffix "RK" at the end of the product code.

Are the axiom type A rcds? I'll have to check, wylex sounds like best contender, 80A incomer will suffice as it's a submain.

I dont wanna messabout with galv trunking etc just wannataje my nice 20mm items into nice 20mm holes

I have been speaking to hager technical and he didnt mention that, their catalogue is a nightmare

need to check the depth of the box before the lid and if insufficient depth, space the trunking off by 1/8" or so.

It's all on show so want it to look good. Just looking for that on the shelf item that should exist

It is 85mm from the panel it is fixed to, up to the edge of the lid. So up to 75mm truncking should be fine.

plenty room here for 20mm holes. easy drill as well:

@pc1966

The wylex NMRS1106L looks spot on, I use wylex 3 phase stuff so would be good to move to 1 brand, but I cant see if it's a type A rcd anywhere,

 

[pc1966]

The Wylex pages are not terribly great either. Here is the consumer catalogue:

https://www.wylexreasons.co.uk/Content/pdf/Wylex%20DCP%20catalogue%20Feb%202018.pdf

It is dated Fed 2018 but seems to be the most current. Page 31 lists the RCDs they do, and they do both, but I don't know what type is in the pre-assembled board but one picture of it on-line shows the AC sort.

To specifically get that you might need to order a 13-way enclosure NM13ED6 separately from the RCD incomer like WRDS80/2 or WRDS100/2

Actually a quick look on the CEF site shows the NMRS1106LA which has the type A RCD included!

It is not listed in the PDF catalogue (Doh!) but is listed on the main company group web site:

Perfect! Cheers I use discount electrical from time to time there good, my wholesalers both have poor stock of boards at the mo

The description is not great though:

The Wylex NMRS1106LA all metal consumer unit is fully compliant with Amendment 3 to BS 7671:2008. Supplied with 100A 30mA RCD isolator. The consumer unit can be populated with up to 11 RCBOs. The NMRS1106LA allows for total isolation of circuits and is the best choice to achieve an 18th edition installation and avoid nuisance tripping

A 30mA incomer is not going to be selective in any way with RCBO!

Hopefully lets you get the job done soon!
