:?:ashamed1:Hello to all first off. I am a commercial electrician and recently landed a job doing more industrial than commercial. Anyway, I do not understand three phase 240v... I get the wild leg B phase is high leg but I don't get how A to ground reads 120v, B - G reads 240volts, and C to ground is 120v. Its almost like single phase 240??...????????. How does a a 2 pole breaker get 240v when B phase is 240v?? Or a motor say wye example, 3 phase in peckerhead would be L1-a, L2-b, L3-c, 4-7, 5-8, 6-9.. How do I run 240v 3phase to motor??? Hope that isn't to confusing. I just can't wrap my head around this Delta. Thanks
