#Surge Protection for Commercial Inclined Platform Lifts
NFPA Article 620.51 (E) Surge Protection NEC 2023
OVERVIEW
Commercial inclined platform lifts are beneficial for making buildings accessible to people with mobility issues, especially in situations where elevators or vertical platform lifts are impractical or cost-prohibitive, by providing a smooth and safe way to navigate stairs.
Today's increased reliance on very sensitive electronics makes surge protection an important topic for inclined platform lifts. The Insurance Institute for Business & Home Safety study found that $26 billion dollars was lost due to non-lightning power surges. In addition, there are about 25 million lightning strikes in the US each year that cause between $650M to $1B in losses according to the Insurance Information Institute, State Farm©.
| NFPA 70, Article 620.51 |
| "620.51 (E) Surge Protection. "Where any of the disconnecting means in 620.51 has been designated as supplying an emergency system load, a legally required system load, or a critical operation power system load, a listed SPD shall be installed." |

This page discusses how to best protect your Inclined Platform Lift system and all the associated components like Electrical Panelboard, lift Controls, Motors, Variable Frequency Drive (VFD), Safety Interlocks, Charge Controllers, and other sensitive electronics.
The SPD Solution
Surge protection is a cost-effective solution to prevent downtime, improve system and data reliability and elimination of equipment damage due to transients and surges for both power and signal lines. It is suitable for any facility or load (1000 volts and below).
Selecting the appropriate SPD for your Commercial Inclined Platform Lifts
NEC/NFPA 70 require that Surge Protective Devices (SPDs) be UL Listed. This means selecting a surge protector is easier than it has ever been. There are only a few choices available for SPD’s that are UL Listed for any of the most commonly used surge standards including UL1449 4th Edition, UL497B, and UL497E.
