Surge Protection for UL96A Master Label Lightning Protection System NFPA780

Surge Protection for
Lightning Protection System (LPS)

Empire State Building - Lightning Protection System (LPS)

NFPA780
Reference Standards : NFPA780, UL96A, UL1449, UL497A, UL497B, UL497E

Today's increased reliance on very sensitive electronics makes surge protection an important topic for Lightning Protection Systems or LPS. 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©.

This page discusses how to best protect your a building or residence requiring a Lightning Protection System (LPS) following The Standard for the Installation of a Lightning Protection Systems, NFPA 780.

Selecting the appropriate SPD

Surge Protective Devices (SPDs) shall be UL1449 Type 4CA or better including Type 1, Type 2, Type 1CA and Type 2CA. Per ANSI C136.2-2017, it should be tested to the appropriate exposure level based on the application or installed location.

The UL1449 Type 4CA Surge Protective Devices (SPD) have undergone more stringent safety testing than UL1449 Type 5 Components including the critical abnormal overvoltage - limited current testing.
