ESFi Survey Report
The Electrical Safety Foundation International conducted a survey in 2021 among professionals in industrial and commercial facilities. This group included managers, owners, building engineers, maintenance heads, and other related roles that shared valuable insights on power surge incidents, their impacts, and the adoption of Surge Protective Devices within the facilities under their management.
Key findings
Surge Protective Devices Work

Unplanned Outages Causes
- 34% of unplanned outages are caused by power surges and unexpected resetting or misoperation of equipment (commonly causes by power surges)
- Unexpected downtime is common with over 72% of facilities surveyed experiencing downtime more than a few times a year
- 23% of facilities installed Surge Protective Devices after experiencing a surge event
- 78% of equipment failures caused by power surges were in service for 5 years or less
