Cable method for sumerhouse power

captaincaveman · May 11, 2019

Hi guys,
I'm just looking over a job putting power to a summer house but am wondering if anyone has any recommendations on how to lay the cable.

The cable length from the house is 50M going up the house side wall, across a patio, up a 10m wall (onto a balcony garden) then across a balcony garden (through shrubbery and banking up at a 40 degree gradient) to the summer house. The garden is open to the neighbours gardens (so potential trip hazzard / eye sore) and there is a tree in the direct path of the cable meaning roots (so no trench).

I see 3 options: swa on cable tray on posts, t&e in rigid metal conduit on posts, t&e in flexible metal conduit on posts

If anyone has done similar and has an opinion would be appreciated?

This sounds like an interesting one. Can't wait to see what idea's come up.

Will the customer be happy with cable tray on posts or is that an eye sore, if it's not going round the edge of the property?
Any pics of proposed route? Hard to envisage route from description.

from the OP, i'd be looking at SWA. routing to be determined after a site visit.

I've lost count of how many times I have seen so called sparks just leaving swa laying on the earth/grass or clipped to wooden fences. I have lost many jobs where I refuse to do that.

I would only ever use swa and can't see any benefit to running singles or twin/earth in trunking.

standard modern install

See this all the time

SWA thrown in , the occasional cleat on every other fence post. Sometimes a bit of top Soil thrown over it for a pukka job...
Of course Not glanded properly , no earth connection on the armour.
