Pro Installer 400A Dual Bank Control Switch - MC10Another addition to our multi award winning Pro Installer EZ Mount range, the innovative Dual Bank Control switch is like 3 switches in one, House, Start, and Emergency Parallel. Offering easy intuitive control for the boater, the Dual Bank Control switch features a unique isolated-On position which allows use of house loads and VHF radio if the engine needs to be electrically isolated, or allows the engine to be isolated during servicing while still providing power to house loads (for lighting, stereo, fridge etc). For boats or vehicles with single Engine and House battery bank, Dual Bank Control allows the use of optimized battery banks for their respective loads; an appropriately sized deep cycle bank for House loads, and thin plate starting batteries for the Engine. Further, sensitive electronics are isolated from starter motor induced voltage spikes because House and Engine loads are separated during normal operation, unlike Selector battery switches. As easy as 1, 2, 3, these revolutionary EZ Mount battery switches allow you to wire from the front for the easiest surface mounting. With their shared interconnection height, EZ-Mount battery switches "cluster" directly with the Pro Installer Busbar Range, resulting in the fastest, most compact installations. Optimized cable access makes installation a breeze.

BEP Marine Pro Installer 400A Dual Bank Control Battery Switch 772-DBC provides intuitive control over house, engine, and emergency parallel battery functions in a single marine-grade switch. Designed for boats and vehicles with separate engine and house battery banks, it supports optimized battery selection for each application, including deep-cycle batteries for onboard loads and dedicated starting batteries for engine cranking. The switch is suitable for 12- to 48-volt DC systems when both battery banks use the same voltage.
The unique isolated-On position allows house loads and a VHF radio to remain powered while the engine circuit is electrically isolated. This feature is useful during engine servicing and helps protect sensitive electronics from voltage spikes generated by starter motors. Selectable operation includes House, Start, Parallel, and Off positions, giving operators straightforward control in normal, emergency, and maintenance situations. The removable knob also provides an added means of isolating the switch during service work.
Part of the BEP Marine Pro Installer EZ Mount range, the 772-DBC is designed for fast surface installation with front-access wiring and optimized cable entry. Its shared interconnection height allows it to cluster neatly with compatible Pro Installer busbars for compact, organized installations. The switch features ignition protection tested to UL1107 standards, CE compliance, an IP67 waterproof rating, fiber-reinforced construction, tinned copper studs, and stainless steel hardware. Three removable side plates help protect connections, while each switch is individually tested for pressure sealing, rotation force, and electrical load performance. Rated for 400 amps continuous, 600 amps intermittent for five minutes, and 1,500 amps for ten seconds of cranking when properly cabled.
