Requirements 15 Amps
Other countries: 90–264 VAC, fused at 10 Amps
■ Outlet must not be controlled by an on/off switch
■ Grounding to comply with Underwriters Laboratories (UL) 1459:
A. An insulated grounding conductor that is not smaller in size and equivalent in insulation
material and thickness to the grounded and ungrounded branch circuit supply conductors,
except that it is green with or without one or more yellow stripes, is to be installed as part of the
circuit that supplies the product or system.
B. The grounding conductor mentioned in item A is to be connected to ground at the service
equipment.
C. The attachment-plug receptacles in the vicinity of the product or system are all to be of a
grounding type, and the grounding conductors serving these receptacles are to be connected
to earth ground at the service equipment.
