Thank you for another very helpful response. Just to assure you we are saying the same thing, I was referring to the 2.5 on 20A radial which I now understand to be technically compliant but still seems to be drawing criticism from some folks here. I respect it leaves little flexibility for...
Good call out thanks. This CU is actually for an Air Source Heat Pump.
The contractor (not the guys who rewired the rest of the house) put in a great big 10 way CU for 3 ASHP MCBs. It's only on a 45A RCBO but the ASHP/Immersion never draws more than 15A. Obviously, it's less than ideal if it...
So helpful and sincerely appreciated. Thank you.
Rest assured, I will get this checked and notified as part of a more complex battery install i'm having done professionally next month. I am a stickler for paperwork, and this is as much about my curiosity and wanting to learn and impress my...
That was my inclination yes - I had understood from several calculators and manufacturer specs that 2.5mm 3-core clipped to external wall would be adequate for my couple of sockets to my shed? It would also be fused down appropriately.
While my main board is new and the secondary CU is on a 40A...
What a brilliant group, thank you for the interest in my issue. I’ve learnt a lot already from the feedback.
A 20A radial then from the second CU then. The SWA is clipped above ground so no issue there. It’s a short but awkward run hence my inclination to go light.
Reading between the lines, I...
Quite right - seems this was a diagrammatic error upon checking, thank you. On checking the secondary CU does not contain an RCD. I'm now thinking this is overengineered for my purposes and that I'll just put in some SWA, and my friend can hook up a simple radial circuit when he gets time. Much...
Hi,
I'm looking to get the lionshare of a small shed wired before a friendly electrician does the needful. I'm a confident DIYer, but I would appreciate any more experienced view to check my logic.
My house was professionally rewired in 2022, but I would like to connect a small 8x6ft shed to a...
That is so helpful, thank you. I had not appreciated the significance of DLM. x10 11kw chargers on 63A is incredible. I don't think the charging power needs to be more than 7-11kw anyway as our preference would be to have a greater number of slower overnight chargers vs. a couple of expensive...
Huge help, thank you. Nice surprise to
Learn we have three phase after all. We have local electrician coming next week to assess capacity and your suggestion might at least provide a nice interim solution to last a few years before we upgrade supply. Thanks again.
We have an unusual situation being a British-run ski lodge near Chamonix, France. The chalet is a 1930's, 20-bedroom facility run for around 200 private members that include a growing number of EV owners.
We would like to get three 7 or 22kw EV charging points installed in the car park but...
Hi,
Apologies in advance if this is in the wrong forum. I tried to post to 'Electrical Advice' as a DIYer but had issues.
I'm laying SWA (about 40m of 10mm2 as advised by a pro) to a new workshop building that will have its own CU, circuit and ground spike. I want to do the donkey work and lay...
Another clue being that the meter is 5+ meters away in another room (a separate garage that was added 10+ years after the house was built) and has a card labelled \'99'. I'm thinking of moving the CU next to it again as part of the intended works. It's hard to imagine this install being earlier...
