About Extension Cords

Abrasion-Resistant Extension Cords
Thick insulation protects the internal wires of these cords, so they can be used in high-traffic areas and over rough surfaces. The industry designation is STW, so the insulation resists water.
Cords with a NEMA TT-30 plug and socket are commonly used to power RVs. They have a high current rating.
Cords with a 90° elbow plug fit flush against a wall outlet, so they fit behind machinery or in areas where space is tight.
