This model comes with three different receptacle types, a TT-30R, an L530-R, and best of all two 5-20R plugins. The 5-20R takes a standard 2 or 3 prong plug so no extension cord with a specialized plug in is required.
best investment i have made in a long time. power outages do not worry me anymore because this generator powers everything i need to stay comfortable during a outage. very easy too start and hookup
