by the EPA for energy-efficient computers. |
UL
For computers set at 115 V  Use a UL-certified grounded cable, type SVT or
SJT, with a minimum of 18 American wire gauge (AWG). The cable must be no
longer than 15 feet and must have a parallel-blade, grounded plug rated for
15 A.
For computers set at 230 V (within the U.S.) Use a UL-certified grounded
cable, type SVT or SJT, with a minimum of 18 AWG. The cable must be no longer
than 15 feet and must have a tandem-blade, grounded plug rated for 15 A/250 V.
For computers set at 230 V (outside the U.S.) Use a grounded cable, type
SVT or SJT, with a minimum of 18 AWG. The cable must be no longer than 15 feet,
must be rated according to the requirements of the country in which the
equipment is to be used, and must have a grounded plug. The cable should be
labeled "HAR" and should have the appropriate safety approvals for each country.
