"480V is VERY dangerous," I have to agree with that. If its straight three phase three wire floating UnGrounDED DELTA, coming in contact with two legs at the same time IS SURE DANGEROUS and 480 volts worth.

If its a GrounDED 480Y 277 V Three Phase Four Wire system, coming in contact with one hot phase and ground (fairly easy to do if inexperienced or wreckless) yields 277 volts STILL DANGEROUS while coming in contact with two hot phase legs would be needed to get the full 480 MORE DANGEROUS Yikes

EITHER 277 OR 480 CAN SORTA RUIN YOUR DAY, BE HAZARDOUS TO YOUR HEALTH AND CAUSE YOU TO WAKE UP DEADDDDDDDDDDD
