Consumer Unit Change and it’s a Lewden Consumer Unit in Disguise with 'A’ Type RCBO’s and an SPD

- On site with one of my learners changing a U.K. consumer unit from Lewden (fuse box) as part of the requirements for the course (not how to). The consumer unit has A type RCBO's and a SPD fitted into it but it isn't made by Lewden...? We see the consumer unit being changed and the all important labels being fitting on completion.

Great video! Very interesting.neat job seeing lack of length on cables👍
Hi, the lad struggled because the cables were so short 👍... but the result was neat. Thanks for watching and commenting. Gaz
The symbol on that consumer unit is from the brand it used to be known as which is 'Control Gear Direct, based in Scotland'. It comes from Denmans, strange that they've put it under their Steeple brand, but haven't changed the symbol.
Thanks for that 👍
Nice video Gaz - Control Gear Direct board?
Great video, and nice job on the CU change. I've been using Lewden CU since January this year and find them pretty good, there are a couple of things that slightly annoy me about them though, how did you find it ?
My wish list to Lewden......
1) The Earth bar could do with being slightly longer, it usually only has two holes marked E so where you have both Gas and water bonds it can mess up your CPC identification, and requires re-lablebling.
2) be nice if they could supply a mixed colour label in the stickers pack that comes with the CU
3) the flappy lid only opens up to 90° so it makes my circuit chart sticker a little akward to read when I stuck inside the flap.
Wow thanks for the detailed comment. Gaz 👍
Great video guys 👍
That board looks quite good I've been looking for a compact CU, that looks just the job.
In Malta, electricity meters come fitted with a 40A double pole MCB (don't know whether it is a B or C curve). It is downstream of a TT servicehead with a 40A fuse. When fitting a Type 2 surge protection device, do you think it would still be necessary to install overcurrent protection for the SPD? Given the 2 OCP devices before CU, I would think that I can safely place the SPD upstream of the double pole MCB in the CU itself. What are your thoughts?
Thanks.
Are the cable entry holes in the rear of the board going to be filled with some kind of fire sealant? Thanks
do you need phone to supplier to de-energize supply cables that go to the main switch ?
Cutout was removed 👍
Hi Gaz, great content as always, Why couldn't the SPD be positioned infront (to the left hand side) of the main switch?
The bottom of the SPD is connected to the earth and not the bus bar hence in this form it’s at the end to the left. Wylex now has an SPD that connects at the bottom to the bus bar which make more sense 👍.
I think you misunderstood, I mean far left in its completed form after you changed sides with the main switch, not bus bar side. 👍

And the health and safety executive’s note in BS7671,
Both ignored yet again, Sod it it’s old so I will change it.
Hey gaz!
Was nobody bothered about the termination of armoured braid to earth?
Also I’m i right in saying that you don’t have to stick that circuit chart sticker on the db as the certificate can provide further information? I know there’s a check box for it on schedule of inspections
Cheers mate wait for reply!
Hi, we like the sticker with the circuit chart information on the board. The QS made all the necessary improvements as we were assessing not teaching on the day Bradley and the video didn’t indicated if the learner had passed the assessment.
Why is the bus bar not insulated?
The bus bar guard is fitted at the end 👍🏻
@@GSHElectrical thanks 👍
QS ?
Qualifying supervisor 👍
Great vid, but you've got to love the regulations sometimes, an the way they are blindly followed.
Front of unit @ 6:26 = RCD sticker that states a "a" device that should be tested six monthly. - Quote Gaz: ""Important that it's tested every six months, or half yearly"
Yet Inside it @ 6:46 = 6 devices, each that state on them "TEST MONTHLY" by the manufacturer.
Dohh !
As it's not a temporary installation, (BS7671:2018 514.12.2 NOTE:) there's no scope to correct the wording on the sticker to reflect the increased testing frequency. Or any way to modify the wording that there are multiple devices that need testing, without being no-compliant to the regulation itself. (Unless you are meant to fit 6 of the stickers, as you could interpret the wording of the regulation in that way ! )
