12-inch copper grounding braid

This 12-inch copper braid carries a 190-ampere indoor rating and a 225-ampere outdoor rating. It is built for commercial electrical installations that require a flexible grounding connection. The braid uses tinned copper strands with copper ferrules on both ends. It meets CSA and UL 467 standards for grounding and bonding applications.

Current capacity and thermal performance

The ferrule design handles continuous current up to the rated amperages without overheating under normal conditions. Tinned copper resists oxidation, keeping contact resistance low over time. The 1-inch braid width provides ample cross-section for the stated load. No active cooling is required for this passive conductor.

Ferrule mounting and hole pattern

Each ferrule has two mounting holes with a 0.56-inch diameter. Hole centres are spaced 1.75 inches apart and sit 0.62 inches from the ferrule end. The NEMA-style tongue measures 15/16 inch wide and 0.13 inch thick with a 3-inch length. This pattern suits standard busbar or enclosure grounding studs.

Questions about this item

How do I install the 12 in copper braid with ferrules on both ends and what step do people miss?

Bolt the 0.56 in holes to the mounting surface using the 1.75 in centre-to-centre spacing, then torque to spec; the step most people skip is cleaning the contact faces before tightening.

What maintenance or replacement will this grounding braid need later?

Inspect the tinned copper braid and ferrules periodically for corrosion or loose hardware; replace the assembly if the braid shows broken strands or the 0.13 in tongue thickness has eroded.

What limit appears first when this braid runs at continuous load?

The 190 A indoor or 225 A outdoor ampacity rating is the first limit; sustained current above that value will cause temperature rise beyond the UL467 listing.
