UL & Canada AGENCY APPLICATION NOTES:

- UL Recognized ("UR" mark) Class ZMVV2 and "Canada" Certified (Canada mark)

- Installation must be carried out only by qualified electricians in accordance with all applicable NEC & UL/Canada standards for the approved application.

- Approved for 90 ° C Temperature Rating Wire, CU9AL

- Amp Rated at 85 Amps for Copper wire and 70 Amps for Aluminum wire

- Wire range, American Wire Gauge AWG 4-14 CU (copper wire), 4-12 Al (aluminum wire) Dual Rated, Solid & Stranded, industrial rigid stranding wire.

- Tightening torques, 4-6 AWG = 45 lb-in, 8 AWG = 40 lb-in, 10-14 AWG = 35 lb-in

- The bar shall be prevented from turning by close fitting walls, or other turn preventive features such as two mounting holes.

- The bar shall not be mounted to a bus bar to act as a power distribution means to or from that bar.

- The bar is designed to be used as a neutral bar for ground or power.

- The bar is for use only in complete equipment where the suitability of the combination is determined & approved by UL

- The mounting screw is to be size #10-32 UNF. The proper use of washers to distribute screw clamping forces on the aluminum should be employed. Bellevilles and lock nuts should be considered in case of vibration.
