Can someone please tell me what the difference is between single phase power and 3 phase power?
The pros/cons?
Where 3 phase is needed?
The cost difference?
Thanks

The builder attempted to charge us more as this was an extra over the standard 10amps. When indicated an induction has always been specified, he said that the model we had chosen was not a standard, and that he'd run 20 amps to his, and that he'd contact the electrician and make sure he wasn't "going overboard". I have no idea what was installed 10, 20 or 32, but we cannot put more than one section on max power at a time. Would this have to do with the amps run? In relation to the phase, in our tender a 3 phase was included, but we only a single phase was done. We have had issues with other electrical work being incomplete and this is part of it. Does only having single phase impact on the induction? If not, then it doesn't sou d like we need 3 phase, but given that it's more expensive, we then should have received a credit for this - but for how much I have no idea. Thanks for your replies so far....I am completely lost with all of this so thank you for your patience with me Re: single phase and 3 phase power 13Mar 14, 2012 11:05 pm Apart from the extra power, another reason for 3 phase is smoother power delivery as the alternating current waves from the 3 lines are out of phase (sync), hence the name, and thus sort of "fill in the gaps" reducing the depths of the peaks and troughs of the waves. This is why 3 phase air conditioners dont need soft starters. In a residential setting though its usually just for extra power for big aircons, welders, pool pumps etc. These have to be specially wired up though. What normally happens is they split the house wiring circuits for power points etc across the 3 phases so that you are still just running on a single phase for everything else. This is why powerpoint based networking and intercom devices say the are not compatible with 3 phase. Technically they will work but only if both ends happen to be on the same phase circuit and typically you can only find that out by trial and error. In regards to the cooktop, I would not expect 3 phase unless it is commercial grade (which is perhaps less unusual these days). I wouldnt have thought that any sparkie worth his salt would wire up a 3 phase device to single phase. Re: single phase and 3 phase power 14Mar 16, 2012 11:17 am We will be getting 3 phase as we intend of having an outdoor spa, ducted reverse air conditioner and our house is going to be big so to run all of this with the normal appliances we will require 3 phase power to handle the load.

Hope you dont mind paying the big bills Yes I know even with the solar panels we are going to put in it is going to be expensive! As we are going to be within walking distance from the beach I'm hoping the sea breeze will help during summer! 1 62110 Hello All 🙂 We are planning to start our journey of construction our first home.
