can tell the manufacturer has listened to its installers in regards to spacing, screws backed out always saves time on install and the recessed unit gives the client a sleek finish. Especially on new builds with fuseboards being installed at 1350mm, rather than a surface board sticking out the middle of the wall, the recessed could be fitted in the hallway rather than the dreaded under stairs cupboard that us electricians love so much.
Regarding the dual RCD populated board with 63A RCCB's: I know it's up to the installer to match the characteristics of consumer unit to the supply, and that you were just pointing out the features of the unit, but may have been worth a mention that the 63A RCCB's are somewhat on the small side and will probably limit its installation to only those with 60/63A supplies (whether service fuse or consumers switch fuse) - for those who've not seen it, see this BEAMA guidance (of which BG is a member) for details: www.beama.org.uk/resourceLibrary/beama-technical-bulletin---overload-protection-of-an-rccb-or-switch-bs-en-61439-3-ed-2-mar-2019.html Maybe an idea for a short video, with Joe answering the question, what size/rating does an RCCB need to be in a split load board. Looking forward to this weeks lockdown live feed 2 😀
@@efixx good stuff, and it can be linked to Q2.49 of the I&T section, by Electrical Safety 1st (at - www.electricalsafetyfirst.org.uk/professional-resources/wiring-regulations/inspection-testing-certification-and-reporting/ ) as well because under the 18th edition, and BEAMAs interpretation of the relevant regs, many existing installations will be C2 or C3. This could have far reaching consequences, that has certainly got one electrical engineer on the IETs wiring and regulations forum riled up: communities.theiet.org/discussions/viewtopic/1037/26499
@Jules Moules in a normal domestic installation, without heavy continuous loads, it doesn't really matter if the CB total exceeds the upstream fuse value because it's unlikely the fuse will be troubled anyway, particularly a 100A fuse. Note that if method 1 applies, on e.g. a 100A supply, the RCCB does not have to be 100A - it could be 63A if the CB total ratings do not exceed that value, because they cannot overload the RCCB. It's not a problem with RCBOs because there is no RCCB to overload - all you need to do is ensure that for the main switch Inc => In (whether by service or customer switch fuse). PS how did you get the equal to, greater than, symbol to appear as you did (I'm using a mobile)?
@Jules Moules it's 2019, yes, but note that it was to coincide with the 18th ed regs, that came out in 2019. Poor ol' Dave Zawadi seems to be having kittens about it on the IET forum. I doubt he'll get much to change though if there's money in it for BEAMA members who'll now sell bigger more expensive RCCBs both in new boards and installed as retrofits to the many millions of boards that will now be C2s or C3s - if inspectors and installers follow the guidance, that is 😁
I don’t think I’ve fitted a split load rcd board for 8 years, rcbo every time. I like the recessed back box with the brilliant knock out inserts (how long have we been morning about the crappy strip that falls out) Nice😊
Nice video , i have question why all consumer unit in domestic dwelling had two "rcd" and it protects several mcb why not be all breakers "rcbo" and main switch or isolator ... is that debending on cost of work or what . thanks 👍
It is generally down to cost a whole rcbo unit is around twice the price of these split loads of not more than twice, I have rcbo in my home and again in my garage to mainly it is due to cost and preference
Have BG improved the flimsy din rail. I remember using BG and hating the boards for the flimsy din rail when trying to tighten anything up it would just push and bend back
having fitted BG boards before I wasn't impressed with them but with your video I will consider fitting a BG RCBO type A board with SPD with my next job and see how it goes, thank you Gaz
It looks like BG are starting to listen, i like the recess board and the room behind the din rail, not fitted a BG in years as always found the board flimsy and had a few issues with flimsy earth and neutral bars .. i might give one a go again.. after all.. i fit a lot of wylex boards and look at the ahem probs they had years ago
The space for the tails is long overdue in consumer units. Really liking the look of these units. Alot of thought has went into them. Well presented Gaz
FINALLY!! I am going to be able to get my fat fingers on my baby hands in behind the breakers to help me dress my CUs to look as sexy as the ones rapid Gaz has shown in quite a few videos. I am going to go and buy one of these for my own rig while away from college. 💯👊
Good quality board, however, how do split load boards still comply without deviating from BS7671? The failure of 1 circuit should not cause the failure or effect of another circuit?
with the shower board why would the load type affect the r c d surely its risk of D C leakage that affects the r c d, and showers do seem to have more sophisticated control systems these days
Fitted BG in the past, biggest downfall was din rail distortion on larger boards which made fitting the cover difficult. The Garage CU is very well constructed and nice to install 👍. The earth and nuetral bar terminal screwheads can round off if tight to start. But never had to replace any RCD's MCB's through defective manufacturing. Overall a good board for a modest cost.
Having made me watch this 3 times, yes 3 times now, I gotta say I like BG. I know some people are not a fan of them and that's fine, it's a matter of opinion and what works best for them. I really do like the recessed board, just makes it look neater and not so obtrusive. Thanks for the video as always guys 👍
Great consumer unit, but don’t fit one of these if you are fitting it at low level as the lid doesn’t lift up enough to let you see the breakers, not good if your aged customers have to get on their knees to reset an RCD. (I know there is a drop down version but you usually don’t know which you have until you unbox it, and the kid on the drop down version does fold far enough to fit at high level - go figure
I would think you need to look at the building regulations and also look at the surrounding materials to ensure you meet compliance. Most of the time you do not need to, but every installation is different
