    Open Delta Connection - part 2

    I have encountered an open delta 3-phase 240V service in PA and have been confused by so many different explanations. I understand the B (high or stinger leg) is at 208V to ground. Can a single pole breaker then be used (if connected to the B phase bus) to power a 208V piece of equipment?

    Open Delta Load Calculations

    Just another question, can I use a single pole breaker to serve a 208V, 1-phase load as long as it is on the B (high leg)?

    Open Delta Load Calculations

    I have encountered an open delta 3-phase 240V service in PA and have been confused by so many different explanations. I understand the B (high or stinger leg) is at 208V to ground, but are the phase to phase voltages still 240V and this is how they get the 3-phase loads from this system?
