Product Overview

Having trouble finding 50A service? Create 50A service using two 30A connections.

A reverse Y adapter allows you to draw 125V/250V AC current from two 30A outlets. To protect against shock hazard and reverse polarity, a special circuit does not allow current to flow until both plugs are connected properly. This keeps an unplugged plug from being “hot” due to the other plug being energized. The plugs are fully molded and come with sealing collars for use in wet environments.
