This morning's bit of handy work

[uksparks]

Hi,

Just thought id share my work with you, I did this board change this morning, I was contemplating extending the circuits, but managed to get it all to fit quite well, quite neat considering.

Had to put new bonding in and tails and main earth which was a pain dragging it down through the cavity. I had to pull the main fuse in the end despite having WPD out last week to fit the isolator, I then realized today I couldn't get the earth in without removing the fuse!

Started at 7:45am and finished a 1pm, fully tested, inspected and all paperwork done.

Well done...... wheres the door bell gone lol !!!

 

[not clever]

Tidy enough, well done.

 

[Octopus]

Why did you put one lighting circuit with the sockets?

 

[not clever]

Split the two lighting circuits across the rcd's................at a guess.

 

[uksparks]

Why did you put one lighting circuit with the sockets?

Yes for discrimination etc and all that.

 

[uksparks]

Well done...... wheres the door bell gone lol !!!

Well the customer said get rid of it but thought it was best to leave it tucked inside incase they change their mind as they didn't seem too sure.

 

[uksparks]

I've got another board to do on Friday and another one next week too.

 

[Octopus]

Yes for discrimination etc and all that.

But all the sockets are on one of the RCD's with 1/2 the lights?? So no discrmination then!

 

[uksparks]

Yeah I know, some is better than none. To be honest it needs splitting down, it's a five bed house, it's pretty big too and all on one big ring, think it was 1.3 ohms for r1 on the ring.

 

[telectrix]

only way out would have been to split the rfc into 2 radials ( each on a 20A MCB, of course ). not advised if there's any heavy loads.

its OK but listen sunshine...

stop using MK boards....their dogshyte...

 

[uksparks]

It probably wouldn't be too bigs job to split, but that's a job for another day if he wants it.

I quite like the MK boards, I tend to stick with them as have quite a few spars in the van, maybe Fridays board I'll try hager.

 

[telectrix]

BG or schneider for me. might try a curve from denmans, loads of room above MCBs.

 

[Octopus]

If there's only 1 socket circuit the lights should go on the other rcd. Jmo.

Ive switched to hi integrity boards or RCBO boards now as better more flexible solutions for now and the future!

 

[uksparks]

It always comes down to price though and until RCBOs come down I don't think I can sell hi integrity boards at a price that people really want to pay.

 

[ipf]

I wouldn't let one of them customers, that sit on your shoulder watching you do your job, take any photos.

Decent job..... looked pretty decent originally.

 

[GLENNSPARK]

for what you pay the BG boards are to beat so far....

nice busbar in them as well.....the enclosure is more solid as well......just a better board
Iv heard of some saying they`v had probs with the RCDs.....i never have...and i`v fitted quite a few of em...

 

[polo1]

Ditto that^^^^

I have installed a couple recently leaving the non protected as the spares! The most recent one I left the garage db circuit on an mcb only so the garage/garden circuits wouldn't affect the house

 

[GLENNSPARK]

yep....

considering earthing arrangements of course....

rcbo ?

 

[Octopus]

Yup. Plenty of wet dirty earth in the garden.

 

[GLENNSPARK]

rcbo ?

is he on about hi-integ or split load?

 

[Octopus]

rcbo ?

Didn't the look of the DIY work off db2 so this use of the mcb was agreed with the client!

 

[GLENNSPARK]

oh...

just TT the shed then....

 

[not clever]

It always comes down to price though and until RCBOs come down I don't think I can sell hi integrity boards at a price that people really want to pay.

I use all RCBO boards now, DP single module compact rcbo's at £15.60 inc vat each.

 

[GLENNSPARK]

but if the work coming of DB2 was substandard....then shouldn`t juice it up till its brought into compliance....

 

[ipf]

Thats what I'm thinking.....but don't know the facts.

 

[Octopus]

Yeh right. Client has deep pockets and very short arms. My estimate and cert make the scope of works perfectly clear. Db1

feigning skintness (always a lie) is no excuse ....

and your feeder for DB2?

Surface run. Good ir. R1 + R2 as expected. Zs the same

OK but the point i was really trying to make Murdoch is that you have implied that there are dodgy finals coming off DB2...so you havn`t given it additional protection....which leads me to ask:

any additional/fault protection by means of RCD in the shed?

 

[Knobhead]

So Glenn, would you tell the customer you can’t connect power to their garage DB before or after you’ve started the job?

Before, you loose the job.
After, the customer is liable to shove your regs book where it will need surgically removing.

well i wont leave myself open to any possible `examination` by some `authority` someware...

but i will reduce potentials to a minimum...wherever i can...

Oh, just shove it on an rcbo, that'll show him he has a problem, at least.

One comment, ...why not use a bit of blue heat shrink on those neutral connection ferrules, and also maybe cut the length down a little too. Sorry i just have a pet hate of seeing bare conductors within CU/DBs etc....

 

[davesparks]

You can get yourself a nice 10W schneider enclosure with 6 SPSN single module RCBO's with all appropriate bussbars and blanks for about £120, cheaper than doing it with many brands of SP RCBO and it gives you proper segregation of circuits.

Believe it or not that is how MK supply them,

 

[Engineer54]

Maybe, but i for one certainly wouldn't leave them like that.... Though it seems from other CU upgrade photo's, most are prepared to leave them being oversized and bare, but as i say ..Not I! lol!!
