Built for heavy duty industrial use, Appleton Group's McGill brand of extension cords are NEC and CEC Listed. They are available in a variety of lengths and sizes, with oil- and weather-resistant jackets and ratings up to 600 Volts. Nyloc safety grip plugs and connectors are designed for fast, easy wiring and provide safe, durable nonmetallic cord grips. McGill’s selection of ground fault circuit interrupters for portable tools and lamps includes standalone units as well as models with attached power cords and single or multiple receptacles. Safety motor controls are available to prevent accidental restarting of small motors when power is restored following an interruption, and electrical plug lockouts that prevent unauthorized insertion of a plug into a receptacle.
