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.
