What does 240 volt hard wiring mean?
It means that the 240 volts is connected directly to the device
rather than being connected through an outlet. In some cases an
electric box may be wired between the power supply and device and
could contain fuses, breakers or a disconnect of some type. For
example if you have an outside air conditioner there should be a
disconnect box on a wall near the unit. The unit would still be
considered to be hard-wired.
