Garden cable

[BenStiller]

Got a garden run of 30m, will twin+earth suffice if there is no possible chance of mechanical damage?
Did a calc on tlc, reckon 6mm will do to supply about 5kw, any suggestions

how do you plan on protecting it? if you gonna use 25mm steel conduit.... prob just as much to use SWA

and remember: conduit isnt flexible

maybe if its hidden under a lip on a wall or something out of the way of both direct sunlight and mechanical damage T&E would be ok but SWA is certainly the norm for outdoor runs.

split con may be an option if you can get it but from what i gather it can be a little tricky to terminate if your not used to it (it is a lot cheaper than SWA though)

split con is easy to terminate?

ye i gotta see job tomoz, i was thinkin swa anyway, fella reckons wont need it, but we shall see

If the fella knows how to do it himself, why bother?. If he wants it done to his spec get him to sign for the design on the cert, then put the departures when doing the inpection and test and you will be covered.

went down to that job today...
He actually thought i could take a spare from the ring and run it about 25 metres to shed, buried in a shallow channel in garden, even though he said he wants power to feed pondpump and a birdbath (yes i thought that as well).

shallow channel in flower area was it? somewhere ready to be cut thru?

 

[breezer]

to the man in the street, it seems reasonable to take a supply from existing sockets, bury it in in flower bed use same cable as used in hose.

I am not sticking up for any one, its just that we know better, did you expalin why it can not be done as he wanted / thought

 

[BenStiller]

well for one, he had no rcd protection in very old fusebox, not even a spare way for the new radial circuit, 2, you had to come from the front of a very big house to meet swa in rear, you had to get cable over a paved area, and then your faced with a wall to get cable over/under/through...
next the shed is actually lying on top of a concrete base, and all this to power a pondpump and birdbath, im gonna call him tomorrow...

PS i did explain

You don't need a new radial - the load you describe could perfectly well be served by a spur from an RCD FCU on a socket circuit. Still needs SWA of course, at the proper depths..

2, you had to come from the front of a very big house to meet swa in rear,

Surely there are sockets at the rear of the house?

you had to get cable over a paved area, and then your faced with a wall to get cable over/under/through...next the shed is actually lying on top of a concrete base,

You don't have to bury the cable - overhead is a acceptable route too, you know..

 

[BenStiller]

Soz ban, forgot to mention, he also wanted a double socket in case anything else decides to go in the shed

As long as he understands that whatever he has out there can't add up to more than 13A....
