Knaack for safety The Knaack PowerCrew 15-amp in- box power supply has four GCFI-protect- ed electrical outlets providing 15 amps of power for operating tools or charging batteries. The power source comes via a standard three-prong/straight blade extension cord, which plugs into the outside of the box. This product includes a number of important safety features. One of them, an internal relay, senses an open neutral conductor (broken wire) in the power supply line. If this occurs, the relay remains open, preventing electric- ity from reaching a person.
