Unfortunately "public charging" tends to be a lot more expensive than residential charging. There are a number of reasons for this. A small part of the reason is taxes, electricity for domestic purposes has a VAT rate of 5%, whereas electrcity not for domestic purposes has a VAT rate of 20%. An...

Certainly the LED tubes I've seen have come with instructions on how to wire the fitting for direct mains operation and say that you must do that if the fitting originally had an electronic ballast.

That is a triple row grid box. Unfortunately BG don't give screw hole locations for their boxes or plates, but the overall height of the plate is. single row - 86mm Dual-row euro - 186mm Dual-row combination 13A/Euro - 186mm Dual-row grid - 147mm Triple-row grid - 207mm...

I can see why they would want to phase out cables without proper overload protection inside buildings, especially in this era of EV chargers and suchlike.

I'd bet most likely someone took them home from work, maybe a clear out where they were otherwise going to be thrown away maybe outright nicked.

Is there really a big enough market for MK toughplugs that these are likely to be fakes rather than just items someone found in a clearout?

At least for ICE cars my understanding is that the regulations get increasingly difficult to meet, even if you are only trying to meet one set of them. Possibly less of an issue for EVs. Tarriff issues have also come into play, my understanding is that most cars for the US market are made in...

Car makers have to produce different variants to meet legal requirements and customer expectations in different markets. US spec cars and EU spec cars tend to be very different due to a battery of different legal requirements and are also often built in different factories. UK spec cars are...

What's wrong with MK toughplugs?

It's not particularly abnormal. In this country "twin and earth" cable has a bare earth wire, and the "done thing" is to sleeve it at terminations to identify it as an earth wire, and to reduce the risk of accidental contact with live parts, but the sleeving and/or the cable often moves around a...

Need to make more measurements to be sure, but my first suspect would be that the earthing of the dishwasher has gone bad, either in the dishwasher itself or in the circuit feeding it).

My understanding was that the wire used in "knob and tube" was insulated, but only with a single layer, which noone realy trusted (and may have degraded to nothing by now). The "knobs" and "tubes" then effectively provided a secondary insulation.

By "superficial inspection", I mean an inspection of what can be seen without dismantling. By "intrusive inspection" I mean an inspection that requires removal of covers, pulling accessories away from their boxes and similar actions. Some defects are obvious enough that even a superficial...

However, as I said earlier in a typical EICR most of the installation only gets a superficial inspection. IMO if the intrusive inspection of a sample finds a significant number of faults then the electrician should be recommanding to the customer that a 100% intrusive inspection is undertaken...

My understanding is that 100% intrusive inspection is not the "done thing" on a EICR. The "done thing" is a superficial inspection of the entire installation, plus an intrusive inspection of a sample of points, plus testing between the origin and furthest point of each circuit. So directing a...

I generally understood that "down is on" is the traditional british convention, while "down is off" is the IEC convention. As switchgear has been harmonised, but wiring accessories have not this leads to practically all british premises having a mixture of the two conventions.

They might well use a 4 pin or 5 pin connector for commonality with other equipment, but I can't see how there would be anything wrong with using a 3 pin. Just as it's not wrong for us to use 3 pin yellow connectors for construction site supplies.

Ah how time flies. AIUI grey came in around 2004, as part of the negotiations to finally bring the UK fully onto the harmonised colours.

My theory is that MK hope that specifiers will only compare the "basic" products and won't notice the high prices of the more unusual products until it's already too late. Either that or they think the kind of people who buy media plates are the kind of people who will specify MK no matter the cost.

My guess is they are attempting to snag the affiliate revenue, and screwing it up.
