Trunking

[watson650]

Hi

Just looking for some advice. I've had a new supply and meter fitted on the outside of a building. The supply is for a new consumer on the first floor. The meter tails for this have been run down the outer wall. What trunking would you use to protect these?

Many thanks

What are the meter tails, what type of cable?

I'm not sure what size. The cable you normally use for meter tails but just longer dangling down the side of the building.

Think we used 2" x 2" galvanised for the boards incoming supply because they specified that. The electrician suggested some kind of metal cable guard for the tails but I have doubts.

I can take a photo but not for a day or two.

Whilst 6181y cable attached (has it been clipped?) to the side of a house above head height, and assuming it is 6181y cable, it's not the sort of cable suitable for outside IMO (UV damage etc). Think swa cable would have been more suitable. Have you asked your 'electrician', why he/she is recommending protection for the cables, but not actually installing it?

DNO supplies are of a different concern and specification, surprised they asked for galvanised trunking?

I think the idea behind the cable is once it is in trunking it's protected. He will be fitting the trunking/guard but will do that when he comes back to connect up etc.

Right?

Just use a plastic HDPE or PVC or metal cable guard/protector depending on the level of protection you will need. You see them a lot on the cables down posts from overhead cabling.

That's 'black' concentric cables used by DNO's ,not 6181y cables, lets wait for the pics first

I'd prefer to see SWA instead personally. I've never seen meter tails fitted outside and I wouldn't do it, but I'm struggling to think of a regulation it would contravene if contained within galvanised steel trunking.

522.3.1 stipulates it shall be erected so that no damage is caused by condensation or ingress of water.

Running a cable down a wall (contained or not) and straight into an enclosure is almost guaranteed to result in the ingress of water within the enclosure (unless of course it's protected by an appropriately IP rated gland - I don't think a plastic bag fits that description). Who knows where it's going to go once it's inside. I would have run it down the side, put a U at the bottom and then go back up into the bottom of the enclosure to create a drip point.

Nice to see someone taking a pride in their work. However you try and tidy that up, it'll still look what it is

Would of looked less unsightly & and a better job, had the cables been installed on the inside, in trunking.

I have to agree with others, that looks terrible and as @SparkyChick said it would have been better entering via the bottom.

Plastic bag stuffed in hole. Sorted.
