Installation of 2 new consumer units within an outside Office and Garage| By an Electrician in Poole 

Yep, it's Run in SWA so no need for RCD protection and also both consumer units have RCD main switches

@@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?

@@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 👍

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.

@@letelectricalservices5143 Do you need 3 core? Doesn’t the armour act as your bonding?

@@ali3ndnbit does . Try getting 2 core swa from wholesalers.

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.

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
