NOTES: (1) Heavy duty connectors are defined as having continuous cross section about the periphery of the conductor and through the pad, equal to or greater than 125% of the conductor. (2) Ratings assume use of steel clamping bolts and Belleville spring washers. Higher ampacity ratings can be achieved if conductive bolts, nuts and washers are used. (3) HTJC is the Anderson/FARGO conductive grit joint compound, recommended for maximum conductivity in compression and bolted pad joints. (4) Ratings are based on conductor temperature of 90°C in 40°C ambient, 2 ft/sec. cross wind.
