	Subject - Three phase power trotter Need some help with three phase power. If a piece of equipment is rated to pull in 12 amps at peak performance level with three phase power is 12 amps being drawn through each phase? Or is a total of 12 amps being drawn between the phases? If not 12 amps per phases is there a way to calculate how many amps per phase is being drawn? That same piece of equipment is rated for 19 amps using single phase L-L. Does that mean it's pulling in 8 amps per phases for L-L? Thanks for your help on this? Scott Vickrey In the case of the 3 phase each ungrounded conductor or hot wire will be drawing 12 amps. In the case of the single phase each ungrounded conductor or hot wire will be drawing 19 amps. I hope that answered your question. trotter Yes, that answers my question. Thank you. gregm the power produced in watts in a single phase circuit is the amps times the volts. In three phase it is amps times volts times the square root of three (~1.73), so a piece of equipment that is a given voltage three phase will only pull 58% of the amperage of a single phase unit, same voltage and wattage assumed.
