Extending ring circuit

[Rpa07]

I ordered a bunch of smaller CSA indent crimps when I did an order with CPC Farnell - it’s nice to have them on board and have used them on numerous occasions. If I’m ever not quite sure of the hold strength of the insulated I’ve stripped the insulation, soldered and sleeved.
You do what you can do so you never go back (and sleep at night!)

Can i drill middle of the joist to feed the cable through? Either side of the water pipe or below?

Yes I'd say fine, but as near the top to bottom centre as possible, I'd also go to one side of the notch rather than directly below it, and if you're just running a single 2.5mm cable keep the hole small, 13mm should be plenty.

2 x 2.5 running through the holes.

Armeg skutch chisel is the dogs b*ollx... Saved my forearms.

Loving my brushless dewalt gear. Powertoolmate go to place for power tools. Cheap as chips.

Lift one of the adjacent boards and drill in that "zone"

what a load of waffle .pen and paper to multiply 300 by .4 FFS. if he' was working in inches, he'd probably need a whole software programme to calculate.

What is the difference between buying an MK double socket from Screwfix than an electrical wholesaler apart from maybe price?

Are we on that old argument... it get's somewhat tiresome the views some hold about Screwfix. There's nothing wrong with buying electrical gear from Screwfix. They have some great deals and as you say... what's the difference between say MK bought at Screwfix or a wholesaler?

 

[Toneyz]

It's a bit of snobbery I think some think it is for builders and DIYers.The only thing I would say is that they only sell a limited line of electrical items compared with the electrical wholesalers.

If you are stuck for a back box, a couple of socket outlets, then they are life savers.

Agree, in fact even when b&q sent me a voucher for 20% off or similar so i went and cleared them out of mk double sockets and light switches, and one or two other bits. Work the same as any other.

Another option would be to pull a leg out of the existing socket and crimp to that under the floor.

Pull a leg from two sockets, ditch the cable, extend the RFC from there no need for crimps, MF JBs just extend the RFC simples really, maybe a bit more work but for a competent electrician a simple and safer job, than crimping cables in back boxes.

Used wago 221 in the back of the backbox rather than junction box under the floor. Easier to access in future.

If they are the standard red/blue/yellow crimps, they are not designed for use on solid conductors and do not provide any guarantee of a good, long lasting connection.

For solid cores you should be using uninsulated indent crimps and then the necessary good quality heatshrink sleeving to insulate them.

For extending rings in back boxes I find the Ideal in-line splices are fantastic...

Repaired this on a shower circuit today - either poor workmanship or poor crimps.
32 amp 60898 RCD protected 6mm T+E supplying a 8.5Kw Triton so no other reason for thermal damage than high resistance joint.

Seems to be some corrosion there.

Definitely green on the copper but I saw no obvious water ingress and this was in a cupboard otherwise of landing.

I once did some work in a Council Maisonette, all the sockets in the hall upstairs were corroded.
The previous tenants had owned a dog.

It was 6 foot up a wooden channel so unless the dog was lying on its back . . . Or. . . Stranger things have happened!
