Dan,
You do understand that 240 volts ( in the USA) is erally only two 120
volt circuits?
Touching either wire, only gives you 120 volts, to ground.
480 volts, is really 277 volts to ground for any one of the three
wires. 480 volts between any two wires.

Now, 277 volts will not be anything I ever want to experience!

Are you sure that is true for all 480v systems in the US?

I think all three of my phases measure 480 to ground, and 480 phase to
phase.
