People outdoors will also "virtually always" be wearing footwear. I think the key difference between outdoors and a garage is the potential for water in sufficient quantities to overtop or soak-through footwear.

BT was trying to force everyone onto "digital voice" services where the voice traffic is carried using VOIP over the customer's broadband connection, but evidently that is not working out or at least not as quickly as they would have liked. Moving voice onto the fiber to the cabinet...

Generally, ground/floors are not bonded. It is not impossible to bond them, but it's expensive and rarely done in domestic situation. Indoors floors are usually dry and hard, and in potentially wet areas are often surfaced with non-confuctive materials like vinyl. There is often another...

There are various approaches to making a class II device. One is simply to put "double/reinforced insulation" between everything electrical and everything a user can touch. That is fine for something like a lawnmower but gets tricky for bigger stuff. Maybe it could be made to work for an...

We hapilly protect 4mm² T&E which has a 1.5mm² CPC with 32A breakers. So I'd be rather surprised if a 32A breaker did not provide adequate short-circuit protection for 1.5mm² flex (to be 100% sure you would need "let through" data for the breakers which seems surprisingly difficult to find)...

It's very difficult to be sure a supply is TN-S unless you have a private transformer. You can't tell for 100% sure whether it's seperate in your supply cable without opening the cutout, and even if it's separate in your supply cable, it may be combined further upstream. The fact the results...

Counties are messy AIUI you have The "historic counties" that existed pre 1970s. I don't think they have a lot of modern practical/beuracratic use, but centuries old traditions don't dissapear overnight. The "ceremonial counties" defined in the 1960s and 1970s used for the monarchs...

Easy enough to play it off as a mistake, or claim it was like that when they got there (at which point it would be the inspectors word vs the tennants)

Hmm, I don't see any "current sense" pins on the type 2 pinout (the most common EV charging connector today) Just L1, L2, L3, N, PE CP and PP.

I've seen a few approaches. Your typical "granny lead" with a 13A plug will just signal a fixed 10 amp maximum. Units with 32A plugs will often have some kind of buttons to adjust the max charge current. The information on max charge rate is sent to the car by varying the duty cycle of the...

Yes The "charge point", whether fixed on a wall or part or a portable cable tells the car how much current it is allowed to draw.

Indeed. Which is the point of supplemntary bonding, the supplementary bonding conductors are much shorter than the CPCs. So the 'touch voltage' between bonded objects is much lower than it would be with CPCs alone.

Are they saying you can use it to clamp one pin of a plug.

Would "only" be a C2 at-least according to the "electricial safety first" guidance.

I guess ultimately this brings us to the other requirement, that sustained overloading should be unlikely. Would/should you as an installer do more to convince yourself that sustained overloading was unlikely if you were installing a ring with an installation method that resulted in a 20A...

I don't see how installing a ring circuit with a '20A-rated' connector is fundamentally different from installing a ring circuit where part of the cable is installed with a more restrictive installion method than the rest such that the CCC of that particular section is only 20A.

In the video he essentially states two things. One of which he backs up with a reference and one of which he doesn't. He states that according BS7671 the cable for a ring should be rated at at-least 20A and gives a reference to back it up. He then goes on to state that the same rule should be...

Two independent faults in two different circuits within a second of each other would indeed be extremely unlikely. The harder question is how plausible is it for there to be two "live-cpc" faults on different circuits with a "common cause". I would think the only remotely plausible situations...

Harmonised colours for fixed wiring in the UK were introduced in 2004, with a two year transition period, so red/black was considered "acceptable"* until 2006. Of course what was acceptable and what was actually available can be different things. I presume the suppliers wanted to phase out...

Lots of things are sold that could be unsafe if misused. There will always be a compromise between protecting idiots from themselves, and not preventing the sale of useful products. Afaict the requirements for fusing in BS1363 have remained largely unchanged for a very long time (possibly since...
