A short power-supply cord (or detachable power-supply cord) is to be
provided to reduce risks resulting from becoming entangled in or tripping
over a longer cord.
Longer detachable power-supply cords or extension cords are available
and may used if care is exercised in their use.
If a long detachable power-supply cord or extension cord is used,
The marked electrical rating of the detachable power-supply cord or
extension cord should be at least as great as the electrical rating of the
appliance
If the appliance is of the grounded type, the extension cord should be a
grounding-type 3-wire cord, and
The longer cord should be arranged so that it will not drape over the
counter top or table top where it can be pulled on by children or tripped
over.
