Thanks Harry. I forgot to mention that the sockets are on opposite sides of a cavity wall, and are both surface mounted. Hole is 12mm, which allows cable to pass OK but there is some resistance when pulling. Not sure if the cable needs to be significantly downrated when passing through (cavity...

Thanks EFL. If that is OK, then great. It just felt that any possible risk of even the slightest tugging force on the other socket was wrong, so just wanted somebody who actually knew what they were talking about to confirm. Much appreciated, as always.

Hi, I am in the process of wiring two sockets, on opposite sides of the same wall, with the sockets directly behind each other. Just to be clear, this would mean that the wires are connected to socket 1 and then the cable goes from the middle of the backbox, straight through the wall to the...

Yes, but I bought the FCU with the original intention of CU->FCU->Internal Socket->External Socket Which should have been fine except the FCU is Type AC and the External Socket is A. I never expect that the RCD would protect the supply side. I've decided that, for now, I am going to simply...

Thanks for all of the advice. The outdoor socket will be used for power tools (including lawnmower, strimmer, mitre saw, plunge saw and various others). It will also potentially be used to power portable lights. The only other thing that it is likely to be used for is a bench top power supply...

Hi, I am planning to install an outdoor socket as a spur from an existing socket on a 16A radial circuit. When initially looking at the work, I realised that the circuit is not RCD protected. Because I wanted to keep the internal socket, I decided that I would buy a FCU with RCD, put that...

Thanks to both of you. As John says, it makes sense that if the issue was such that the work couldn't be tested it would be a problem. As most of the installation is old (not sure how old but probably at least 20-30 years) I was expecting that there could perhaps be issues with resistance...

Hi, I am hoping that somebody could help me with a quick question, please. Can an electrician make changes to a CU (either adding RCDs to existing circuits, replacing MCBs with RCBOs for existing circuits, or changing a whole CU but not adding new circuits) and sign off the work, if there are...

Thank you @EFLImpudence. Very much appreciated. It's taken me the whole evening faffing around with figuring out a good pattern, while avoiding the joists, so any time saved tomorrow will be a great help! :) Thanks for all the other points too. I'm only using 1.5mm because I have, but note...

Hi, I am currently in the process of replacing the lighting in my hallway. The existing light is a single fitting, which sits halfway down the hall, directly below a junction box (pictured). The light is wired to two switches in the hallway. My plan is to - replace the current junction box...

Hi, I am going to be creating a shower enclosure with shower panels. They are 10mm PVC, and are tongue and grove between panels and an aluminium corner profile. Under the shower tray will be 18mm marine ply. There will be two panels on one wall, and one on the other, so a single t+g connection...

Thanks for the help with this. Just wanted to note that I finally got the swept bends and they measure exactly 40mm. Might be helpful for others in future.

Thanks Madrab. I was a bit surprised to see the notches so deep in the joists. I was aware that they were too deep, but thanks for confirming what the max depth should be. I certainly won't be cutting into them at all. They were supporting a cast iron bath previously so, although they have...

Hi, I am looking to install this shower and tray in a bathroom that I am refurbishing. https://victoriaplum.com/product/mode-hardy-8mm-easy-clean-shower-enclosure-and-stone-shower-tray?options=size|1400_x_800 I'll be replacing the sink and toilet too, but I am keen to get the shower installed...

Thanks @SimonH2. I'm trying to read up on the difference, and how to identify it. Am I correct in thinking that the above is the same as "1P+N vs 2P" with some 1P+N products being described as 2P?

Thanks very much @SimonH2. Lots to work through there, and all very much appreciated. I've started by having a look at some DP RCBOs, and I am wondering if this one is OK, in this enclosure? https://www.screwfix.com/p/wylex-16a-30ma-dp-type-b-mini-rcbo/8541x...

Hi big-all. I'm going to try to place it around 50ft from the house, am I also want to build a housing around it (for security, weather protection and also noise). Not sure how quiet I will get it, but then again it is only for use in an emergency, so hopefully the neighbours won't be too...

Thanks. This kind of thing? https://www.amazon.co.uk/15mm-Long-Radius-Bends-Feed/dp/B0776KGDN4 Any idea what the bend distance would be compared to a pipe bender?

Thanks. I am going to give it some initial testing over the next few days, to see what it can handle.

Hi, I am currently working on the pipework which will feed a thermostatic shower. This one to be exact: https://www.wickes.co.uk/Mira-Honesty-Exposed-Rigid-Diverter-ERD-Mixer-Shower/p/233965 I am going to batten and plasterboard the wall, and want to minimise the gap and also avoid chasing, if...
