The special Pro Glo® SJTW (300V) jackets offer high visibility for safety underfoot and extra flexibility in cold weather. The triple tap connector provides three standard 15A-125V outlets for additional power where it’s needed. Each male plug has a built-in amber neon light which indicates that there is power in the cord and outlet. In addition, these extension cords provide continuous current and ground monitoring (CGM), an OSHA safety requirement. A green neon light in the triple tap female connector lets you know at-a-glance that there is ground continuity.
