Busbars are used to consolidate multiple wires on the a single location or to feed multiple circuits. This busbar would typically be used for AC ground or neutral circuits or for DC negative circuits

Blue Sea Systems busbar with cover for AC or DC use, includes 2 x 1/4" studs and 20 8-32 studs for smaller wires.

The industry standard busbar for positive distribution and the collection of negative or AC ground circuits

New Features

Pressed-on busbar		Because the bus is pressed on to the stainless steel terminal studs, it doesnt require a securing nut that can come loose. In addition, there is a direct compression connection between the copper busbar and wire terminals instead of to a retaining nut.
Insert molded stainless steel studs		In a distribution bus, the terminal stud is a compressive element, not a conductive element. Its purpose is to press the ring terminal against the busbar. Stainless steel studs molded into the base allow for high torque and therefore a tighter connection and lower resistance.
Press-on insulating cover		The insulating cover provides insulation for all wire terminals connected to the busbar. This is especially important when the busbar is on the positive side of the circuit. Also, cover design allows for terminals to be attached to the busbar from any direction.
Raised bus		Raising the busbar above the surface of the base provides unobstructed wiring access, and allows for terminals to be inverted so that multiple terminals can be attached to each stud and screw.
Heat resistant base material		Base material made of reinforced polycarbonate resists high heatit will not burn in the absence of a flame.
