£50 !! Shocking

Because it doesn't add anything to safety really. This is more about convenience. In the USA they don't even sleeve the earth, although it now is in the UK as there is the danger that when a socket or switch is pushed into the box that a bare CPC could contact a live part (more a nuisance due to the trip then a danger). If the insulation on the line and neutral conductors starts breaking down in T&E cable, then having an extra layer of insulation on the CPC isn't going to add any safety. That cable is already potentially hazardous and in need of replacement. All that will happen is you will find out about it rather later if the CPC is insulated. As to the reason, the CPC isn't insulated, then it's going to be down to cost and bulk. This new cable has thinned down insulation using a different material, but it's going to be more expensive. However, as installation is now the biggest cost of all, then it's likely to gain traction as it saves one small part of the time required.

That how I was taught to strip TW&E when I was at college 1987 - 1992

To the way I do it

Thanks for the feedback

Great comment 👍🏻

They look like they may just fit

There is no need to have a full sized CPC. Can you Aussies not do the calculations? The sizing is all based on the time required for a fault current to trip a breaker or fuse. Wasting copper is not clever, it's dumb.

In Aus your external sockets are literally just pointed down so rain doesn't get in them. When will you guys catch up with correct ingress protection?

@iedlos687 What on earth do you mean by "straight down"? Does that mean the plugs are inserted from underneath? That sounds extremely odd. In any event, external sockets in the UK are mounted in IP66 rated enclosures and, trust us, we do know about rain. In addition, it must be a sad old life when you don't have much else to do but to go around trolling others electrical standards. nb. I have now looked at some images of outdoor Australian sockets, and there are some angled down at 45 degrees (not straight down), and they would not be permitted in the UK as the whole thing is not in an IP66 rated enclosure. Also, not all of them point downwards. I can see images of some let into walls but at a normal angle. There is a weatherproof flap covering the actual socke (which is mounted vertically as normal). When the flap is open, the socket is exposed which is fine in the dry, but it affords no protectionto either the socke or plug if it starts raining. UK outdoor IP66 rated sockets have a waterproof cover that closes down over the plug and socket combination with the cable exiting from the bottom via a rubber gasket providing protection to both the plug and socket if it starts raining. I suggest you look at some of them.

@@TheEulerID there is no need technicly .. but still regulations in a lot of countrys require it ( most of europe belgium/holland/germany all our cables have same diameter CPC only for verry large cable the CPC can be half of the live conductor . for example on 120mm² cables we can use a 70mm² CPC .. ) Using this twinearth in Belgium would not be approved .. cpc to small / and cables a probably not CCA ( fire rating ) It's a bit of pitty why not 1 standard cable we can use EVERYWHE in Europe . we also don't have flat cables anymore like in de 70's .. all round cable here for fixed installation . Also fine stranded is only allowed in the fuse board .

Thanks 👍🏻

Not sure of this? IEC 60364 outlines two methods for sizing the earth conductor (adiabatic and simplified). If you calculate the adiabatic method, you can use smaller conductors even when under 16mm2

We tend to use British standard so BS6004

Almost same rules in Belgium .. we can not use this type of cable the cpc must be same size idd .

cost...

Probably if its popular enough, like im still waiting on seeing if MK make any other lever style connections for their accessories, but looks like the sockets are a bit too expensive and not popular

​@pn8902 I think switches and ceiling roses would be best as a lever terminal, and controversially I think MCB/RCBO should be. If we have to torque them to a certain spec, why not make them spring loaded so we can't get it wrong

@@darylsavage119what are you nuts .

@Dog-whisperer7494 that's why I said controversial 😂

@@darylsavage119Many other countries are already using it for their protective devices (bar the main incoming tails) and their entire accessory lineup, I'm with you mate, we're back in the times with the crappy flatheads

70 👍🏻

It's PVC

Shouldn't matter, I doubt you will be using anything on the end rated to 90 degrees

Good question..

maybe if the price of copper comes down...........

I don't think they're claiming they've invented anything new, my friend. They're probably just excited they've "caught up" as you would say. Although, the CPC being already sleeved adds no safety features - it's PURELY for convenience. I've never understood this weird superiority complex that sparkies have against other countries, wherever they're from, lol
