INSTALLATION

Wire connectors are intended for use in installations covered by ANSI/NFPA 70, ‘‘National Electrical Code’’ (NEC), and should be installed using the prescribed manufacturer’s installation instructions.

"Stacking of connectors (multiple connectors assembled using a single bolt, nut and washers) may be permitted where mechanical interference is reduced or eliminated with the use of offset tangs, stacking adapters, and the like. The surface contact area of the mounting tang should make complete contact with the mounting surface or the previously stacked connector tang."
