Hi,
Renovating property, done most & unfortunately (stupidly) now realized there is fair bit of VIR rubber cable still installed in the lighting circuits.
The ring has been done, all circuits proctected by RCD etc.
The cable surprisingly seems in good condition but appreciate only whats...
Hi;
In order to install an EV Charging point at the rear of our Garden for the Odd Designated parking bays we have, the reinforced cable for such would have to run the length of the Garden - where there is a hot tub Present.
Do these cables need to be x metres away from Hot Tubs? I'm getting...

Hi everyone,
I’m planning to install a home EV charger and need advice on the best type of cable to use. The charger will be located about 15 meters from the main consumer unit.
What cable size and type should I use to ensure safety and efficiency? Should I also install an isolator switch for...
I have a situation where we have altered nearly 100 new circuits purely by adding a cable from the supplied isolator to a 3p+n plug to supply pumps. Each isolator is on its own circuit from the local DB and we need to issue certs for all these alterations, I was curious if there was a...

Three phase board supplying lighting and power circuits.
Cable ran along a corridor on cable tray/ladder.
Online Cable calculators saying the run is OK for 25mm 4core but when I’ve used the...

Hi,
I am currently working on the project part for my C&G 2396 design qualification. I have passed the exam but that was 2 years ago and I have forgotten so much😕.
I cannot for the life of me get my head around calculating and designing the sub main cable to a 3 phase DB with a mix of 3 phase...
What size cable is used to connect a residential 100amp sub panel from an existing 100amp panel, 75 feet away?
All Breakers will be removed from the main panel and move to the new subpanel.
Hi all I was hoping for some guidance as I'm preparing for the AM2. I've seen comments online saying a question came up in the AM2S that I'm struggling to find an answer for. When using a tester on data cable what is the cause of a light showing on the master unit but then it's missing on the...
Removed a rotting picket type fence on our campsite which supported 4 electrical 10 amp hook ups and replaced with new fence. As the new fence has different post spacings the previously installed SWA cable is either to long or worse to short. As the cable is above ground and running along the...
Hey everyone,
got a bit of a dilemma here, I installed an isolator in a meter cupboard, unfortunately, I really did not measure things up and trimmed the SWA steel strands a bit too short, an EICR was conducted and this was flagged up. I don't think I can get a gland in anymore so wondering if...
Can someone please explain me how type B MCB can protect a cable if it only trips when current is 3-5 times maximum load?
Let's say, 2.5mm radial circuit is protected by 16A type B MCB. Prysmian 2.5mm T&E current rating is 27A. How will 16A MCB protect the cable from overheating and burning if...
Hello All,
I'm in UK, and I'm after some info to help a family member in Ireland.
They've been advised that the cable to their earth rod needs to be upgraded as it's apparently too small. Want to reassure them this is really needed before they pay for it to be done.
I'm used to what BS7671...
I have run 10mm2 3 core SWA to garage CU but miscalculated the length and no way Im going to reach the house CU. I need to extend the cable, is it acceptable to do it like on the picture?
I’ve noticed my main incoming armoured DNO cable goes up the garage wall in some capping to the ceiling then runs under the ceiling and drops down to the meters. Is this ok as it’s armoured?
I'll start with the problem.
I've installed two Hive Mini Pro 3 EV chargers, and both have had the same fault, which I think I've now isolated to the CT Cable (Not the clamp or its direction).
Essentially if I connect the CT Cable to the EV Charger and enable smart charging, the EV Charger...
