Hubbell 100-Amp Intelligent Y Adapter

Apr 22, 2025
Larger vessels that require 100-amp shore power often dock at marinas that only offer 50-amp service. This is where the Hubbell Marine’s YQ100PLUS Intelligent Y Adapter shines. The innovative device allows the user to safely connect to a single 50A 125/250V AC receptacle, or two same-phased 50A receptacles to run their boat on full 100A power.
Reflecting Hubbell’s commitment to safety, the YQ100PLUS features indicator lights that show if the dockside wiring is correct for adequate voltage — helpful before an owner turns on the electricity within the boat. They also warn if one of the two plugs isn’t engaged properly, which guards against the danger of a live, but disconnected, cord end.
If the marina offers only a single 50A receptacle, using the “A” leg plug of the Hubbell Marine YQ100PLUS brings 50A, 250V AC power aboard. The other cord on this Y adapter remains safely dormant in this situation.
The electronic components stay dry and protected in a lightweight enclosure that is also UV and impact resistant. Sealing grommets keep moisture out. Hubbell’s full-feature connectors and fully molded plugs have cord clamps to prevent terminal strain.
Hubbell’s YQ100PLUS can only be connected to an onboard center-tapped isolation transformer. The adapter should not be used if such a transformer or converter is unavailable.
