About this product

The Blue Sea Systems Common 150A BusBar is a common busbar family for consolidating positive distribution, negative returns, or AC ground circuits on boats using up to 48V DC or 300V AC. The range carries a continuous rating of 150A DC and 130A AC, with layouts that use four 1/4"-20 studs or a mix of #8-32 screw terminals and two 1/4"-20 studs.

This busbar is a practical fit for electrical panels, battery switch areas, charger and inverter installations, and other places where several circuits need a shared connection point. The tin-plated copper bus helps maintain conductivity in marine electrical work, while the UL 94-V0 rated glass-reinforced thermoplastic base gives the terminals a stable mounting platform.
