Running a new SWA to supply a shed

[Helm-Electric]

Running a 4mm SWA to the shed, approx distance is 20m. Earthing is PME.

I plan to run the 4mm SWA out from the wall of the house and cleat it along the side until it reaches the back of the house. From there the cable will go to ground at a depth of 450mm all the way to the shed. I plan to fit a 2 way CU for lights and a double socket within the SHED. The SWA will be protected by 30mA RCD and MCCB at the CU within the house. Total load shall not exceed 2kW. The installation will be inspected and tested by qualified electrician who also happens to be my friend. I am making it easier for him by doing all the grunt work...

I am guessing there is no height restriction for the SWA?

Thanks

You may find with luck that it is an high integrity board and may have the 3rd Neutral bar, if it's a common make you may if it hasn't get a adapt kit to create it.

It really is better to have your RCD local if possible, especially for an outside installation. It become quite a chew in mid winter, to loose power and light, when your 20mts from the house and scrabbling about in a dark shed and garden, plus Doris might get miffed with the house being taken out.

Whats my dog got to do with it?

WHY do you keep refering to MCCB???

I realy worry about the "cable under stones in a plastic pipe" ffs No wonder DNOs are in the state they are if you are an "Engineer"

In Cornwall we make the rules up as we go along and call things what we like

You don't even need to be 'qualified' to be a spark down here.... All you need to know is how to wire a plug and change a light bulb.....
