TooMuchAbstraction posted:So you still think it's necessary to vent the soffits even when their "airspace" or whatever is connected to the rest of the interior? Soffit vents aren't for the sake of the soffit space; they're for ventilating the rest of the space under the roof. There's no functional need for venting in an uninsulated, unconditioned structure, although you may end up wanting to do something (venting or a radiant barrier) to control heat on hot, sunny days.

Ferremit posted:220v/50hz single phase in Australia, so our we get a lot more bang for buck out of our amps. In the US, our main service is split phase 240v, so your 65A service has basically the same capacity as a 60A service in the US (which hasn't been standard since the '50s or so). Three phases of that would be on par with the 200A service that's common these days... so that is pretty crazy if you need more to run your AC. Also kind of weird that you add a 400v service instead of just upgrading to 100A.

Oh I see, I misunderstood. So it's a delta wye with 220v phase to neutral and 400v phase to phase. I kind of assumed you'd jump to a 3 phase compressor motor from there, but I guess since most residential equipment is single phase you get better economies of scale if you stick to single phase but at a higher voltage.
