Basics of...Cord & Cable

AWG - American Wire Gauge: Is a system used for the designation of wire diameter; thehigher the number, the thinner the wire. AWG also stands for the number of electricalconductors in a multi-conductor cable or cord. For example, 14/2 represents a cord withtwo 14-gauge conductors.

OSHA - Occupational Safety and Health Act. Specifically the Williams-Steiger Law passed in 1970 covering all factors relating to safety in places of employment.

PVC - Polyvinyl Chloride. Compound used in thermoplastic (SJTW-A, STW-A) cords.

SPT-1 - Thermoplastic constructed, parallel jacketed. 300 Volt, 2 or 3 conductor, 18 gauge.

SPT-2 - Same as SPT-1 but heavier construction. 18-16 gauge.

SPT-3 - Same as SPT-2 but heavier construction. 18-10 gauge.

SRDT - Range and dryer cord, 3 conductor parallel or 4 conductors insulated thermoplastic construction.

Cord Types

  • TPrene = Thermoplastic elastomer compound used in Polar/Solar cords (SEOW-A, SJEOW-A)
  • S = Standard; rated atVAC.
