Hubbell Marine’s newly redesigned 100 amp intelligent adapter can safely power a 100A 125/250V AC boat from two 40A 125/250V AC receptacles at dockside or from a single 50A 125/250V AC receptacle acting as a single adapter.
Internal logic senses that:
- Both plugs are fully engaged (i.e., one is not dangling loose while the other is plugged in) or the “A” leg plug is engaged to access a single 50A 125/250V receptacle
- The polarity of the receptacle on the dock is correct (i.e., no miswiring of the hot and neutral wires)
- The two receptacles are from correct phases
Housing Design
- Rugged smaller, lighter-weight enclosure
- Environmentally sealed against humidity, fog, and rain
- Sealing grommets keep moisture out
Safety
- Indicator lights indicate correct polarity and safe operation
- “A” leg for accessing a single 50A 125/250V receptacle
