NFPA 99 articles 6.3.2, 6.3.3, and 6.3.4 detail various testing requirements for all newly installed Isolated Power Systems to be thoroughly tested prior to first use. On-site Start-up Hospital Isolated Power Panel Commissioning and Line Isolation Monitor (LIM) testing by a PG LifeLink factory trained Field Service Technician is offered with equipment for all new installations.


Start-up Hospital Isolated Power Panel Commissioning assures facility owners and design engineers that all construction materials and workmanship comply with code requirements for new installations. Successful commissioning validates the factory warranty on the Isolated Power System.

Per article, testing must also be performed using external simulated faults after any “repair or renovation” to the system. PG LifeLink Technicians can provide recertification testing for any brand of Isolated Power equipment. Recertification completed by PG Lifelink of renovated systems documents compliance with NFPA code requirements.

Start-up Commissioning Test and/or Isolated Power Panel Recertification Includes:

  • Inspection of contractor-installed wiring and devices
  • Verification of NEC Article 517.160 installation specifications
  • Verification of NFPA 99 required criteria, including:
    • Fault, monitor and Total Hazard Current (THC) readings
    • Line-to-ground impedance verification using the measurement methods specified in NFPA 99 article
    • Line Isolation Monitor (LIM) testing
    • Remote monitor operation check
    • Receptacle ground impedance measurement
    • Conductive surface touch voltage measurement
  • Training is provided for facility personnel on equipment operation, maintenance, annual testing, and documentation requirements 
  • Test Report is provided upon completion and Log Book is available for future facility-maintained record keeping

PG LifeLink standard lead time for service scheduling is 20 business days advance notice for Factory Start-up Commissioning or Recertification testing to ensure technician availability.
