Totally not relevant to this thread, but last year I worked in a house where the elderly customer was frequently recording TV programs in the day to watch when she got back in from the farm in the evenings on a Philips V2000 machine. I instantly recognised the design of the tapes, of which there...

An adaptable box is designed to be adapted, a normal domestic consumer unit probably isn't? Though I've always argued if it has a DIN rail in it you should be able to install DIN mount devices. Yes sometimes care has to be taken with spacing for airflow around contactors, but a small lightly...

Here is a thermal image I took during a recent call out. The cylinder is fairly tall so the top entry element only gets about half way down. This is on the ground floor and the cylinder almost touches the ceiling, to replace the element you have to take the carpet and floorboards up above. The...

The Ring doorbell PSU supplied with some Ring doorbells, or available separately from Ring, fits a single DIN module way. Though there are arguments saying products not type tested by the consumer unit manufacturer shouldn't be fitted in the consumer unit. Ring also make a matching surface...

Your post wasn't there when I replied!

Probably the tap on the transformer!

The flex will be a short section from a connection point to the photocell, the cpc will be available there.

I keep 3 core flex on the van that has brown black and blue cores for photocells.

The heated water doesn't go up the expansion pipe (ok the level might rise a bit) the cool water comes from the cylinder not the cold water feed tank, there will be no flow from the cold tank unless a tap is opened. thermosyphon is surprisingly effective, and the water will have no problems...

The heated water will rise up through the heater via thermosyphon, as it does it draws cooler water from the bottom of the cylinder, heating the cylinder from the top down.

Older MEM MCCBs are known for never being able to switch them back on again after they have been switched off. A colleague tripped a 400A(!) Dorman Smith MCCB a while back. We couldn't reset it until it was dismantled and the mechanism freed. The grease used on the moving parts had turned to...

No not isolated. Most people just use their mobile phones for everything and have now ditched the landline phone. I have FTTC internet. Though one of the neighbors accidentally booked full fiber to my house instead of theirs, so I've had a coil of unterminated fiber cable outside the front door...

I was moved to BT's 'digital voice' mid last year. No warning, I phoned up to report no phone service only to be told I had been switched over! The new service has been most unreliable, frequently can't dial out, just get error message instead of dial tone, the audio quality is really harsh and...

I have this very old NOS MK plug and socket. Even back then they are calling it a socket and plug.

It's not straight to allow the water to run off.

The photo of the cutout suggests a TN-S earthing system not TN-C-S.

Perhaps you should have had a better sparky out... There is no reason the fault could not have been narrowed down. MCB or pump sounds like clueless guesswork to me.

The main danger is to someone working on the circuit the neutral has been 'borrowed' from. If someone was to isolate the socket circuit, test it dead, it would appear dead. If they then disconnected the neutral wires at some point on the circuit between the consumer unit and the light, say to...

As above. Do you have 240v on the grey wire too?

The one in jj4091s link was closer than mine...
