Common wire gauges include 10 AWG, 14 AWG and 16 AWG. Typical maximum amperage ratings shown across these options are about 30 A, 15 A and 13 A respectively; actual rating depends on the specific cord model.
Green jackets are used both to improve visibility in low light (bright/high-visibility green) and to blend with landscaping (muted green finishes), so manufacturers offer variants for safety or aesthetic concealment.
Some cords include a lighted end with a built-in LED to show when the cord is live. Other convenience features include ground-stake power strips with timers, photocell sensors, and remote-control functions.
Maximum wattage ratings range from about 1,625 W up to 7,500 W, with intermediate ratings such as 1,875 W and 3,750 W. The actual wattage capacity depends on the cord’s gauge and amp rating.
Common connectors include standard grounded 3-prong outlets, RV-specific NEMA TT-30P/TT-30R, and generator-style twist-lock NEMA L14-30P/L14-30R. Conductor counts shown include three-wire (grounded) cords and four-conductor cables for some heavy-duty generator applications.
