Reference Data Connector Installation Recommendations (continued)

General Information on Bronze or Copper Connectors Bolted connectors and components that are in contact with cable and tube are supplied with “as cast” surfaces. Conductor grooves for cables are designed with ample radii to prevent conductor damage. Connector Design – In all of our bronze and aluminum power connectors, the temperature rise of the connector shall not exceed the temperature rise of the conductor with which it is intended to be used. The temperature rise of an electric power connector which connects conductors of varying sizes shall not exceed the temperature rise of the conductor having the highest temperature rise. All temperatures are based on the conductor being rated at 30° rise over a 40° ambient, indoors, in still but unconfined air. Our bronze and aluminum connectors conform to one of the following as applicable:

Contact Sealants – Various sealant formulations have been developed to provide improved electrical and mechanical performance as well as environmental protection to the contact area. Non-petroleum base sealants are provided for underground applications and other applications where natural or synthetic rubber goods might be adversely affected. The use of sealants is recommended for aluminum to aluminum or aluminum to copper connections which are subjected to severe corrosive environments and when used in direct burial applications such as ground grids. Non-gritted sealants are recommended for flat connections and as a groove sealant in bolted connectors. Our gritted sealants are primarily used in compression connectors. Aluminum compression connectors have sealant applied at the factory. Aluminum stud connectors are supplied with factory applied sealant in the threaded portion. To obtain factory applied sealant in other connectors add the desired sealant suffix designation to the basic catalog number. Example: ACF-6-C-XB “-XB” for petroleum based sealant.
