Other safety features include an internal relay, which provides open neutral protection, a red LED that indicates power is on, and a 15-amp fuse for current overload protection. The PowerCrew in-box power supply is Underwriters Laboratories approved, and complies with U.S. Occupational Safety and Health Administration-recognized test standards.
