Question: Looking for a mechanical fitting to connect cable from ground rod to the building steel beams. We cannot drill the beam and exothermal cannot be used.Anyone have a good mechanical fitting they have used that works and is listed for the purpose? I'm thinking of one that clamps to the edge of the beam. I looked in Burndy but didn't see anything. I recall back when seeing clamps on a job but don't recall who made them.Thanks,RC
Clamps for Cable to Steel Beam Connection
ABB/Thomas & Betts PowerClamp
Clamps onto the edge of the beam without drilling or welding. Listed for grounding applications.
Panduit PCM Series
Beam clamps with adjustable saddle to accommodate different beam sizes. UL and CSA listed.
NEMA Standard 83C
Contains specifications for cast iron beam clamps for grounding applications.
WESCO Webi Clamp
Clamps onto the side or edge of beams and is designed for grounding.
ERI Clamp
Edge-mounted clamp with a split bolt connector. UL listed.
Considerations
Ensure the clamp is sized appropriately for the cable and beam. Use a large washer to distribute the load on the beam. Tighten the clamp bolts to the specified torque. Follow all manufacturer's instructions and local codes.
Tips: If possible, place the clamp in a location where it will not interfere with other equipment or maintenance activities. Consider using multiple clamps for increased holding strength. Inspect the clamp periodically and retighten the bolts as needed. Flag for review
