wiring a 30 Amp Power Outlet 30A Circuit Breaker {{UPDATE}}

Have a 30 amp outlet next to our TT in the lot but the breaker is in the garage a distance away. so I want to install a 30amp plug with a breaker in the box also so I can shut the power off right at the box when plugging and unplugging the TT into it to save me walking a 100 ft to the breaker box...
I will be buying this box from amazon...
30 amp box and breaker

My question is does anyone have a site to show me how to wire the breaker to the outlet in the box??? checked utube but nothing that I found that shows this, only how to just wire the 30 amp outlet only....thanks

    According to pictures posted by people's reviews there is no pigtail. The box has knockouts for running wires into it. Since you will now have two 30 amp breakers in the line, either one could open if you have an overload. This is not a problem, since you are most likely using the new breaker as a shutoff. The box will work fine.


    Yeah, no pigtail but lugs which do basically the same thing...and actually is better.

  • There are pictures of the wiring in the Amazon reviews. Your existing pvc/wire will enter the bottom of the box. Black goes to the breaker then it goes to the plug. White goes to the neutral lug and then to the plug. Green goes to the ground lug of the box then to the plug.

    Right now your black wire is going to the plug. Your wire is going to the plug and your green ground is going to the plug and to the box itself. The only thing different in the new box is that the black wire will be going to the breaker then on to the plug.

    Don’t count on all of the reviews as being accurate and some are dangerous. One guy suggested saving money on wire by not running a ground to the box and driving a ground rod for grounding. This is very dangerous advice.

    Again, right now your wiring should be black from your existing breaker to your plug. White from your panels neutral lugs and ground from the ground lug bar. Your service panel where everything starts should be bonded which means that the neutral and ground are connected together. If you were to run any 240 volt “sub” panels off your main service they would NOT be bonded so they would run four wires. You are simply running a 120 volt circuit out to your rv, its not a sub panel. Its no different than any other wall plug in your house other than it’s heavier gauge and you are now going to be able to interrupt the black wire.

    I'm guessing, it's all wired up with the breaker already wired to the plug. There is probably a pig tail from the other side of the breaker that you have to connect up.


    THAT would be great if it has that... Its amazon so nobody go really call... thanks
