Hello,

I've reason to call BG tomorrow but thought I'd ask you if you have also had any issues with these. BG Small DB RCDs these two cases are both 40A 30mA ones. The tiny three or four way DBs for use in sheds and garages.

First was a case of a ridiculously high Z from a shed through a small BG DB. That, as we have discussed, turned out to be high impedance through the RCD. That one tripped fine and all was well apart from the time spent doubting my own work.

Today, another Z from a shed on another small BG DB. This one's odd because the RCD trips during a low current L-E test from the outgoing side of the RCD. Once again, I pulled my own work apart. Changed the MCB etc just to be sure.

Today's is an RCD in series with the one in the house.
On an RCD test the one in the house goes first. Not worried about that.

On a Z shed Incoming side, everything is fine and the numbers stack up perfectly.

On a Z shed sockets or lights or without a bus bar at the outgoing side, the shed RCD trips about three seconds into a low current L-E test.

Without it, and with a borrowed RCD from another sub board, all is fine.

So, not a question about the Z tests but a question to ask you if BG are performing for you or if you are experiencing anything similar to these? I'll be calling them tomorrow. 2 out of 2 is enough to send me elsewhere but that means another wholesaler and I'm too lazy to sort that out unless I want Proteus from the local CEF.

Zs

Edit, I should tell you also that under load from today's shed (large circular cutter) everything stays on just fine.

He Zs,

I've fitted maybe a dozen this year and no problems.

My only gripe is the earth and neutral bar screw threads sometimes are a bit graunchy.

I continue to use them as rest of their construction and size seems to be as good/better than most others when taking into consdieration price.

[edit] PS I'd rather eat my Week 4 recycled pants ( correct way, back-to-front, inside-out correct way, inside-out back-to-front) than have to go to CEF, but YMMV ) [/edit]

I've fitted three or four without any problems although I'm usually a metalclad Hager person by choice. I'm disgusted enough with CEF that I'd rather go to B&Q to get bits if I'm desperate. Like the look and attitude of a local YESSS as a new player around here - good stock of Hager and really helpful staff and not bad prices.

Thanks. I don't think it's me so do keep an eye on these ones. Run your tests, don't calculate on BG. I agree on CEF even though we apparently have a new shiny branch near here. Not been there yet.

On BG, yes Stateit, I don't like the quality of the brass either and have had issue in the past with one side of nexus double sockets failing.

I like BG though, good people when you get to meet them and clearly a great deal of loyalty from staff to company which is actually quite refreshing.

I simply don't have time these days for the return visits that failing kit requires. I expect they'll send me a replacement but guess who is going to have to drive 40 mins each way to re fit and then re test and then spend half an hour doing the customer confidence thing?

Shame, I wish it were another brand.

I'll let you know what they say. ( send it back we'll test it and then tell you it was just fine? I'll run it through the play board before I post it back).

I'll let you know what they say.

What are the issues with CEF out of interest. I ve recently started using them in Stroud and they can't do enough for me. on the flip side Denmans have gone down in my ratings big time. Sorry for the thread hijack. I haven't used BG rcd's but have had issues with their pull switches failing in the past in a pretty short timescale.

Wel, my issue is that whoever is serving you decides how much to charge you and that proteus are not very good.

My issue was the purchase of some cable that I do not often purchase. 100m. I thought it expensive so when I got home that day after installing it I enquired elsewhere. it was x 3 other wholesalers.

When I went back to CEF with my findings they cowered. Albeit, I do angry quite well if I choose to and without swearing Rare to need to, but I can.

I'd prefer to be receiving a good price automatically and not falling because of lack of known value at the feet of the guy behind the counter.

That was the reason I stopped using Wilts, they seemed to make the prices up as they went along, especially if you happen to go into a different branch. Denmans have got a bit like it as well even though I have dealt with them for the best part of 20 years. It annoys me that you need to buy so many of one particular item to get a better price when I am spending Ten or fifteen grand a year with them. Its hard to get past a bad experience with someone, I used to try to be loyal to one wholesaler thinking they'd look after me but I'm a bit harder these days and not so embarrassed to ruffle a few feathers when they P me off.

No problem with BG consumer units apart from the grauncy screws in the neutral and earth bars.

Hi , I have wanted to post this for a while but thought I may get into trouble for naming names etc.

The BG plasterboard backboxes with the blue lugs are probably the biggest load of carp that are out there along with the MK gridswitches with the tiny little connections.

I had to install about 80 of the backboxes recently ( supplied by others ) and at least 60 failed when screwing back the accessories.

Never will I use them again.

I should point out that picking up on Stateit's comment about the terminal screws being rough you cannot be confident that using a torque screwdriver that when the torque is reached you have a good connection due to the resistance of the badly machined threads.

Also as Tilley said the blue lugged dry wall boxes aren't worth loading onto your van.

Hello,

Tillie, Me too, blue lugs. I'd not made the connection to a manufacturer. I have a feeling that there's an issue with the brassware.

I made the call a few minutes ago.

On the subject of High Zs through a BG RCD I am assured that they are aware of this and are working on a solution which will bring test results into a similar realm of the better players.

On the tripping RCD from yesterday, a replacement is on the way and they'll have a look at the dodgy one when I send it back to them.

That'll not be for two weeks on account of the state of my diary, but if anything turns up from BG after it has been back to them I'll let you know. I imagine it will just go in the bin though.

Make sure you test them. I'll get a hager one in stock from on line just in case I need it.

Have a nice day y'all

A retired electrician in his late sixties said to me a bit back that it's strange how Hager was the cheap kit at the wholesalers when it was first stocked, now it is their quality brand.

I've just had a reckon up, my opinion is based on installing seven BG consumer units with thirteen RCDs.

I agree totally.

I would rather not do a job at all and do something else instead if i were forced to use CEF.

I cant think of any other funny lines, but im sure the E stands for extortion.

CEF is an acronym for Con Every F****r.

That is a well known phrase for the last 30 odd years where I live!

Evening all,
Have used BG consumer units since B and Q stocked them at good unbeatable price.Have fitted many many 10 way and couple 16 way with no issue apart from the already mentioned terminal screws.Overall a well recommended product from my point of view. But noticed recentley they are creepimg up in price
I donot touch anything else BG as the quality is as bad as CED and MLA ( I shudder every time I think of MLA and dont know how they are still in business)

But, having gone off Wylex and CPN I have recentley been using the Electric centres units which are Schneider and at £45 for 10 way inclusive of 8 breakers has been a good solid and quality buy so far.
Hagar are great but look like they have been in a room with a 120 a day smoker but cant fault the quality.
Regards

I had high hopes for the new schneider domestic units. I couldnt wait to stick one on the wall a few weeks ago, but i have to say i just dont get on with wrap around CU covers (ie the back is totally flat, and the cables exit through a cutout in the front cover where it goes over everything and touches the wall)

Maybe i could get the RCBO's etc and fit them in a proper schneider board of Merlin origin??

Hello Zs,


I used to be a big BG (British General) fan when the company's stuff was made in the U.K. But now, as with so many companies, the stuff is mainly made abroad to a low cost rather than a high quality. Many U.K.names are now living on their past glory, as one wholesaler said to me once. It is becoming increasingly worrying when buying electrical accessories and switchgear to know just how well it is made and how safely and reliably it will perform.

Just what is the solution?

Bye,

Z.

Hello Gary,
my local branch of CEF overcharges and is run by arrogant, ill educated, big headed dimwits that drive posh shiny cars just to insult us working sparks who have to buy there. They are also on some kind of ego trip as well. Denmans used to be O.K. but all the big wholesalers now are owned by a European company I believe and are not U.K. owned any more. Denmans would not serve me once, out of my area, without me providing my name and address and phone number, and grandmothers clothes size etc., even though I was paying cash. The manager muttered something about VAT and being a wholesaler. I could not be bothered to argue. I got the stuff elsewhere as a matter of principle.

Bye,

Z.
