Rather than a lift gate power connection, I mounted under the wing an
Anderson Power Products POWERMOD HP A Series connector rated at 225A. The "B" series is a 400 A rated connector.
The are latching and come in a bulkhead fitting shown below.
The mating connector (also available as a 90 version)
If you want to go with a through wall, panel mount, power post, VTE Warehouse makes a
Copper Core Power Bushing that handles 550A. They have mounting plates listed under their
Copper Core Jumper Bushing. They also have a variety of insulators.
