Imagine one man pushing a car up a hill; this is an example of single-phase power. So in order to provide a three phase they will do a split phase using two transformers and provide you with a delta, or the three phase with 120V to ground on two phases and 240V to ground on the other. It would be rare to not have 220 volts coming into the the top of the panel so if your panel has 220 volts, with a Static or dynamic phase converter you could run a 3 phase machine with only single phase power coming in. The voltage between two lines (for example 'L1' and 'L2') is called the line to line (or phase to phase) voltage. The large motor you refer to is most likely a single phase motor. Current (I): Enter the the current in Amperes (A). Let’s look at a simplified example of how 3 phase power is generated. Also, for a single meter, less than 7.5kw (10HP) load should be installed, particularly in domestic areas. (Black rectangle on the bottom right) Three Phase. If you have eight reasonably thick cables connecting to the meter, four of which go to your consumer unit or fuse-board, and your main circuit breaker has 3 or 4 sections with one operating lever working all three or four – known as a 3-pole or 4-pole linked MCB, then you have a three-phase supply. If on the other hand you read something OTHER than 277V (nominal) phase to ground, that would indicate it is NOT a solidly grounded Wye secondary. If its in a commercial building how many wires are coming to the mast above your meter socket,are they marked with differant colors like black/red/blue or maybe brown /orange/yellow?
