Run on 30Amp @ Park w/ 50amp service?

Just got a 34TBOK w/ 50 amp but do not have the 2nd A/C and only 10 gal gas/electric water heater - do you have to run on 50 amp at the parks or are you OK to run on 30 amp since no 2nd A/C?

Your ok running a dog bone 50 to 30 amp adapter.
Normally the 50 amp service is for second a/c
You most likely have second a/c prep.

So if campground has 30 amp & 50 amp service - and the 30 amp spots are better - is it really OK to run on 30amp or will there be harm done to anything at all for the whole season?

You would be fine. The amperage rating is just what is available, not what you are using. Without a 2nd AC, you should not use over 30 amps. If you somehow do, the breaker on the campground box would trip, no damage to your unit.

it is really ok .

And normally the extra 50 amp leg only runs the second a/c which you don't have.


good list to have .

We ran our 50 AMP cord off a 30 AMP campground pedestal using a dogbone adapter all last summer without any problem. BTW we've got 2nd AC ready but no AC in the bedroom either.

Hope I'm not hijacking thread. New owner of Rockwood 1905, maiden voyage this spring. With minimal use of heat & one A/C unit, microwave and given use of fridge, lights, stereo on shore power can we get by on 15 amp service or should we be looking at 30 amps?
Thanks, Norm

Thanks, Norm
Heat requires more than 15 amps since the heater alone pulls 15.5 amps.
The air conditioner also runs about 14-15 amps depending on size.

Forget the rest (stereo, TV, etc) if you only have 15 amps available.
Get the 30 amp site if you can.

Thanks herk, that's what I thought. Got a lot to learn about this stuff.

If we are only using lights & stereo, no water systems, heat or cooling (like when we were tenting) 15 amps should be OK, right?

Your lights, stereo, and furnace are 12 volts systems so you should have no trouble using those with a 15 amp plug. The trailer's converter will take the 110 volts and convert it down to 12 volts. You should also be able to use the water heater and your refrigerator on propane without a problem. You should be able to watch television also. You might also be able to run your microwave. Forget using the air conditioner and other power hogs like hair dryers and space heaters.

I forgot to mention that your water pump is a 12 volt system too so if you have to use your fresh water holding tank you'll be good there also. Be sure to know the location of your circuit breaker/fuse panel in the trailer just in case you do trip a breaker you'll be able to reset it. You've got a perfect trailer for camping so have a great time with it.

Well... I have had an issue with a tripped breaker already and not sure why. Plugged the cord into garage power first. When power cord was connected to trailer sparks flew and breaker tripped. ???

The big AC hits are air conditioning (~1900 watts), electric fireplace (heat ~1500 watts), electric coffee pot ~1100 watts), and the microwave (900 watts - 1200 watts depending on model).

The rest you could probably get by with a 10 amp AC service with everything on. Add any one of the others and you are busted.

I hope you did not plug it into a 220 dryer outlet.
If so, I am so sorry; the news for you is not good.

A 30 amp camper is not 220 (even though it "looks" like it should be) but 110 volts.

Also NEVER (need to repeat this - NEVER) plug your camper into an energized circuit. Turn off the breaker at the pedestal before you connect the camper. If you left the Air Conditioner switch on when you plug in you will get a HUGE arc that will destroy your camper socket and power cord.

If there is no circuit breaker at the pedestal to turn off when you connect, turn off the MAIN circuit breaker at the power center inside the camper; then connect.

Of course you should follow the same procedure when you disconnect as well.

A power monitor (like a surge protector) will also prevent you from hooking up bad power to your camper. It will not allow power to flow if it is bad.

Hey herk, thanks for your input. I have no reason to believe that I plugged into anything other than 110. The circuit I plugged into was an energized household circuit. Once the breaker in the trailer was reset there did not seem to be any further problem. I get what you are saying about an energized pedestal, or a trailer that has stuff turned on when disconnected. Not something I thought about before but worth remembering. So it would seem worthwhile to ensure that my trailer main should be off before I hook up to any power source as well as ensuring that any appliance drawing power should be off. Common sense. And yes it would apply as well to disconnects. I have read a little about surge protectors and some say they have trailered for years without one no problem. Ditto water pressure safeguards.

Also, in the scenario of plugging into an energized household 110 circuit, it should be OK if the trailer main was off during the plugin and then turn the trailer main back on?

Older trailers had bullet proof electronics. The newer ones have way more computerized features. The days of pilot lights are gone.
