Adding a second outdoor socket

[quinny100]

My house was built in 2015 and I have a double outdoor socket on the back wall fed from its own 20A MCB in the consumer unit using 2.5MM cable, radial circuit.

Can I run a cable from the existing socket terminals, out through a gland and on to a second outdoor socket at the side of the house? I'd use 2.5MM cable, probably Hi Tuff clipped to the wall of the house quite low down. I'd get a decent socket like an MK.

I need a socket next to the driveway to charge my C350e which is arriving shortly. It'll pull 8A for 3 hours at a time worst case, but I'll reduce the charge rate below this the vast majority of the time because the car will be sat at least 12 hours overnight if I'm at home.

I don't really want a charge point on the side of the house as the driveway is narrow enough as it is, I don't want to run another cable from the CU as its situated under the stairs right in the centre of the house so the cable routing would be problematic.

The theorys sound, is it RCD protected?

Prefer FP type cable for clipping myself as its less inclined to sag, buts thats just cosmetic, mk not worth paying more for than BG these days. Use bottom entry holes wherever possible and avoid top entry for best water-proof-ness.

[Andehh]

This is where I admit to doing exactly that, and hope it doesn't turn out to be the worst thing since Pompeii!

Use swa.

It is easier to install and will look tidier fixed along the mortar line.

And don't forget the minor works certifcate when you are done.

I doubt a Diyer would manage to install SWA correctly. (Most seem to just chop the armour!)

However would agree SWA or conduit looks much better than badly clipped cable.

It is RCD protected.

I'll probably get a spark to do it - the estate is still being built so there's always a few around.

Just wanted to verify it was feasible, otherwise I'd look at getting a charge point run from the meter cupboard outside. Any work inside the house is strictly forbidden by the OH.
