    Ring wired doorbells (again!)

    I’m trying to install my Ring doorbell (2nd gen) and I’ve discovered that the transformer feeding my Freidland isn’t producing any power. I suspect that I connected the jumper lead between the wrong wires (thanks to Ring’s really confusing instruction!) so I now need to replace it. I don’t want...

    explanation of using 2.5mm2 T+E for a spur from a ring 32A (ring)

    Why can we use 2.5mm2 for a spur from either the CB or a point on the ring ? Why does this not have to be 4mm2 when using a 32A breaker ?

    Comsumer unit - upstairs/downstairs ring mains

    Hello, I bought a new build and noticed the upstairs MCB is controlling some sockets on the opposite floor, so if I flick the upstairs MCB it's also switching off a socket downstairs (I think it's a spur) in addition to all the ones upstairs Is there anything within 7671 that states this is...

    Shower on 4mm ring final circuit.

    Hi, I've got a customer who wants a 10.5 kW shower installed in his bathroom. As it happens he already has two unused 4mm T&E cables run from the CU cupboard to the loft. I know it's unconventional but is there any reason I can't use these cables to make a dedicated RFC for just the shower...

    Hi, So I ended up with a Ring video wired doorbell instead of a Byron video wired doorbell as B&Q were out of stock (had ordered online) and they gave the Ring one at no extra cost (nice of them). Not what I was after but will have to make and do. I don't really want to fork out and buy the...

    Time Bell Cable Potential Usage Doorbell/Security Camera (USB)

    Hi, I purchased a Time twin strand bell cable with a rating of 12-30V, 2A, low voltage, not for mains use. I wish to use this for installing our new Ring wired doorbell. We don't have an existing doorbell wired setup so it would need to conform to a DIN rail transformer specification of 24Vdc...

    I’m rewiring a bungalow and the owner has asked for a radial for all sockets except the kitchen. But there will be a separate washer and dryer in the circuit. Will a 20A radial be enough?

    Have the rules for ring mains changed over the years?

    I am sure when I qualified for the 16 edition we spoke about how to treat a ring main. I know the majority of the time we just learned how to read the book and how to find needed headings but I am sure we also spoke about ring mains. If a socket has two cables coming into the back box then it is...

    Wiring Ring that has already been bypassed

    Hi folks, cautious DIYer, so just looking to confirm something. I got a wired Ring for our neighbors who have been without a doorbell at all. Seems the previous owners had had some sort of smart doorbell system and took it with them. When I got to the part with the chime box it looks like...
