Designed to allow user to “string” more temporary power boxes together, using the 50 amp outlet of the box. The male end plugs into the outlet of a temporary power distribution box, and the two female ends feed 50 amp power supply cords to two more boxes. Ends are constructed with an impact and chemical resistant nylon. The male connector is a stainless steal plug shroud with a rigid vinyl protective shell. The female receptacle contains a heavy-duty brass grounding strap to provide a low-resistance ground path and resistance to corrosion.
