Any Electrical Sparks here?

Those access push fit holes to the JB are IP rated, sames as the ones Wiska use. However, they are designed for on cable only. Personally I would never rely on them, and then there's the issue over cable restraint. IP rated stuffing glands for me.

If you have a 'sparky' who doesn't test, they are the ones that tie their horse up outside. Its a challenge getting decent trades person, suffer a lot in my workplace, especially when you ask for a certificate of works, even with large companies.

However, testing is there for a reason; remember that 7 year old child that died in a pub garden, due to sub standard work.

For others of you out there, try the Competent Persons web site. But also ask for verbal recommendations.

The only mains wiring is going to feed is a bench top 850W tumble dryer - I think you lot are over analysing things here, the mains socket in the shed will be fused -- I said this previously
and my RCD will trip anyway if excess current or moisture gets into the circuit outdoors, which should not happen.

The Solar controller is feeding the LED strips- 40Watts - we are not talking a nuclear power station here

BTW, I had a sparky fit an outdoor 1000W flood light last year, which was a mains feed and he used a cheapo box to connect the wires and no glands at all

That box looks like it has a crack in the front of it and the cable coming in from the side should have a drip-loop formed in it.....

SWA need special glands to allow the “wire” in the sheath to be used as an earth
The picture you showed of an outside floodlight isn’t wired in SWA
SWA- Steel Wired Armour
This is why we do a four year apprenticeship and continually need to keep up to date with current regulations
And yes I am a spark

I am not a bodge job type at all, in fact I got high quality parts because I know these will be fitted, its the same way I change the oil and spark plugs etc of the car myself with good quality material
as who knows what a garage would use - buy your own stuff, if things go tits up its your problem and not someone elses.

I have a few degrees and a masters in Electronic Engineering so wiring a socket is not exactly rocket science but I still want some guidance on outdoor stuff and when I can see the comments here its prety clear that the last sparky done a bodge job on the flood light, which was around £100 I think or more in labour itelf, far less than what I spent on all the material for this job.

I installed a second one with a PIR sensor using another box, I never used glands but used lots of silicon grease on the intrusion hole in the box and also on the wago connectors in the box - this was fitted well over a year ago in all sorts of adverse weather right in the driveway where the worst of the weather is and no RCD has tripped and the light works fine.

Now, back to this - I will sound out some other sparkys as i do need quite a bit of wiring done in the shed I am to buy, so my preference is to get someone fit it all. I have a batery powered PIR light purchased for the shed so no need for a mains light so that is one less task.

I also replaced the 6942X 2CORE 2.5MM SWA wire which I was to use with the solar panel / battery with red and black 4MM EN 50363-1 solar cables, 4mm is more than what I will ever be using but no bodge jobs.

I can also get them to put glands in the bodge flood light(s).

well I specifically said about 5 times I was dealing with a 12V SELV LED circuit, with a whopping 40Watts, this doesn have a traditional earth - just 5 cores - no earth. I can still use this cable however it has 5 cores and is robust but maybe overkill.

The outdoor floodlight was rigged from the mains, there is an aux power point on the wall which the sparky tapped into to fit the flood light, the weatherproof box in the photo is where the main feed is located and based on what has been said here - he should have used glands

Can address this when I am getting this work done, I never fitted that box, I will replace it with a IP66/7 one.

But how? as soon as you pierce the rubber that rating is gone - which is why I used silicon grease

I can see the barrier that glands offer which is far better than relying on a JB itself

Ive taken the advice on board here from what has been said, I never really had the intention to do this work myself - as 'easy' as it sounds much of it is way too much faff for me so leave it to the experts. The wires i did order have cancelled and getting a refund, SWA wire for one is not good for LED lights as it will have a negative impact on LED lights with voltage drop and way overkill - the H07RN-F looks more suitable that was mentioned but this is where I need a sparky to come into play, also that needs a conduit - I have read that even SELV wires need ground outdoors but there is no ground on the LED lights so how can you ground something that is not grounded itself. --- regs eh

I got a price here, what do we think of this quote

The lenghts of wires needed that I measured were, included a bit extra

3 core SWA mains - outdoor socket to 2 gang socket in shed / w fuse 10M
5 core 12V SELV 12M (this will be divided in 2 as around 5M at going either end of the strip)
Aux 12V 2 core (cctv) - 11M

Getting slabs done next month so need any condit etc layed before work starts

Should all still be tested incase anything happens to the cabling
You’ll need to get a minor works certificate
