No, but as to the rest, not sure, maybe the supply was being unlooped? But your inverter should have shut down if not supply, if there was no supply, how long does it take a smart meter to re-boot, I don't know.

There are a load of things which can be plugged in which do not even conform to BS 1363. Never seen one of these marked with BS 1363, and I have seen a website called fatefully flawed where they point out the dangers, so all we can do it put them in a bag and present to owner to bin them. As to...

OK 80s so no council records before I think 2004, so if to good standard I would just TT the installation to shed, but it's up to you, you're the one who has to sign the certificates and register the work, so ask your scheme provider. In England one could just do it and run, but since in...

There is no MOT hand book equivalent for an EICR, it is up to the inspector, there is nothing to say they must even use the codes, it is down to the inspectors' opinion, he can code as he sees fit. I would not code push in blanks myself, but neither can I say it is wrong, I see both types shown...

This is why we should look at the installation certificate before doing alterations, but with domestic we know that certificate is unlikely to exist. So one could make the shed TT, but the tests show a joint somewhere, and we simply don't know where, if an insulation test shows clear you could...

If the blanks can be removed without a tool, and there are live parts exposed when removed, then one could not say he is wrong. The blanks should be of a design which will not allow removal without a key or tool. These are firmly fixed, it needs the cover removing to take them out. I...

Agreed, but there are many actions which can cause something not to work, so if for example a surge could cause it to fail, would the lack of surge protection device also mean a code C2?

The change as far as I am aware is you can't put the batteries in a loft space since if the house caught on fire, the fire brigade could not fight the fire in case the batteries exploded. I have heard of not regulations stopping batteries from being fitted in a garage, in fact that would be a...

Simple answer is, the unidirectional RCBO does not cause a potential danger, it may blow a transistor or whatever it was, but that did not cause a danger in its self, and if it has blow due to the test button being pressed, then likely the fault will be found next time it is pressed. May as...

It is the Sky app stopping working as when the router rebooted it assigned it a different number, and the microwave and cooker clocks needing resetting, and bulbs auto switching one when power returns. I hate turning the power off, as so many things can mess up when you do, so if the power...

OK the modern volt meter is likely a comparator same as the valve volt meter. But I am sure someone wrote a law about the relationship between volts, current, and resistance, OK I know it is AC so not a resistance but an impedance, but that is just splitting hairs, the ELCB-v used voltage to...

Mineral insulation used in some cables and heating elements is Hygroscopic that it attracts and hold water vapour directly from the surrounding air, so the seal on the end needs to be very good. Once the seal is damaged, heating the cable or element up may drive out the water, but it will draw...

Yes I have same problem, I use the sun to dry the clothes, the sun shines on the solar panels, and the electric produced runs the clothes drier. I moved from a very simple drier, vented, to a complex condenser heat pump drier. The old one had a switch at back, 1 kW or 2 kW and a reset button at...

I know the test procedure has changed, there was it seems a problem with some special RCDs when tested as we were originally taught. I will hold up my hand and admit I have not got a copy of the latest guidelines, but they are guidelines, and some skill is required when working out how to test...

Yes, I started a thread about this problem, we in real terms have many RCDs where we have no idea if bidirectional or unidirectional, even the data sheets don't help. It does really need a risk assessment, a socket mounted low down in a bedroom, so the bed head is above the socket level so the...

Except for the valve volt meter, all our volt meters measure current.

You're showing your age, I know 50 volts to earth tripped them, and parallel paths could stop them working, but when found they were just ripped out, never did test one.

Oh dear, I suppose with the old ELCB-v there may have been a point, I never ever tested one, not even seen a tester other than pictures looks the part, but never used one. Must have missed that day in collage.

The whole point of testing with the test button, is to alert one if the mechanism has got glued up with dust etc, and to test with a meter will alert one if the device has stuck, better than the button, which in general sends more than 30 mA. It does not test speed or ½, full, and 5 times, with...

I suppose I should have used an emotion ;) to show I was not serious about it attracting a C2, it does seem that the test button needs using to cause them to fail, so reverse direction and test button at the same time is unlikely. Not following the regulations is abuse in the same way as...
