WebEveryone knows that 480v 3 phase will read 480v phase to phase and 277v phase to ground. Well at work we have a 3 phase system with the B phase slugged instead of fused. Reading phase to phase gives you 480v as expected, but when reading phase to ground you still get 480v. I can't understand how this works. Any insights? 13 Related Topics WebLine-to-line voltages in three phase systems are typically 1.732 times the phase-to-neutral voltages: In symmetrical three-phase electrical system, the phase-to-neutral voltages … blackmagic design braw plugin

It's typical to transform 480V down to a lower voltage, usually 120 or 24, because it's cheaper and easier to find controls for those lower levels. But if you have controls rated for 480V already in place, plus a contactor coil rated at 480, then you're pretty much good to go. And if you're going to step the control voltage down ... blackmagic design blackmagic web presenter 4k
