18-Inch Copper Grounding Braid

This 18-inch copper braid provides a flexible grounding path for commercial electrical installations. It carries 190 amperes indoors and 225 amperes outdoors. The braid is UL467 listed and CSA certified for safety compliance. Tinned copper construction resists corrosion in demanding environments.

Ferrule Ends and NEMA Tongue

Both ends terminate in copper ferrules with a 0.56-inch hole diameter for secure bolt-on connections. The NEMA-style tongues measure 15/16 inch wide by 0.13 inch thick with a 3-inch length. Hole centres sit 1.75 inches apart and 0.62 inches from the end. Two holes per tongue allow standard mounting patterns.

One-Inch Wide Braid for Durability

The braid itself is one inch wide, offering substantial cross-section for current carrying capacity. Tinned copper strands flex without work-hardening during vibration or thermal cycling. Ferrules are permanently attached so no field crimping is required. Suitable for panel grounding, transformer bonds and equipment earthing.

Questions about this item

How do I install the 18 in grounding braid and what step do people often miss?

Bolt the 0.56 in ferrule holes to the mounting surface using the 1.75 in centre-to-centre spacing, then torque to the lug specification; the step most often missed is cleaning the contact faces before tightening.

What maintenance or replacement will the copper braid need over time?

Inspect the tinned copper braid and ferrules annually for corrosion, loose hardware or cracked strands; replace the assembly if the 0.13 in tongue shows pitting or the braid has broken wires.

What limit appears first when the braid runs continuously at its rated current?

The 190 A indoor or 225 A outdoor ampacity limit is reached first; sustained loads above those values will cause temperature rise beyond the UL467 and CSA ratings.
