Electrical Power Harness is designed for use with the HON Initiate or Simplicity II Panel Systems to distribute power in either direction. Harness helps facilitate electrical connections into panel configurations so you can simply plug electrical devices directly into panel bases instead of cluttering your floor space with multi-outlet surge protectors. Power harness is double-sided so receptacles (sold separately) can be inserted into both sides of the harness power blocks. Three-way panel connections require at least one power harness. Four-way panel connections require at least two power harnesses. A licensed electrician should install this component into your panel systems. Four-circuit components and three-circuit components cannot be used together. Harness meets or exceeds ANSI/BIFMA performance standards.
