How to Properly Size the Primary Main Circuit Breaker
To ensure proper protection of PG LifeLink Isolated Power Systems, it's critical to select the correct Primary Main Circuit Breaker rating based on transformer size and input voltage. The table to the right outlines our standard recommendations, based on UL 1047 and best practices derived from NFPA 70 (NEC Article 517) and NFPA 99.
Consider Inrush Current
Isolated power transformers are inductive loads and can experience inrush currents up to 10x the rated FLA at energization. This surge may last up to a full second. To protect upstream equipment and avoid nuisance tripping:
- Upstream feeder breakers should be sized 10-20 A higher than the main isolated power panel breaker
- Use breakers with adjustable instantaneous trip delay

Importance of Proper Breaker Sizing in Hospital Isolated Power Systems
Correctly sizing the primary and upstream breakers in an Isolated Power System ensures:
- Reliable power continuity in critical care environments
- Full code compliance with NEC Article 517, NFPA 99, and UL 1047
- Protection against transformer inrush surges and nuisance tripping
