Project overview

A critical 4000 A switchboard (MSB4) was experiencing recurring ground-fault events with no clearly identified cause — an unacceptable risk for a venue with no tolerance for unplanned outages during events.
Working with Florida Power & Light, Schneider Electric, and the arena’s facilities team, Progresíve performed time-current coordination analysis and evaluated both incoming and outgoing feeds. Real-world equipment lead times were factored into the repair-versus-replacement analysis. The manufacturer-supported repair we identified resolved the issue — saving capital cost and the continuous rental and fueling of a temporary generator.
Highlights
- 4000 A switchboard ground-fault diagnosis
- Coordination with FPL and Schneider Electric
- Targeted repair instead of costly replacement
