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.

Looks like TT as there is nothing connected to that earth terminal

It can easily be TN-S: Almost all of the TN-S installations I see are splitcon and terminated like this. Even the three phase heads have similar arrangements. Also on a replacement head from cast iron last year, the PILC was terminated inside the service head (including the sweated earth...

White vinegar instead of fabric softener works well. Half way though natural drying give the towels a vigorous shake in both directions and once again when dry. Job done :)

How much energy is used by dishwashers and washing machines by the motor? Hardly any - the main consumption of energy in these devices is the heating element. If I do a cold wash on my washing machine, it consumes only 0.04kWh - a whopping 0.44 pence! The difference in brightness from...

I can't think of any that are specifically designed to work at 220V. Appliances with heating elements are only designed to work within a range of voltages and will get the work done quicker at a higher voltage, probably most of the loads in a house will have SMPSUs in, which actually are more...
