Hi,
Before going through the length and costly process of notifying Building Control of my planned garden work.
I was wondering if I could sound my idea on this forum, and see what everyone thinks.
I have a CU in my garage, that I am planning to use to run lighting into my garden.
The garage CU is run from a sub-main from the house CU, and is RCD protected by the house CU.
I was planning to put a new 6A MCB in the garage CU and run 2.5mm cable to a DP switch. I was then planning to use 2.5mm SWA from this switch to take the power outside, by clipping it to the garage and house walls to an adaptable box on the side of the house. The plan was then to use some additional SWA to take the live connection to a weatherproof light switch by the back door, and back to the box.
A further length of SWA would then take the power through existing ducting under the patio to the first garden light. I'd then daisy chain the cable around the garden to the other lights (9 in total) running it through ducting, which would be about a 50m of cable all in.
The ducting is already in place running to where the lights would go, and is about 2 foot deep, with the necessary warning labels over it.
The SWA would all be 3-core, and I'd use the black wire as the earth, and the grey wire as the neutral connections, and sheath them accordingly.
I'd also earth the armour in the SWA at each junction using a banjo attached to the SWA glands.
Is there anything obvious I'm planning to do wrong, or can anyone spot any issues what what I'm suggesting?
Feel free to be as merciless as you want in picking faults with the above, as the last thing I want to do is get torn a new one by building control after forking out for their insepction fees.
Thanks
Rich
