	"SJT" is one of many designations used by Underwriters Laboratories
(UL) to decribe the use and insulation catagory of wire and cables.

	Common power cords made of rubber or plastic all begin with a
designation "S".  A cord designated "SJ" is a rubber cord rated at 300
volts maximum at a maximum operating temperature of 60 deg C, with an
intended application of "light duty service".  A cord designated "SJT"
is the same as "SJ", except that the insulation is thermoplastic instead
of rubber.  Most electronic equipment uses cords designated as "SJ" or
"SJT".
