Hi mate, great video for trainees like myself. Thanks for taking the effort to film, edit & upload. Very newbie question here, but when you buy the 3core cable does it matter what the core colours are? Obviously you use brown for live but why is it black for CPC & grey for neutral? Can’t you ask for blue, brown & earth? 3phase has black grey brown and it’s confusing me! Cheers 👍🏻
I like Hager and they also have rectangular knockouts. They have a rectangular plastic insert with 20mm knockout so an earthed banjo to earth the armoured should work. Otherwise drill the metal box but hate that as wears me hole saws out ! 🤣
@@letelectricalservices5143 Thanks! Do you need to feed them from none RCD because they have RCD as main switches? So selectivity? Also if that's the case and you wanted to add a none rcd circuit do you just jump everything down 1 at the house CU?
@@jt9473 Do you need to feed them from none RCD because they have RCD as main switches? So selectivity? spot on bud that's why we use SWA. likely it was a 16th edition consumer with RCD one side and none RCD the other side which allowed us to to carry it out this way. We always try us best to meet selectivity and avoid un-wanted tripping on the main CU Hope this help? did you like the video?
Electric showers can have their own mini fuse board same as a garage consumer unit where there is no RCD protection on the main fuse board or there is no more room on RCD side (or room at all) to fit an RCD protected breaker. The main power supply is usually cut into with Henly Blocks to supply the shower board and the 10mm power cable feeding the shower run from that. You need at least a 40amp breaker for any decent electric shower and garage consumer units usually only come with a 32amp and 6amp (sockets and lights) so you have to get a new breaker straight off.
Hi Bill, only effects used on the videos are hyperlaspe to speed it up? No flashes were added to the video not sure which effect you mean sorry, would you be able to give me a time stamp as it doesn't do it on my end
Nice - if you use a piranha nut it’s a bit neater than a banjo and roofing bolt
How does that affect your diversity calculation on db1 . Are you adding two new 32 amp circuits

Was hat thickness is the armoured cabling? 6mm of 10mm.
❤where do you get the power from.

In a shed / garden office does the consumer unit have to be a minimum distance from the floor?
Did you install surge protection on this install?
Did you use a 32A mcb at the house CU?
Yep, it's Run in SWA so no need for RCD protection and also both consumer units have RCD main switches

@@letelectricalservices5143 Thanks just trying to learn more about that stuff as i mainly only do 3 phase industrial work. Yeah it was a good video 👍
Check out my other videos guys!
What size armoured cable did you use?
6mm 3core SWA With a 32amp MCB
@@letelectricalservices5143 Do you need 3 core? Doesn’t the armour act as your bonding?
@@ali3ndnbit does . Try getting 2 core swa from wholesalers.
Can you add an electric shower circuit on a garage consumer unit

Good tools
Why the speed up, no instructions and most missing, cant see what you are doing
Why earth twice this is 3 core armoured
Hi, we earth the armoured aswell to ensure its safe if it was to get hit by a spade or alike
The armour is an exposed conductive part and has to be connected to the earthing system.
Please stop useing that annoying snap/flash effect, it really doesn't do anything for the quality of your
otherwise great video's.
