I know E7 existed, and I know how it should have been wired, but in real life, only seen a white meter once in my Uncle Trevor's house. And so long ago, no idea how it was wired. As @SUNRAY has said the split was before the meter, when using the white meter, clearly not with Henley blocks, so...

My smart meter 5 inches wide, and 7 inches wide, but needs another 4 inches below it to have a reasonable curve for the cables. My old meter this type and there was not enough room to change it. Other items on the board had to be moved first, but I wanted a smart meter to be paid for export, so...

Not quite, it depends on the ballast used. With a single tube and a magnetic ballast yes, easy to simple swap. However once you go to electronic ballast and twin tubes not so easy. Also even with a magnetic ballast, the ballast acts as a resistance, so typically a 58 watt fluorescent is replaced...

I have a controller for the immersion heater, and as you infer it would be better with a simple time switch, but that is because of the tariff I am on, where off-peak costs less than I get for solar. As to photo/PIR cell, I do have a rechargeable torch at top of stairs with a photocell, and...

I installed my wife into the dinning room, when she had her knee done to save her doing the stairs, temporary, but felt she would need to turn the light on/off from in the bed. So I got a Tapo light switch, and a magnetic back button saved all the wiring with two-way switching, but the button...

Yes at £8 each, having a timer built into the fan would be cheaper. But the timer is not built into the fan. 12 Ah at 48 volts = 576 Wh but used 507 Wh which points to the battery not being 576 Wh. But one cost £10 and four worked out at £8 each, so was worth getting the group of four.

Well charged and switched off. The other graph interesting, but seems a lot of money to draw a graph.

It seems likely I was correct, to see power used like this, does help to work out what was used. Max the motor can produce is 350 watts, seems likely I produced 250 watt, but max speed limited by gear ratios, around 12 MPH is my sustained speed, but motor could easily get to 20MPH, at help level...

I see 16 amp MCB marked garage, and a 32 + 6 amp MCB in the garage, this should not be the case. With caravans (often a 16 amp supply) I have seen the 6 amp after the 16 amp, so the 16 amp takes the whole load, and also 10 amp and 6 amp but to put a 32 amp MCB fed by a 16 amp is daft. I will...

The zigzag config was done a lot at one time, it was common for a generator to have 12 windings, these could be arranged to give 55-0-55, 230, or 380 volt phase to phase. The use of just one phase, would depend on which phase the regulator monitors. That is if you have a regulator, control...

More about switching them off. The old fan I bought on holiday in Spain has a built-in timer, and would switch off after time set. All the new ones seem to not have timers, and to direct the air around the room the whole fan turns, where old one, had a disc with directors which moved where the...

I have seen the advert of course it is silent to those in the house, it's outside, it is the neighbours who have to put up with any noise. But winter likely everyone's windows are closed, only in summer will those without the heat pump have their windows open, that is of course if that model is...

Well test done. Notice given on phone, the battery charger showing bright lights. But as to why one would want the feature, not so sure! Although telling me when the batteries have been charged may be handy, but I like to have a rest between discharging each set of batteries.

I read about charge guard, which it seems monitors the power used, by a battery charger, and once it drops below a set level, starts a timer to turn it off, I can see with my drill batteries this would be useful, as the 6 green LEDs which show when batteries are fully charged light up the...

I needed some more for fans around the house. The main thing is the auto off timer, my old fan had a timer built in, so would auto stop, new ones that function is missing. I use Tapo (TP-Link) in the main, so three versions look the same, P100, P110, and P110M the P100 does not have the timing...
