An overload implies a higher than normal current. A high resistance connection cannot cause a higher current to flow.

Silicone and PVC are fine together. You don't get any reaction from these two materials.

So that the fire doesn't spread (quickly) to another dwelling.

Philips Master 4W and 7W versions are very good.

Yes, this is what I use :)

Looks like this guy is asking the same question on every forum!

Socket & See make the full range of test instruments. Is the brand name being confused with the little plug in testers in this thread?

It'll most likely be something the wholesaler won't be able to supply, as it's highly unlikely that they require a high power LED driver (1/3/7W). Remember that LEDs can't be driven by a constant voltage, so unless they already have some form of current limiting you'll end up blowing them all if...

Jesus :yellow card where did you learn your theory?

Sorry, what????!

Thanks for your reply Sidewinder. In terms of your question about plug mounted or in-line SMPSUs, if the output is below 30W the outputs must be fully protected, meaning the voltage must collapse on short circuit and not cause any danger from overheating. They must also be isolating, which is...

I used to go through bits like nobody's business. I finally bought a set of wera impact bits and bi-torsion holder and 18 months later I'm still on the same PZ2 and PZ3 bits!

I'm not thread baiting, it's a genuine question. The parts are not 'live' and are separated extra low voltage, so would cause no more danger than a 9V battery with the terminals exposed. The remit of the PAT test is supposed to be portable appliances over 55V, but that ends within that power...

On what grounds wouldn't you pass it? It's not electrically unsafe, is SELV, and the outputs from SMPSUs are fully short circuit protected. Surely you're only testing for safety on the mains side

Looks like they're using the neutral as the earth too.
