Whirlwind AC-520 20 A Edison Extension Cable

The AC-520 is the extension cord Whirlwind builds for its own power distro work: a Hubbell HBL5366C plug on one end, an HBL5369C connector on the other, and 12/3 SJOOW cable in between. SJOOW is the oil-resistant, weather-resistant jacket rating you want on a floor where somebody will roll a case over it.

Pick the length below. The part number is simply AC-520 plus the length in feet, so AC-520-050 is a 50 ft cord, and Whirlwind makes other lengths to order.
