    3-core (rather than 2-core) SWA requirement for EV chargers...?

    Eh up :) A client (also a friend of mine) bought a new electric car, and it came with "free charger install" by Podpoint. As it's not a simple job getting power from the service head/DB (under the stairs, in the middle of the house, with solid floors) to the detached brick garage (approx 50m of...

    Is 25mm 3 core swa good for earth and Bonding

    So me and a colleague were having a discussion about using 25mm 3 core swa as a live, neutral, earth and a Bonding conductor when relocating the position of the consumer unit, I suggested that using a 25mm 4 core as I can't see the 25mm earth being big enough for 16mm earth and 10mm bonding with...

To get it back going I used some outdoor gland packs and crimped it in a whiska box. It’s due to be replaced apparently but how good would that connection be...

    UK SWA feed to garage for brewing equipment

    Short Version Is it permissible to have 2 feeds to 2 separate consumer units in a detached garage? Is it permissible to run SWA underground through a duct/conduit or must it be direct in ground? What diameter SWA would I require for a 10m run, buried and clipped to wall, feeding 3 x 16a...

I am proposing to screw a flat plate of brass onto the top of the DB and mount the glands through it with their usual locknuts, A brass bolt...

    RCD protection to outbuilding

    Not 100% sure on the requirements for RCD protection of outbuildings. I am going to run 10mm2 SWA, about a 20m Run, to a sub board in the outbuilding, buried in the ground. The main house is on a TN-S, and the outbuilding will have a 32Amp hot tub, a few small fridges, a couple TV's, sockets and...

    Pulling in swa

    Good evening all Got a 200m run of 3 core 10mm swa to install in a trench. Rather than pulling it through a duct, was wondering if anyone has ever pulled the duct over the cable, then dropped in into trench. Duct is 50mm internal diameter flexible type. Might be a non starter, just weighing up...
