NEW Survey Results - Appendix, Verbatim Responses Download
In 2017, the Electrical Safety Foundation International (ESFI) conducted a survey of electrical designers, planners, and engineers and found that there was a limited understanding of the purpose and effectiveness of surge protection devices. In response to the survey results, ESFI created educational materials to spread awareness of surge protection.
An important factor revealed by this survey was the failure of industry engineers and experts to distinguish surge protection devices from over current devices or circuit interrupters (such as a GFCI breaker). SPDs are designed to handle fast transients or surges, rather than excess voltage or current. While some Type 1 SPDs may be equipped with external overcurrent protection, it should be noted that this is not the case with all variations of SPDs, and that it is not the preliminary function of the devices. Likewise, overcurrent devices do not provide surge protection.
In a 2017 survey of electrical designers, electrical planners, and electrical engineers who worked in designing / renovating electrical systems in industrial facilities, healthcare facilities, and IT centers, the Electrical Safety Foundation International found that:
94% of those surveyed found surge protection to be very or extremely important to building owners and tenants.
