    I never install ring circuits, the potential for danger is unacceptable

    Yes but the point is people will mess with these things. With a radial or a tree, a disconnected live conductor means whatever is downstream stops working - fault is obvious and it gets checked out. Not the case with a RFC. In my opinion that’s bad design. You have to factor this inevitability...

    A leg gets disconnected, no one is wiser because everything still “works” and the circuit is overloaded

    ... yes, there is something wrong with ring circuits - as I stated in my post. Why would you never ever install a tree circuit?

    I never install ring circuits, the potential for danger is unacceptable

    That is exactly my point. The moment you walk out of the door, someone will mess with that ring circuit in time Ok, so 10% of ring circuits do see more than 20 amps, and then what is the chance that on those ring circuits at some point a conductor will be disconnected? This is what I find...

    Funny that. The RFC is an artefact of materials shortage during WWII, and isn’t really used anywhere else in the world spare a few exceptions. If it were the best method, it would have been taken up elsewhere. I don’t know why so many electricians love the RFC other than it’s familiar

    I never install ring circuits, the potential for danger is unacceptable

    I only ever make tree branches with wago boxes, with never any more than 2 cables in a socket installation box. I always test at each socket outlet anyway so that’s no extra work. I disagree, fault finding on a broken ring circuit with a figure 8 somewhere is worse.

    I never install ring circuits, the potential for danger is unacceptable

    I’d like to know if anyone else here refuses to install ring circuits in domestic premises. For me it’s either a 20a radial / tree circuit with 2.5mm, or a 32 radial / tree circuit with 4.0mm. Frankly I’m tired of finding broken ring circuits on 32a CB’s, as well as mismatches on end to end...

    Steel conduit used as CPC in flat, can’t find bonding, can’t find ring main CPC at C.U

    Pete I see where you’re going with this. Ok so given that those readings are fine, what about the bonding situation?

    Steel conduit used as CPC in flat, can’t find bonding, can’t find ring main CPC at C.U

    I don’t have them to hand, but for the sockets around 0.20 ohms and lights 0.8 ohms (maximum)

    Steel conduit used as CPC in flat, can’t find bonding, can’t find ring main CPC at C.U

    I’ve been asked to add a couple of extra points to the single ring main in a flat. Building fabric is concrete, all of the electrical installation is steel conduit buried in the concrete. I opened the consumer unit and could only see one CPC for a radial socket, as well as the main Earth. No...

    Questions about "price per point" for domestic

    I've been working for a firm for a number of years now with jobs on the side, recently gone full time solo. Everything I've done up until now has been either day rate, or price work. I'm based in Surrey / Middlesex by the way, most of my work is in the areas surrounding Heathrow airport and...

    Went to quote, discovered recent EICR has fabricated results. How to proceed with client?

    I think he just wanted some quotes for the remedial work from different electricians.

    My thinking exactly.

    I'll let the customer know that they can report him if they wish then. I find this sort of thing really frustrating, gives us all a bad name, wastes time, and not only that - there were kids in that flat and they're trusting the guy for a report on safety.
