Blue Sea Systems 2722 DualBus Plus Common BusBar, 150A, 5 x #10-32 Screw / 2 x 1/4-20 Stud Terminals

The Blue Sea Systems 2722 is a DualBus Plus common busbar rated for 150 amps, built to combine negative or AC ground circuit collection and positive distribution on a single block. Each bus provides 5 terminal positions for #10-32 screw terminals plus 2 positions for 1/4"-20 stud terminals, giving installers a mix of screw and stud connection points for wiring runs of different gauges and lug styles.

The studs are insert-molded stainless steel, which eliminates the need for separate securing nuts and allows high torquing for a solid, low-resistance electrical connection. A one-piece serrated flange nut is used on the stud terminals to ensure the connection stays correct and secure under vibration. A clear polycarbonate cover snaps on over the terminals, helping the installation meet Coast Guard and ABYC insulation requirements while still allowing visual inspection of the connections.

This busbar is intended for positive distribution or for collecting negative and AC ground circuits at a single point, making panel and engine-compartment wiring cleaner and easier to service.
