Fair point. :) Ok, I'll go ahead and reuse some of the 4mm² or 10mm² T&E that I've got left over from ripping out the previous bodge-job wiring. Thanks again for your help.

Ah ok, thanks for clarifying. Just one final thing, if that's ok.... when it comes to connecting the oven(s) would you specifically recommend heat resistant flex or is T&E ok too? And if using T&E, is it ok to use some of the spare 4mm or 10mm I’ve got left over from before instead of using 2.5mm?

Also, @EFLImpudence, in this previous post https://www.diynot.com/diy/threads/2-5mm-versus-4mm-flex.384912/post-2953741 you recommended upgrading the cable to match the size of the breaker. Just wondering what was different in that scenario (with apologies if I’m missing something obvious)….

Thank you both for the replies. When it comes to connecting the oven(s) would you specifically recommend heat resistant flex or is T&E ok too? If using T&E, is there any harm in using some of the spare 4mm or 10mm I’ve got left over from before instead of using 2.5mm?

Thanks for that. So are we basically saying that an oven or hob is unlikely to produce an overload unless it's something really major (like a dead short) which would trip any size MCB before any of the wiring got close to melting? If so, why do some people recommend an extra consumer unit for...

Yes, I agree 10mm² is overkill but equally I'm not inclined to rip it out and replace it. ;) If I use the double outlet plate and 4mm²/2.5mm² cables as you suggest, what happens about the fact that those cables are then being protected by a 45A MCB when their current carrying capacity is much...

Hi, Hoping someone can help with the following cooker/hob wiring query as I've searched the forum and can't find a definitive answer on whether I can supply multiple appliances from a single cooker circuit without installing an additional consumer unit in the kitchen. First some...

Thanks, John. The SPD has actually only been installed since yesterday rather than for months, but I still would feel happier if they replaced it with a fresh one on Monday. I didn't know the SPD requirements dated back that far. My original reason for asking them to come back and retrofit an...

I don't think I ever saw the earth wire. They arrived with the MCB and SPD already unpackaged. If I'd seen the unused length of green/yellow I'd have queried it at the time.

Hi, I had an additional consumer unit installed in October as part of a solar install. It's a Fusebox 6-way RCBO board with circuits for 2 x inverters and 1 x EV charger. Yesterday, the guys that fitted it returned to retrofit an SPD - which wasn't fitted at the time (probably because it was...

Thanks. I'll try that at the weekend. And yes it is an S-plan system. It is still the original open-vented HW cylinder, although I'm not sure where it vents to now that the pipes to/from the F&E tank are capped off. Presumably it vents to the expansion vessel in the garage and then to the...

Throughout the time I've had it as a sealed system (about 14 years) it's required top-ups every month or so. I've always put that down to things like a weeping bottle vent (fixed at the weekend!) and other small leaks that I've assumed would be inevitable in a system that dates from the last...

Hi, On Saturday morning I started draining down my system ready to do a few jobs that I'd been storing up for a while. It's a big system with 8 x double panel rads, 1 x single, and 3 x towel rails plus the hot water. Within a few hours, the system had drained enough for me to be able to do the...

Hi, I’ve got a garage which has what seems to be a bitumen felt DPC. Originally there was pointing over the DPC but over the last couple of years this has come away so the edge of the DPC is now clearly visible between the two courses of bricks all the way round the building. See photos below...

Thanks flameport and JohnW2 for your helpful comments. I went with your suggestion and did all the new sockets as spurs. All working a treat. :-)

Well I never knew that. So (provided you can cram four cables into the back on one socket) you can spur two double sockets off one existing socket on the ring, but you can't spur off from a spur (i.e. daisy chain). Have I got that right?

Minimal. It's going to be powering a network switch and a couple of IP cameras. There's minimal junk in there - that's all in the loft of the house! The electrician I spoke to suggested conduit was needed because the cable was potentially at risk from human or rodent damage if it was just...

Thanks, John. Re-phrased questions were the same but without reference to a new ring. ;-) The TPC recommended mechanical protection in the loft space on the basis that it wouldn't add much to the overall cost and reduced the risk of any damage from, for example, mice.

Apologies if the date is wrong. It was copied directly from the Department for Communities & Local Govt website. The person is already on board. In an effort to steer this topic back to my original questions and away from discussions about who can/can't do the work, I'm going to rephrase my...

Point taken, John. But in this particular case, the fact it is notifiable won't cause any extra hassle or expense. So that, plus the fact that if I did it with spurs I'd need two spurs off one of the existing sockets (which is obviously a no-no), means I'd rather go for the new ring. And of...
