Dale,
Yeah, that's what it is. I wanted an accessible switch for a battery main shutoff. Even though all my wiring is fused, including a circuit breaker on the battery line to the main fuse panel, I wanted a way to quickly isolate the battery. Battery shorts are an ugly business. I need to learn to use it when I'm working on the wiring. I've blown four fuses dinking with the stereo and lights. No big deal if everything is fused, just replace the fuse and be more carefull.
You may or may not need a main circuit breaker with the panel if it has two 15A circuit breakers. You'll only be able to power 15A worth of load split between the two circuit breakers if you use a 15A plug. I'd go with a 30A plug if you want use all the capacity. Make sure that #10 wire is used to feed the line side of both the 15A circuit breakers. But, if there's a short upstream of your panel you'll be relying on the campground circuit breaker to protect your wiring. I used a circuit breaker at the point where my wiring entered the trailer so all my stuff is protected by my circuit breaker. I didn't want to rely on the campground circuit breaker to keep a years worth of work from burning down. Also, NEC requires a circuit breaker there anyways. There's that ugly "C" word but I think there's a good reason for the circuit breaker. I've seen some nasty wiring at campgrounds.
