NEMA L5-30R

Mid-size boats often use  NEAM L5-30R Receptacles (Twisit-locking type) with a 30 ampere, 120 volt rating electrical system. 

The black is not grounded hot wire and carries 120 volts of electricity, the white is the neutral wire, and the green is the grounding conductor.

It will be also featured with threaded cover and sealing collars providing a watertight connection for use in wet conditions from power source to boat.
