Re: [TCML] 3 Phase Power
Typically with Australian 240V 50Hz systems, the phase to neutral is 240V at
32A per outlet leg. Each leg would have a breaker as I understand.
For a recent show I needed 60A plus, so I plugged into two 3 phase outlets
which were 5m apart. I used a switch to connect the red phases in parallel
to increase the potential output current available before breakers trip. I
have a light (two in series for 500V) to indicate if the phases are not
correct before linking them. This is not really legal or safe but worked
fine for me. Theoretically I could draw 15kW with this arrangement.
It should work on large generators as well that have two or more plugs
together.
Carlos at Lords of Lightning uses a transformer wound for 415V so he can use
the voltage across two phases. On a single plug this would give 12kW which
is only half what he needs so it is wired directly for 25kW plus as I
understand.

Than
no. You'll just be running off one of the phases. What voltage is your
coil set up for?
How is your 3 phase power provided? two popular ways in the US are:
208/120Y - called Wye or Star: it has an explicit neutral. the phase to
phase voltage is 208V and the phase to neutral voltage is 120V. Your 120V
coil will run from one of the phases to neutral.
240 delta - 240V between phases, no neutral. you'll either need a step
down from 240 to 120, or if you've got a system where there's a neutral on
the midpoint of one of the phases, then you you run your 120V load from
phase to neutral.
If you're running a pole pig system, then you'll probably just run it off
the 240V.
