3. 220volts versus 120volts .........

High voltage has advantages. Its a more friendly world to work with.
Wires and circuits can be made lighter, smaller, and are easier to
manage.

I work with 480 volts. The wires going to a large load such as dozens
of lights or a motor are MUCH smaller using high voltage than low
voltage. The lower currents of the high voltage are less likely to
cause melting of poor connections.

Unfortunately, high voltage from 480 volts can flash over dirty
connections in high humidity. And a finger touching the wires can
cause interesting damage to the body, like blowing off fingertips.
