It looks like all the switches are already being used as two way. You could swap one of the modules for an intermediate, but if you are going to swap modules, I think putting in a double-wide two-way module makes far sense. Part number is MD024xx where xx is the finish you want. I'm not going...

Yeah, they are fine as long as they are in a suitable enclosure and are accessible for inspection. If they are not accessible for inspection, the enclosure and terminals must be approved in combination as a "maintinance free junction box".

For domestic cooking equipment the diversitiy guidelines say first 10 amps + 30% of the remainder + 5A if there is a socket. We can work that backwards to work out the maximum cooking load for a given circuit. With socket: ((i-10-5)/0.3 + 10) * 230 Without socket: ((i-10)/0.3 + 10) * 230 32A...

Looking back at your first picture, I see a logo in the middle of the switch modules, I think it says scholmore in curved text, but I can't be 100% sure.

That looks like Scholmore Click stuff, if so it's possible to replace one of the switches with a blank, or possiblly to transfer all the switches to a 3-module plate (though personally I think the 3 module plates for double boxes look a bit weird). IF you can tell us the part number of the...

Maybe some would have done it when earths first came in, old habbits die hard and all that, but earths have been required for decades now. The presense of brown/blue cable tells us that it was done in 2004 or later. It depends what's fed from the circuit past the point of the "breaks". If...

I used to know someone who owned a vintage military truck which was apparently very tolerant of what fuel you ran in it. Apparently he used to get fuel for free by asking garages for their waste fuel.

The problem is spring clamp connectors covered in heatshrink tubing are NOT on the list of acceptable methods for inaccesible joints in BS7671.

The cynic in me would suspect that it's high enough to be profitable for a dodgy electrican, but low enough that fighting it is likely to cost more than it saves.

This is not true, an "unsatisfactory" EICR can absoloutely be issued. On the other hand, this guy may have done you a favour by not issuing an EICR, because once an unsatisfactory report is issued then it starts a clock under the law. Sounds like BS to me. BS7671 requires consumer units to be...

IIRC the Americans do single phase charging at 60A, but I just can't see that becoming a thing here, our electrical supplies just aren't big enough to support it. Some vehicles do 3 phase charging, but you'd need to get the supply to your house upgraded to three phase for that, probably not...

The requirement in BS7671 applies to "points and acessories", the definition of accessory explicitly excludes current using equipment. So we come down to the definition of "point". IIRC a point is defined as something like "a termination of the fixed-wiring intended for connecting equipment" or...

Not really, just a matter of making things smaller/thinner. In the UK caravan parks, caravans, marinas and maybe some industrial scenarios spring to mind. And remember, din-rail mount devices are used across much of the world (basically everywhere except america), even if the UK market for...

A quick google suggests 16A standalone RCDs (not RCBOs) in din-rail format do exist.

There are at least two things to think about here. Firstly, what exactly do you mean by "RCB"? that's not a commonly used acronym! To comply with current standards, your socket circuit needs both overcurrent protection and RCD protection. * A "MCB" provides overcurrent protection. * A "RCD" or...

I can think of a few potential reasons for that. Firstly if a cable is highly loaded then Firstly, if a cable is consistently highly loaded for many years energy losses can significantly outweigh the cost of the cable. Lets say a cable carries 50A continuously for 50 years. Over it's lifetime...

ROFLMAO

Only the supplier can say for sure, but I don't see anything obviously wrong with them. The thinkness of the plastic and the set-back of the metal parts from the front face both look quite reasonable to me.

Another possible option, which does come with some risk but may be worth considering is to use the existing cable as a pull line to pull through a new longer cable.

Their website claims you need to own a heat pump or electric boiler to be eligable panel heaters don't seem to count :( Edit I was wrpmg, the main page only mentions electric boilers or heat pumps, but the faq says "If you have a heat pump (air or ground source), an electric boiler or electric...
