With either 2-phase or 3-phase, appliances which need 120V are
attached to one phase and a neutral. With 2-phase, appliances which
need 240V are attached to both phases. With 3-phase, appliances which
need 208V are attached to any two phases (dig out your trigonometry to
figure out where the 208V comes from). Three-phase motors are more
complicated ...

Wrong. Don't give up your day job.

Completely wrong. Stick to jerking off and leave the electrical to guys who
know about it.
