What does SJTW mean on a cord?

SJTW is an industry abbreviation used on wire and cable. S is for service; J for junior (which means hard service instead of extra hard); T is the coating (thermoplastic/vinyl); W is weather approved. It is a hard service, thermoplastic cable rated for 300V and approved for outdoor use.

What is the diameter of an extension cord?

The diameter of the conductors within an extension cord are measured in terms of American Wire Gauge (AWG), usually shortened to just “gauge” and expressed by a number. Common household extension cords are available in 16 gauge (smallest), 14 gauge, 12 gauge, and 10 gauge (biggest).

What is the diameter of a 14 3 cord?


Jacket Type SJOOW (Oil/Water Resistant)

Gauge 14 AWG
Length 1′ – 1000′ Foot Spool
Conductors 3 wire

What is the difference between SJTW and Sjtow?

While both power cords are flexible, the SJOOW cord tends to be more flexible because of its EPDM insulation and Neoprene jacket. The thermoplastic material in the SJTOW portable cord, however, makes it more durable.

Is SJOW cord outdoor rated?

Constructed of color coded synthetic oil, ozone and water resistant rubber (EPDM) insulation and an oil resistant thermoset chlorinated polyethylene (CPE) jacket, SJOOW is rated for indoor/outdoor use.

What is the difference between 12 gauge and 14 gauge extension cords?

For 100 feet, the 14 gauge cord works for 11-13 Amps, while the 12 gauge cord is best suited for 14-15 amps. If your cord is 150 feet long, the 14 gauge is best suited for 1-7 Amps, whereas the 12 gauge will support 8-10 Amps. This shows that the extension cord’s length also plays a part in the power it helps safely.

How do I know the gauge of my extension cord?

Gauge is typically listed along with the number of conducting wires in the cord. For example, a 14/3 cord contains 14-gauge wire and has three conductions inside. Extension cord lengths determine the cord’s power capacity. Every extra foot of cord increases the electrical resistance.
