SWA For meter tails?

[Msitekkie]

Think of peak times morning evenings when most load will be consumed should only be short periods when applying diversity,
a bs88-3 (new bs number for 1361) will take 190a for half hour fig 3A1 bs1761

Thanks for that. Fig 3A1(page 319) is most illuminating. Few discussions of diversity refer directly to this time factor and its clearly very relevant.

That is a bit of a lash up, what you want is a bit of swa cable

Could the tails be routed out the back of the meter box, then surface inside in some plastic trunking?

I would consider using a 16mm split concentric chopped in the wall Covered by an earthed 3mmsteel plate covering, from the incomer connected to a kmf isolator

If it's SWA why would I use surface trunking? The problem I'm facing really, is once it reaches the porch getting it through the brickwork and wooden beam to the void. Ironically the supply to the meter appears to originate from somewhere under the concrete floor inside the porch, but moving the meter inside isn't really an option.

Trunking looks a little nicer than cleated SWA.

To get through the brickwork and wood drill a hole.

It’s not really ironic, it’s just probably been moved outside from it’s original location inside.

Why is it Old Lee?

I was suggesting an alternate to swa, some 6181y and surface plastic trunking?

OK. Yes, looks like this is the way I'm going to go, then straight through the wall and cut a channel round the outside of the brick pillar (inside the porch), through into the void.

When you say cut a channel you don’t mean to bury the tails in the wall do you? Because then they’d need RCD protection which would be unacceptable.

In conduit.

How will you Earth the conduit?

How will you Earth the conduit?

Plastic conduit.

Plastic conduit.

Really ? Please refer to previous comments of concern suggesting you get an electrician in.

I am involving another electrician... As mentioned previously. Existing tails are in plastic conduit embedded in the wall. This is more like passing through the wall in conduit as does the DNO supply.
If you have feedback on the method based on standards, please refer.
