Thoughs on which board please

uksparks · Jan 4, 2015

Hi,

Got a house, 6 bed detached property, currently totally empty.

TNS
100A Cutout fuse supposedly

Ok, so I have two consumer units which need replacing as the covers will not stay on due to damage and broken casings etc.

The bloke would like them all in one unit, which I have to say would be nice.

I have the following across the two boards.

6x Light Circuits (6A)
1x Smoke Alarms (6A)
1x Boiler (16A)
1x Electric Fire (16A)
1x Cooker (32A)
3x Electric Shower (40A)
6x Ring Finals (32A)

To be honest, the house is heavily loaded in terms of the number of showers etc, I don't really know which way to approach this, he will probably not want to go with RCBO's due to cost, but I could stack a couple of boards.

What are your thoughts?

if you do go for a 3phase board with a conversion kit the owner could always get house upgraded to 3phase in thw future and it would be less work

I think thats a good idea, ill work out the cost for a board and see where it goes.

Hager make lovely domestic kit, so I think you cannot go far wrong there, individual RCBOs would be a better bet though, just saying :biggrin:

I know it doesn't, but you have to admit, its quite a lot of demand should it be used together.

Is it an hmo? If so, there is a higher likelihood of showers being on at the same time, and also a possibility of portable heaters in each bedroom. Unlikely to be a problem if everything looks ok at the moment I would have thought.

They are a meter or so apart and the customer would just like them put together ideally into one unit, its not the covers, the backs are damaged and where the screws locate, the lugs are buggered, the whole board needs renewing.

I see, could use bond-it to repair boards but if the customer wants it changing then the customer gets what they want.
Small metal (lol) 3ph board with links would be the best way forward like others have said.

You could pop one of these in with the link out kit and a load of RCBO's

Hager JK112BG Invicta 3 125 Amp Three Phase Distribution Board. |

So £210 for the board, plus £20 for the link out kit, plus about £50 for the disconnector kit, plus 20x £23 for RCBO's

so you would be looking at approx: £700 for parts, which actually doesn't sound that bad.

You need to shop around !! + the front cover will need to be metal if you install to new regs !!!

The one suggested can be obtained in metal also. Ignore 2nd isolation switch as in your case not required. Also ignore MCB. your looking at about £365 ish

You can install both until the 01/01/16. After then dist boards in dwellings must be made of non combustable material or housed in such.

uksparks · Jan 4, 2015

The nature of Plastic CU's are that they are non combustible....

uksparks · Jan 4, 2015

I just spoke to the customer and said to change the board you are looking at about £700 + Labour, he said yes thats fine, get the parts and do it LOL.

telectrix · Jan 4, 2015

these are non-combustible:

Good man, do the job properly, make sure for that price you do not rip him off, use rcbos and be a decent fella.

I think its (I could be wrong) you can install both until 01/07/2015 as all new designs after that date will need to follow the new regs BYB.

They do make great kit. I think the removable top section that you can cutout the knockouts after you have mounted and then re-fit is genius. You get the feeling it was designed with the installer in mind.

Yeah, don't rock up with 2 x Dual RCD DB's. ££££££££!! lol

davesparks · Jan 4, 2015

Contactum metalclad consumer units go up to 36 ways as standard. The big ones have two rows of of MCBs one above the other.

Personally these days I would be getting SBS's SPSN RCBOs and busbar etc and using them in whatever board.

The Dist board one is the only exception. It is to give the manufacturers time to design replacements.

The manufacturers have know about this for long enough, the key word I said was "design".

You said you can install both up to the 01/07/15. The actual case is you can install both up until 01/01/16.
