At 7pm today 556 watts, 12th 200 watt, 11the 584 watt, 10th 643 watts, 9th 665 watts, 8th 468 watts, the 4th however was 284 watts, 3rd 282 watts, so the output that late at night does jump up/down I can only go back 3 months, and this year solar output has been very high. 1st of 5 whole day...

We have no idea if TN or TT, or anything else, so we can't say this or that should be done, but either a SWA is isolated or earthed, it should not be half done. So we can say it is wrong, but not what should be done. What seems to be demonstrated is it's not the work expected from an...

I agree, in the words of the boyfriend remote, "Do it again, and do it properly" However in general no installation is perfect, and we often seem to get what we are prepared to pay for. But the are limits, and he has clearly exceeded the limits, to the point where one asks what are the bits we...

Comparing 11th and the 12th, from a 6 kW array, OK it was down, but since down to 362 watt anyway by that time of day, can't see it really having an effect on national grid? It does point out why we need batteries to bridge the gaps, and the solar eclipse was nationwide at around the same...

I had one in a caravan, as @Mottie says, it just sat there. But was connected with flexible pipes.

It does list tradesmen to avoid.

I find my house will cool 22ºC to 17ºC from 11 pm when heating turns down, to 8 am when heating turns back on, during the cold days of the year. So 9 hours it can drop 5ºC. I don't like it warm when sleeping, or cold when awake, so only real option with a heat pump would be to sleep during the day.

Seem to have heard that before Is it a Labour Party thing although I think they have failed to update, today homes have solar, so turning off homes could cause us to lose microgeneration.

Why down lights? My room also an odd shape, and the ceiling lamp is to one side, so I use cabinet display lights, and up-lights, and spotlights to add to the basic light. The main thing with a large room, is often you don't need whole room bathed in light, my billy bookcase display lights when...

There is no reason why a heat pump should not be driven by an oil engine. There are with refrigerated transport often duel fuel electric and oil engine. However, to get top efficiency with a heat pump, the motor speed is adjusted rather than being turned on/off. When I played in 1980, only...

I was paying around £800 a year before Trump, so it does seem something wrong. I asked one question when it was suggested to me to have a heat pump, with an electrical failure how long will the central heating continue to run. With oil, it would depend on how much in the battery when it failed...

In essence, I agree with @Murdochcat it is clearly up to the inspector, unlike an MOT there is no hard and fast coding, most follow electrical safety first, but nothing says you must. "5. Move light circuit to 6 A mcb" I can't see why the old regulations said "559.6.1.6 Lighting circuits...

Oh dear, where the telephone is, there is no socket, there is an extension lead kitchen to hall where the telephone is, but really want the telephone where we have an EPS socket, or telephone will not work in a power cut. Unless the new fibre comes with its own back up battery.

On the Falklands we had two small generators to power floodlights, one was around 3 kVA and the other 6 kVA one with a single cylinder lister the other with a twin cylinder lister, and they looked the same, except one larger to the other, but in fact the 3 kVA could burn its self out, but the 6...

My comments have been flavoured due to my own problems. I had expected to find the problem reasonably fast, the replacement RCBOs are type A bidirectional double pole switching, but not the old ones, it said on the packet type B, but it seems they were curve B type AC single pole switching. So...

Yes, it would cool the fermentor, but it would also make the room damp.

This was also my problem, which is why I went all RCBO. But, using an emergency torch can remove the problem of lights failing if anything better, as also covers grid failure, so down to you and a risk assessment. Last house outside lights would give me some light, this house I am left in total...

The domestic distribution board can be type tested, which means under 125 amps total, single phase, and all within the board has been tested to be used together, so you can't have a mixture of makes, or put items like a bell transformer from another manufacturer in the board and this is called a...

My daughter stuck black insulation tape over the LED, but that resulted in us not knowing when the battery had failed.

My landing light, likely does not comply, my wife got a chandelier, which I refused to fit, it required leaning over the stair well, and I was not impressed with that idea. But she got my son to fit it. 5 x GU10 bulbs, which would likely wake me if switched on when asleep. So fitted a relay...
