Not that I was referring to 16A circuits, I also recommended that Jack seek out an electrician or suitably qualified person to check his cabling before putting it into use.

Stop trying to back peddle now that you’ve been called out 🙄

So are you saying that any 13A plug board with a 16A plug on it is fine without a fuse and would pass PAT?
I always understood that as they're only rated for 13A, they needed some way of limiting the current i.e. the fuse

Look at the curves of a 13A fuse against a 16A C-curve MCB for which one will trip first on a sustained 20A draw

Hint: an average 13A BS1363 fuse will sustain about 21A indefinitely

This is really were it comes down to the simple fact that you need to know what you’re doing, not just follow the DIY electrics guide.

Much as this thread is a joke, the hilarity of PAT still ranks above it.

In summary, export an unknown mains topology 25M ( with may or may not be with a viable extension of Earth system ) on a 13A source-feed.

OK given you have no f**king clue about earthing ( assume PME, as a 85% bet) 25m is pushing it a bit.

Use conductors equal to (or above) incommer and the rules change but given you don't know what an incommer is or what earthing systems are lets be real.

given your whole leg is definitely "final distribution" you are definatley in a 30/30m A/Ms RCD scenario, unless you can prove design otherwise.

So Based on 19 mV/A/M for H07RN-F and 3% max drop you can only run 15.16A @ 25M, the 3% is dodge as you are not running POD to endpoint, just hanging off an unknown supply, but in real terms i) 2.5mm is not good for 16A 25m (shocker) 
ii) as long as you have the right trips in place you are with realms of fine.

Sorry it took 4 pages of crap, but this is where we are at, You Tube, Forum monkeys all with no actual real world qualifications oozing poo.

IMHO thhe BS xxxx shite is a tiny part of the regs and is not carte blanche to read a bit and claim you have a clue, viable design and mechanical protection for all conductor at all times is a requirement, the document needs ripping up and embedding into the 18th, if you don’t have the ticket to rollout out a safe job, reading the “idoits guide to lobbing a few cee-forms about” is gonna make you more dangerous not less!!!


Always remember data + Context = information, that pile of data IMHO defies context!
