Shore Power Inlet Adapter

[8ball_99]

Plugging a 15amp cord into a 30 amp plug isn't a great idea, But its pretty common in the RV world. There is nothing protecting the cord or the connection to the power strip in the bus.. Sure the power strip has a cheap breaker inside it. Just the cord right up to the breaker can melt.. I"m sure someone somewhere makes a 30amp to 15amp pigtail with a 15 amp breaker might just cost a little more..

If you have a direct short in your 15 amp, #14 gauge wire entrance cable, that will cause the 30 amp supply circuit breaker to trip.

If your RV has a 15 amp circuit breaker, it does not matter that it is on the opposite end of the service entrance cable with it's 30 amp breaker, it will trip if > 15 amps happen.
If the 15 amp breaker is broken, then the 30 amp breaker will trip, when > 30 amps happens.

The point is that electricy has to have a complete path.
It does not matter where in that path you place the circuit breaker.
It can be in the campground supply panel, right after the entrance to the RV, or even after the load.
It only matters that the path is broken, if circuit breaker is tripped.

I guess we can agree to disagree. A short in the cord or in the plug or even in the power strip before the 15 amp breaker can and would Easily melt that cord before the 30 breaker tripped. I've seen it first hand... Try pulling 20-25 amps through a 14gauge extension cord.. Which is exactly what would happen with a short..

I think I'm going to have to disagree as well. A circuit breaker opens due to the heat generated by excessive current passing THROUGH it. If a short happens UPSTREAM of a breaker, the excessive current will not pass THROUGH the breaker, and no heat will be generated to trip it.

What you're saying is like wiring your entire house straight from the 200 amp main breaker, and then putting a power strip in every room to plug in appliances.

One more option thrown out there, put in a 30a inlet. From the hot side of the inlet, run 10g wire to a 15a pannle mount fuse, which requires a lot less room to install than a breaker. from fuse, wire interior and exterior outlets using 12g wire, running thier neutrals and grounds back to the inlet. With this set up an adapter can be used to plug the 30a plug into a 15a receptical with no worries.

I am so confused.

I use a 30-to-15 amp pigtail, but I never considered the extension cord. It's heavy duty, I think. It's the thickest one I have, but I don't know it's capacity. Next time I'm at the trailer, I'll have to check it out.

Or, since I'm usually early to the campsite, I can grab a 15amp outlet and let the others be damned.

Its not the end of the world your bus is going to burn down to the ground tomorrow kind of deal. Like I said in the RV world its pretty common practice. If you have a good heavy insulated 12 gauge extension cord technically it can handle 30 amps.. They are only rated for 20 though. And any smaller wire would be at risk. Chances are your power strip only has 14 or 16 gauge wire in it and connections and switch are rated at 15 amps. Since thats the part that is Inside thats probably the biggest concern. If there was a short the wire in the power strip would light up like a light bulb and melt/burn it in seconds long before the breaker tripped. If you install a fixed input like your talking about and you keep the possible amperage in mind you should be fine using the cord and adapter.

Or you could always just run a 30 amp 10 gauge cord to a small breaker panel in the bus then from a 20 amp breaker run your 20 amp drop cord to the trailer and your good all around..
