Not really, there could be a neutral - earth fault, so may be a problem not involving the switch, but unlikely. I have already shown the tools used by the electrician, not worth buying yourself, so I would say time to call an electrician.

Parent's house, the cold water tank, was just above the cylinder, and up-stairs pressure was low, I did add a pump for the shower down-stairs, and found not really required, but remember the worry was could the pump cause air to be drawn into the cylinder, I was instructed how to plumb it in at...

They can attack anywhere, but other than them, most likely is spider, slug etc. Have you opened the switch to have a look?

The 4 Ah version seems nearly the same size and weight as the 2 Ah version. As to why it needs connecting to the phone so I can see when charged, not sure? Even tells me the battery temperature, and charge current. But why? When the third light stops flashing, I know it is charged, and when the...

375 amps, in the main we need 20 volts, plus 1 volt per 25 amps, so around 35 volts output, = 13+ KW so at 400 volts 32 amps miniums, and at 230 volts 60 amps, so clearly not something one could ever use at home. And I have not considered in rush and losses. What the second part is I don't...

Agreed, point was however as an electrician, can't rely on having grid power, so battery pack, or generator, or direct battery powered tools. Sometimes we can isolate just part of the installation, but in the main, battery tools first, then the second drill/grinder etc, can be mains powered...

Neutral to earth either zero, or very low voltage, if zero then ohms test if neutral switched off then infinity, if not then zero ohms, and if a voltage neutral to earth clearly neutral not switched, so don't test ohms as can damage the tester.

Well lashed out, got 4 Ah battery from Lidi £25, will likely mean other drills also work better, as an electrician, often working with the power off, it is such a pain to work with generators and large battery packs, the cordless tools are really a must, such an improvement on these having...

I would latch the valve bleed lever, and see if it works, if so then wait until summer to change it.

I hope it is OK as my sink directly below the CU. Only showers or baths have special rules, as you're likely to be using them naked.

A RCBO supplies one circuit, when it trips we are 95% sure it is that circuit, note the yellow test button, it may be twin or single pole, but since it is unlikely be protected by an upstream RCD it does not matter. The MCB is normally single pole, so even when switched off, there can be a...

FCU one hopes will have a double pole switch, but the line can be locked off by putting a lock through the fuse carrier. Lights switches not so easy, my light switches I would never trust, I could remove the batteries, but I would always switch off at the RCBO, and to be frank, not sure if they...

Had the heating worked reasonably when we moved in, then likely I would have done nothing. However, it was a complete mess, and my attempts to correct it, were not as required to start with, so I looked at why, what had I done wrong. As I am sure with most who try to improve the heating, I...

Down to age, I was in a house with gas hot air central heating, and floor to ceiling picture windows in the 1978 winter of discontent and after that I vowed never again would I rely on electric for heating. My dad, from Lancashire (although now called Cheshire) would say "You know what...

My oil boiler will continue to run, until my batteries go flat, and the solar could mean they could last for weeks. I also have one open fire, which I do not really want to use. The last house had a gas fire and flue bricks, so again a method to heat house with no mains electric. As long as...

Should give you an idea what they look like and cost, I went for around the cheapest I could find. Again the whole unit, with surge protection and isolator. In the main, an electrician wants to charge by the ½ day, it takes time to move from job to job, and with a consumer unit charge to worry...

I did wonder if the way to go is an inverter generator. At 3 kW it would run all garden tools, the largest is the leaf blower at 3 kW. I have also looked at other battery systems, these do look tempting, but it is still battery powered, and you have leads to contend with.

I have a multi-fuel option for DHW, suppose no reason not to also have a multi-fuel option for CH. As long as both heat the water to around the same temperature. But electric costs too much, even off-peak at 8.5p/kWh. However, I suppose there is no reason not to use either a direct drive, or...

That's an expensive grinder, is it gold-plated? I keep finding the odd job when I need a grinder, but not enough to pay out that much, I do need to get a selection of discs, and one needs to look at the guard as to what discs will fit. @Rodders53 has given me the link, so now have the manual...

How far you go is up to you. In the 90s my son became a radio ham at 14, and I decided all should be RCD protected to protect him. My dad didn't and as a boy I did get some nasty belts, clearly didn't kill me, but to what extent one raps people in cotton wool is down to you. I would say...
