Hello, I fitted some extra sockets in a bedroom two years ago, and the customer has said that 2 of the sockets make a high pitched whining noise, all tested at the time readings fine etc, I've attached a video, doesn't sound like arcing to me as it's not a crackling sound? I've told them not to...
I'm a bit of a gamer and over the years i've amassed a collection of consoles i'd like to have easily accessible. Now i understand that if i was to just grab an extension lead, and hook up all of them to the double socket i have nearby, that i'll likely overload the socket and this poses a fire...
I need to set up a 40 kW grid tied PV system on the roof of a condo with multiple user. The objective would be to feed all the different apartments each one of them with its own DB and meter. Is there a solution smarter than splitting my solar system into smaller independent system (e.g. 10*4...
Could somebody please put me on track.
Main bonding conductors are sized relevant to earthing conductor (TN-S / TT) or PEN conductor (TN-C-S).
On a large installation (Industrial / Commercial) with multiple buildings containing Extraneous parts should ALL the bonding conductors be sized the...
Hi all, been a while ;)
Typical me, got a right arse of a project on the go where absolutely nothing is 'standard'. Story short, currently installing a BNO system for a BMO (try saying that in a few hours after a beer...) and have incredibly limited space to juggle umpteen SWA's, a Ryefield...
Hi Guys,
I have to fit an MK 3 way grid surface mount box below 3" metal trunking and require the use of all three knockouts on the top of the MK surface box. This needs to be repeated for a number of surface boxes.
Cutting one hole in the trunking for a 20mm coupler and bushes is easy, but...
Evening chaps
I’m first fixing a new build this week large high spec 4 bed house.
The builder would like multiple bt points throughout the house what’s my best way of doing this as I’ve not done a lot of it.
Should I make one the main one then daisy chain off the rest like a radial?
Buoyed on by my first successful ceiling rose replacement, I’m now doing a second one, but have come across a slightly different scenario.
In this ceiling rose there are more wires than previously, so my question is, is it ok to place multiple wires into a single connector in the new light...
Hi everyone
I'm busy rewiring a restaurant and the customer has asked for USB outlets at each table. I think it's a terrible idea - I'd be happy for my phone to go flat when eating out - but that's not the point! The type he has asked for are just USB outlets and not the ones combined with 13...
Hi guys

(1) How many ports can I safely install?

Under what (if any!) circumstances is it permitted to run two separate cables to make up the conductor surface area of a larger cable (which, in this case is impossible to install...
Need to change 2 6mm radials for a single 10mm, but it's going to be near enough impossible to draw through a...
Hi all,
Having a brain fart...
Looked at a job today, have multiple exterior lighting circuits (4x MCB'S). Can see why there is multiple, as previous electrician was worried about cable lengths etc as the property is quite large.
But seem to have multiple Photocells and timers controlling...

this is a eaton cutler hammer circuit breaker. The house was built in 1969 but the breaker was upgraded to this eaton 9 years ago when i bought it.
House uses mostly older outlets that are 2 prong, not 3 prong. HOuse does...
Hello
I’ve recently had to rewire my home alarm system as the engineer who installed it did such a shoddy job that all the cables were hardly in and causing the system to trigger every couple of moments. I’ve recently been able to get the system working correctly however, I am unable to set...
If you’re on a job which involves things like just replacing light fittings and odds and sods on different circuits for the same client, is there a MWC that can cater for more than one set of circuit tests rather than doing separate certs for each circuit?
Just practising filling out paperwork for upcoming assessment. Come to abit of a stumbling block.
There are x2 3 phase circuits that have more than 1 method of installation.
Which reference method do you list on the schedule of tests results?
Also, for max Zs of the operating device, are...
I have installed 4kw (5kva) solar system at my home. I have 3 phase supply (3 single phase meters instead of one 3 phase connection, i.e 3 separate phases and 3 neutrals, These neutrals are combined at source end of utility company) from the utility company. when I shifted load of one kwh meter...
Is it possible to energize a contactor/relay from multiple toggle (not momentary) switches in a way similar to 3-way switches?
If so, what components and setup would do that?
The purpose is to control lighting from several sources and the reason for not using simple 3-way switches is that the...

Hi all, first post, and it relates to quite a challenging installation.
The short version is that I'm working through remedial work on a 75 page EICR on a site with 24 distribution boards, hit a very nasty C1, have resolved it, but now have max Zs issues that were actually there before but not...
