Looking at it, its fine at 450mm with 195mm so my 225's are golden.

really good point!! :D 4.9m.

What’s that? Thanks

Sounds like it….. however it looks like it’d just in the regs…..

got a roof we're doing, 45deg pitch, covered in slate(0.35 kN/m²) I've got 225x47(9x2) joists as a clear span. I was going for 400mm centres, would 450mm still pass regs? I'll double the rafters at velux windows. any thoughts/opinions?

Thats a major point, second being that I can bury all the power cables underground from the pole.

As that's what i've had some prices for. I'm as above i'm working out the realistic costs/whats involved of having a 3phase supply put in then how that alone knocks onto other things. I'm not running around wiring up old ladies houses in 1.5mm T+E.

xlpe, 16mm csa, 18m run, less than 4v drop when clipped so fagpacket maths says 72Amps

Hi John Looking at it, I may as well put in new 16mm swa to feed the house off the 3 phase(proposed) distro behind the garage. it'd only be a 18M run.

I'm just doing the donkey work, I need to work out costs/hassle agaisnst the plus of 3 phase. also finding the route!

It might make more sense just to run some new 16mm CSA cable given its cost.

Nope, a new 3 phase supply to a meter box(side of garage), then the 10MM SWA that runs from the garage to house will become the main supply cable for the house. Garage is the only 3 phase usage area.

I've a 10mm 4 core SWA cable that feeds my garage. I'm going to get a new 3 phase supply put in. If this becomes the cable to feed my house(10mm 4 core), can I use the '4th' core to increase the CCC of the cable? Ie,10mm CSA effectively becomes 20mm CSA on the live? I'd guess if possible...
