Please help us to settle an "argument" at home re what phase power we need for the new house! * Double storey house, around 40 sq. * Gas ducted heating (0.4 kw) * Evaporative air con (16.7 kw) * General power & lights (2 kw) * No downlights * No plasma tvs * Couple of computers * Couple of ceiling fans * Possible future single (small) inverter on wall downstairs in one particular spot (just thinking if we have another summer like 2009)... DH says we don't need 2 Phase or 3 Phase as we're not running a massive refrigerated aircon unit or any hardcore machinery. I'm thinking we probably do need 2 Phase, just because, well it seems like the right thing to do, planning for future possible requirements, etc. It seems like one of those things you should do at the time of the build because it will cost stacks to do later.

The 3 phase (415V) would only be needed for the air con, however the rest of your circuits would then be balanced across all 3 phases. To be sure, look up the specs of your air con (if you know the model). Hi JW I just read your post and I find this situation quite strange. When we build, we get a temp pole for construction which becomes the permanent pole for one of the… 1 3944 1 4086 DIY, Home Maintenance & Repair Hi everyone Question about Brevis gas heating undergound - was recently installed by previous owners (<1 year old) but live in a relatively large house - 4 bdr - and only… 0 1262 |
