Grounding and Lightning Protection Component Certification

Help safeguard buildings and electrical systems with lightning protection system components and grounding solutions that are evaluated to recognized lightning protection standards. UL Solutions assesses lightning protection components and grounding/bonding equipment so you can demonstrate compliance, streamline code authority acceptance and support safer installations across your earthing and lightning protection system.  

Demonstrate compliance to key standards 

We evaluate lightning protection components to ANSI/CAN/UL 96 and grounding/bonding equipment to UL 467, the Standard for Grounding and Bonding Equipment, with support for Canada and Mexico where applicable. This helps reduce the risk of non‑acceptance by the code authorities.  

Support safer, code‑aligned installations  

Properly evaluated lightning protection system components are designed to create a safer path to ground for lightning currents; correctly evaluated grounding equipment supports personnel safety, equipment protection and signal integrity.  

Global market access 

Listings that meet U.S./Canada requirements (where applicable) enable a UL/C‑UL Listing Mark, helping you go to market with confidence.  

Lightning protection components 

UL Solutions evaluates air terminals (rods), conductors, fittings, terminal bases, connectors and similar parts to ANSI/CAN/UL 96. Certifications are available for Class I, II and III components, aligned to installation needs within a lightning protection system.  

Grounding and bonding equipment 

We evaluate a wide range of grounding and bonding products — including ground rods, clamps, bushings, locknuts, hubs, clips, mesh, plate electrodes, couplings, armored grounding wire, water‑meter shunts and exothermic welding systems — to UL 467 in the U.S., CSA C22.2 No. 41 in Canada and NMX‑J‑590‑ANCE in Mexico.  

• ANSI/CAN/UL 96 — Standard for Safety for Lightning Protection Components (harmonized for U.S. and Canada). Listings result in a UL/C‑UL Listing Mark.  
• UL 467, the Standard for Grounding and Bonding Equipment (with applicable Canadian/Mexican standards for regional market access).  

 Lightning protection systems include various components, including air terminals (rods), conductors and fittings, all of which must be UL Listed (ANSI/CAN/UL 96, the Standard for Safety for Lightning Protection Components) according to the installation standards. Lightning protection systems are designed to provide a safer path to ground for lightning currents. Lightning protection systems are customized for individual structures and should only be installed by qualified installers according to the NFPA 780 and/or UL 96A, the Standards for the Installation Requirements of Lightning Protection Systems. 

• The U.S. experiences ~25 million lightning strikes per year, with an estimated $1 billion in structural damages annually — reinforcing the need for properly designed lightning protection solutions.  
• Power quality problems related to grounding and neutral sizing are estimated to cost $15–$30 billion annually, underscoring the value of robust grounding and lightning protection systems.
