Frequently Asked Questions (and answers!)
Have I got single or 3-phase power supply?
Most customers have single phase power supply but some larger homes and businesses with big energy loads (such as for some ducted airconditioning systems, heat pumps, cool-room compressors etc) may have dual or 3-phase power supply. There are a number of ways to check. Here are the easiest:
* Call your electricity provider (Essential Energy, Energex, Ergon etc)
* Look in your meter box. How "poles" is your mains power switch?
