Hi Guys, Just done a EICR on a domestic property. Its about 10-15years old so alls good wiring wise. The only observations are that its a 16th edition board so lighting circuits with cables buried in walls less then 50mm not rcd protected. Guessing this would be Code 3? However there is no...

Hi guys, I've been asked to install some down lights in a bathroom. The lighting circuit isn't RCD protected in the consumer unit and there are no spare ways to move it over. (Its the old type of wylex board that won't fit RCBO's in either) Is it ok to put a 2 Way RCD consumer unit in next to...

Thanks for the replies everyone. M4tty thats great thanks! Looks like 10mm will do it then! However think i might go for the 16mm and overkill it. I guess that way the customer can plug what he likes in. Thanks again, very helpful! :-)

The customer has told me the sockets are just for general use and nothing specific so i would imagine no more than 16A.

Hi guys A customer has asked what cable size he would need for an out building in his back garden. In the out building, he's planning on having 3 or 4 general use sockets, 2 lights inside and 6 pillar lights down the garden. The cable length needed to the consumer unit is 85m and will be SWA...

Theres about 30 single phase circuits all together and all have cables buried in walls less than 50mm. Getting on for £600 just for the RCBO's at that. Was thinking 3 x Dual RCD consumer units would be cheaper and can split the circuits across RCDs so not to have 1 x RCD for the lot in a 3Ph...

Hi guys. Is it ok to put 3 x single phase consumer units on a 3 phase supply. One per phase out of each cut out then a henley block connecting the neutrals? Would put a 3 phase board on but theres only single phase circuits and the amount of RCBO's needed would be £££'s. Thanks in advance!

Thanks for the replies! Starting to get my head around it now. I agree when i first opened the enclosure i thought it looks a proper mess! Just to clear a few things up, the bottom horizontal fuse is neutral. One red 2.5mm is a feed to the time clock just above the enclosure and the other coming...

Hi guys Ive just done a EICR at a doctors surgery. Theres a single phase rewireable fuse board for the main circuits (lights, rings etc) and a separate 3 phase board for the electric convector heater radials. This 3Ph board is supplied from another enclosure with a contactor in it (see pic)...

Thanks for the replies! Its a BG s/f/spur and ive used that make for a couple of years with no problems. Will certainly give it a go though. might try an MK one. and failing that put it on a DP switch. Cheers

Hi guys Just been to a job where they had a 2.75-3kW under sink water heater on a plug and socket. The live in the plug had melted. I changed this arrangement for a switched fused spur treating it as if it was a standard immersion heater making sure all connections are tight as i thought this...

steve3948: I see what your saying - you can charge what you want and its up to the customer if they want to pay it or not. My problem is B&Q telling the customer the supplementary bonding has to be done and charging well over the odds for the job not even done properly. You cant expect the...

Hi. Ive just been to a customers house that has asked to have the gas and water bonding done as a previous electrician had said he couldn't sign it off as there was no bonding. I asked what he was signing off and the customer didnt really know. It turns out he had had a new bathroom fitted by...

Hi What would the reference method be for a circuit that runs under a floor upstairs (through and along joists etc) then plastered in the wall in steel capping down to a switch/skt etc? And would it be the same for a circuit in a loft, say placed on top of thermal insulation before dropping...

Hi! Where do I find the different codes for departures from 7671? e.g Wiring that is the old colours (Red/Yellow/Blue) is code 4 - not dangerous etc. Also, I changed a consumer unit for a customer and the only things Ive picked up on the test is that its the old colours as mentioned above, no...

Thanks for the replies! The switch fuse is at the mains. Ive taken it out for the time being so just got the SWA poking out the wall at the minute. The JB is a waterproof enclosure on the edge of the tennis court. Was hoping to just take a supply from the mains to a switch, switch to a...

Hi! Don't know if anyone can help? Im currently doing a part P upgrade on a customers house. He had an old rewirable fuse board that had a 63A switch fuse off it that feeds his tennis court lights. Its wired from the switch fuse to an outside JB in 16mm 3core SWA then 2.5 SWA after that to the...
