I was testing a consumer unit before upgrading to current standards. (Old re wireable fuses) when testing one of the ring mains continuity i found 38v on the cpc with that circuit disconnected. After carrying out end to end tests on Line and neutral which came back fine. I found the voltage...
Hi all,
I hope you can help, I'd like to extend a ring main into the an outbuilding and be able to isolate it if required.
I'll be using power tools and wanted about 4 double sockets in there so didn't want just a spur.
I've attached an image, is this an acceptable way of doing it.? The...
Looking for some assistance here as I have received different bids from different electricians. We live in Florida and have a Generator for emergency use, but have no way to power the house save for an extension cord currently. We are also remodeling our kitchen and are wanting to upgrade our...
Firstly, just to re-assure professionals here, all tie-in and testing on this project will be undertaken by a qualified electrician. This post is just to improve my understanding.
We are preparing to have solar and wind power generation facilities at our home and the first phase of this is to...
Hi,
I've just bought a new built-in 3.4kw oven = 14.8A @ 230v. I'm getting 245v so actually 13.8A.
Existing oven plugs into single socket fed from 20A DP switched fused spur.
Ring is small (3 double sockets) with 4 x 20A DP switched fused spur single sockets (oven, washer/dryer, dishwasher...
I have a new combo meter box and 200A main shut off installed outside professionally. It has 4/0 service line coming into it and I have confirmation from the electric company that I am good for 200A service supplied to the house. Previously, there had been no main shut off. The new...
1990s home. 100 amp main feed. Nevada. 15 years mechanical experience on cars + motorcycles.
Previous electric exp: I ran the other 50 amp 4-wire setup directly from the interior subpanel.
Now I was told by an electrician when I was shopping around to get the above job done, and a 30 amp plug...
Hi all, I really hope this is the correct place in the forum.
tldr; Oven and boiler take turns to trip the breaker, but I don't think it's either of them so any help would be greatly appreciated.
Basically the main breaker keeps tripping in the house I'm renting. We've been living here for...
I have two main panels each 150amp breaker. House was built in 83 and lived here for 6 years no issues. About 6 months ago we had a power surge and our main ac fail (hard short) and tripped the breaker. Had the unit replaced but it seems since then we have had issues with lights diming and...
I need to free up space for a 50 amp breaker by combining 2 20 amp into a single tandom breaker. I can not find any information on this model number. Will this lug accept tandem breakers.
Called out to rental property i carried out an EICR on in March; this year to look at loss of power.
Narrowed it down to the down stairs ring main, done end to ends and ring in tact, insulation resistance failed, dropped every socket and inspected the wiring and socket fronts which 2 i had to...
Hi there thank-you for taking the time to read this! I have a 300mA Rcd in a grain shed on a farm now every time I try reset it won’t stay on there are 3 phases that go into the main switch
And it isolates all 3 bar the neutral so when wen everything is turned off mcb rcbo in the board it...

Installed 40 years ago, water/gas/structural bonding required, these are @ 10mm
Tncs earthing system @ origin which is remote from buildings 120mm tails.

Hi,
Can anyone tell me what material the main supply cable is wrapped with (I believe this cable is owned by the DNO).
My concern is whether it is Asbestos?
The below photo of the cable taken just below my cut out shows the unpainted section facing the wall to be very fibrous.
Also, another...
Hi all, looking for a bit of advice and confirmation on my proposed plans for a SWA sub main to a ISO metal storage container. I've calculated the max demand in the ISO will be about 20A (300w of led lighting and 2 double sockets for chargers etc) It will be fed from a 3ph DB in another...
Over the years as a DIY-er I've used the old brown 30A circular junction boxes to add spurs to ring mains. I like them as they are strong, secure and visible. I've ALWAYS followed the rules on domestic electricity . Until earlier this year I've been able to check with a cousin who's a...
My main incoming rcd is tripping out as soon as any load on any circuit. Have pulled each circuit out of the board live and neutral in turn but failed to isolate it to any specific circuit, is this likely to be the rcd at fault?
Hello everyone ?
It's totally confusing for me. It is my understanding that the neutral and the ground busbars should be connected at the main distribution board (schematic attached), but not at the auxiliary or sub panel. But why?
I know that if I connect them in sub panel the current from...
Was wondering if the gurus can critique and/or provide recommendations on my plan to install two sub-panels in a (50'x100') 5,000 sq ft steel building that I plan to use as a hobby woodworking and welding shop.
I plan to install two sub-panels using two feeder circuits originating from the...
