narrowest dual rcd board?

[17thman]

Hi, help would be appreciated

Who can tell me the narrowest, already wired, dual rcd board they have come across, if i have to crimp all the cables to reposition the cu I will but anything below the width of an old wyrlex 8 way would suit. I only need 7 ways in total and 1 for future expansion. It is probably unlikely.

Just quoted a job and met another spark there who, in front of me told the customer that a unsplit single rcd board would have to be used as nothing else would fit!!

I may have to custom build one, but fitting another neutral bar is awkward.

Thanks

17 inches is the narrowest I've come across.

You could use a standard board and use RCBO's instead

You could use single RCD split but you would need RCBo's

mount it sideways <runs and hides>

Two 4 way boards?

Ha Steve, funny you should say that, my friend has one mounted just like that, done any in Yeadon in the past 8 years???

cheers so far, found a wylex 10 way at 340 mil, rcbos is an option but they baulk when they hear the price. 2 4 ways, searching now, thanks lads

No, I'm not a spark lol. Isn't that Rob's stomping ground?

Just being helpful, cheers Steve.

Mmmmm, lets ask him when he returns later..



Yeadon very much his ground.....

 

[Steve]

Ah yes I remember now. He even tagged his place of residence on wikimapia.

But yeadon aint far from him is it. splitting hairs etc

Nope , you could fart at his house, walk to Yeadon and still be repulsed at your own stench!!!!

The standard 8 way Wylex unit is 323mm wide according to the catalogue.

The Wylex NH insulated 13 module unit is 290mm so that would fit in the same space as the old 8 way.

13 modules would be main switch + 2 RCDs taking 6 modules, leaving 7 for MCBs. Wylex ref NHISS3404.

I live in London, and there've been times when I could claim that dubious honour.

I'll post my recipe for sprout curry one day....

If you can get an isolator next to the meter you could have 9 ways in the CU.

Sideways CU, bit of a no-no as the main switch would be side-side operation not up and down, thats why large commercial distribution boards have a seperate space at the bottom for the main switch, preserving the uppy-downy requirement

I normally go the RCBO route in this instance, unless theres a lot of circuits, then its a crimp and move job.
