RCD not needed
The sea??And if installed correctly, the anything penetrating the sea is almost certainly going to take out the fuse ....
If the cable is less than 5mm below surface it has an earthed sheath as in conduit MICC ETCBecause?
I knew that Honestpoxy predictive text
SWA
So what do you think that tells you Leep82I agree with everything thats being said, but im obviously alone in thinking the T&E method has its benefits over the sheathed/insulated tails.
It doesnt tell me im wrong as its all opinion. No install method mentioned is a deviation from the Regs and nobody has said i shouldnt use T&E because of ........ My prefence would be SWA>T&E>insulated/sheathed tails, but it all depends on the installation.So what do you think that tells you Leep82

Whats a seal?
Yeah im not saying its by any means fool proof, i just feel theres more chance of striking more than just the one conductor when using a T&E
Without wanting to sound stupid what is tht earthed armour offering ?
Yes i agree, so by that token does a metal object have more chance of striking the CPC in a T&E than it does if using insulated/sheathed tails? Im not trying to argue against SWA, its the best method discussed on this thread. I was just asked what benefits a T&E would have over tails and for me this is it. Granted its by no means a certainty and as none of the install methods are not to current regulations it doesnt actually matter, but my personal opinion is the T&E method has advantages over 25mm tailsThat earthed armour is offering protection from electric shock for anyone damaging the cable with a metal object.
The point of having earthed armour on a cable is to connect any metal object which penetrates the cable to earth before it makes contact with any live conductor, this in turn ensures operation of the protective device.
It wont beApart from the use of SWA I think we are getting into the argument of good practice.This supply in "meter tails" should not be protected by the DNO protective device.
Would be my best case scenario too, if budget & circumstances allow.Would it not be better to extend the supply via SWA from a DP Switch Fuse?
Yea guys this is the best scenario however the 25mm tails are already in and ceilings boarded and skimmed. The debate has gone slightly off topic and benefits of other methods are being discussedWould be my best case scenario too, if budget & circumstances allow.
If the 25mm/16mm tail kit is in place (and there will be suitable DP switched fuse after the meter) I don't see a problem.

I dont think ive missed the point to be honest i fully get that. But neither the T&E method or insulated/sheathed tails offer any earthed metal work.You’ve missed the point, it is not about striking the cpc, it is about making contact with earthed metal first.
Yes there might be slightly more chance of hitting the cpc, but that’s no good if the metal object has gone through the live first and injured or killed the person holding it.
‘More chance’ doesn’t offer any protection at all.
