    Wired Ring doorbell

    In my husband’s haste to decorate our new house, he removed the old round doorbell chime that must’ve been giving power to the wired Ring doorbell! He buried the wires in the wall and filled the hole. If we get the wires back out would there be a way to reconnect them without having to fit the...

    Underfloor Heating on Ring with 32 amp breaker

    We had our kitchen done a few years ago with underfloor heating. When the kitchen was done, a new CU was fitted and everything’s been OK so I didn’t really check anything. The breakers weren’t labelled which ----ed me off at the time so I labelled them all but forgot to check which circuit the...

    Found one leg of ring main disconnected

    My friend was moving into a new (to him) house and wanted to change a cracked socket, so I went to show him how - straight swap - seems straightforward. I'll call this socket A. There are two sets of twin and earth in the back of the socket (as you'd expect), but one leg was wired into a chock...

    Quick Ring Spotlight pro hardwire question

    Looking at getting their hardwire kit, I'm assuming ok to use 3core cable to a 3pin plug instead of going directly to consumer unit or wiring to back of plug socketas seen in many youtube videos? The latter 2 I'd obviously get an electrician in but I'm capable of wiring a 3pin plug. Thanks

    UK Local RCBO protecting ring final alteration.

    Hi I completed a job recently where a hotel reception had a new desk fitted. The old desk dado was supplied via an RCD spur from the existing ring. This ring is fed from one of the very old Merlin single phase boards which I’ve been told you cannot retrofit Schneider ic60n RCBO’s in. I had to...

    Unbalanced final ring

    I have seen a final ring that had the heavy appliances on one leg (L1). Drawing 19.5 amps in total, one leg (L1) was drawing 82% of the 19.5 amps of current. If the ring went up to 32 amps the 2.5mm cable would in theory be just safe enough under the 27 amp maximum. My question is, if 32 amps...
