    SWA For meter tails?

    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.

    SWA For meter tails?

    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...

    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.

    Radials are sockets in Garage, workshop & new utility room. Upstairs & downstairs are existing rings - don't really want to add work by converting to radials if I can avoid. Splitting kitchen off downstairs ring onto its own.

    House+garage+workshop: Starting with 7.4Kw Induction Hob (1st 10A plus 30% of the remainder) 16.6A already... 3Kw Immersion heater - No Diversity allowed another 13A... 3Ring + 3 Radial Circuits (100% of 1st & 40% of rest) 32+49.6 = 81.6A + 4 x 6A lighting - haven't worked out all the lights...

    Give a guy a break. If you looked at my profile you would see I'm a qualified electrician but still very new to the trade. I thought this forum was here to help people like me who are still learning, rather than knock us down. If people can't be open and ask questions that might show they are...

    Not an option given I'm struggling to get diversity calcs down to 100A and I already have 16mm tails anyway.

    Thanks for the link. That's the cable I looked at first, but doesn't OD stand for outside diameter? How can that be 25mm if the individual cores are 25mm?

    DNO replace the fuse, but they won't do the tails to the CU.

    No seals being broken. I had an isolator fitted by my provider in anticipation, I'm not aware of it being fused however.

    My main fuse is due to be upgraded to 100A due to an extension project that involves an induction hob. Actually with my diversity calcs, I'm struggling to get it down to 100...

    SWA For meter tails?

    Yes I was wondering about cable enclosure if I don't use SWA. Seemingly 25mm Conduit can be used, according to the cable factors. 16mm factor = 145 25mm Cable factor = 217 2x217 = 434 Total = 589 But I can't quite see how two 25mm cables fit in a 25mm pipe? Maybe something about the size of the...
