In-box power supply
The PowerCrew 15 A in-box power supply provides safe in-box power in any brand or style of jobsite box. It has four GCFI-protected electrical outlets that provide power for operating tools or charging batteries. If an internal relay senses an open neutral conductor (a broken wire) in the power supply line, it remains open preventing electricity from reaching a person who might make contact with the broken wire. A red LED indicates the four outlets have power.
