Running A/C & microwave
Hi
I have a 2011 Roo 23SS. While camping over the weekend the wife went to use the microwave while the air was running and it popped a breaker inside the camper. We were plugged into 30 amp service from the CG, and it was a State Park so I assume (I know that's bad) that they have good power. I am just wondering if this is a normal thing or something I should have checked out.
I am not that " electrically inclined" so I just assumed that I we had 30 amp service then I should be fine running everything in the camper. If it helps to know, yes the fridge and hot water were running on electric also.
While on this subject, does anyone know if it's possible to turn off the WFCO converter? I am just wondering about this for times when I use a generator. I have a 3000 watt inverter generator, it is sufficient to run the A/C but I have had it overload before even with all the breakers off except the one for A/C. I am thinking maybe the WFCO is trying to charge the battery causing an overload?
Thanks for any help!

i believe the hw heater may be too much. in my last trailer, i could run frig, microwave, and air on the 30 amp. did not have the electric hw heater.
should u run on gen, i would put the hw heater and possibly the frig on gas. i would think the gas would be cheaper operation than the gasoline.
i have found the frig and hw heater aren't big users.
when i hooped up to 20 amp service, it was an either or with the air and microwave. frig was on electric and hw heater on gas.
in a word, i don't think u have any problems, just a little too much demand.
oh, and my converter was never shut down.

We have the 2012 318BHS and got it set up for its maiden season at the deer lease this weekend. We tripped the outside breaker at the pole by running electric hw heater, a/c, and micro along with lights and stereo. Oh yeah, the pump was working too since I was running some bath water. We are lucky we didn't blow a fuse inside! We just weren't thinking....

As far as the gennie goes A 3000 watt gennie will not run much.
Considering all your plug ins are most likley 20 amp.
Even so your a/c will drawn about 16 or so amps at start up and 13 or so running.
That only leaves you about 5 to 6 amp to Max it out.
As far as chi power start adding all you had on and you may have been close to 30 amps.
I would not recommend turnning off converter. I have an amp chart ill post later.

If you turn everything on at once you can easily overload a 30 amp trailer.
Especially if the hot water heater and refrigerator happened to be cycling at the
same time as the AC and microwave. I would expect something to give!
My trailer has a circuit breaker for the converter. Doesn't yours?
I once had my trailer hooked to a generator and noticed the genny was working extra
hard. I was just trying to charge batteries. I realized later that my refrigerator was
in "auto" mode and as soon as I fired up the genny the fridge had switched from
gas to electric.
If you're close to max on your generator to run your roof AC on be sure and shut off
the 120v hot water heater AND switch the fridge to LP mode.

I run the Fridge, AC, Microwave, couple of lights and TV all at the same time plugged into 30 Amp shore line. Being that it is stil new...run it to the dealer for a check up.

One other thing to keep in mind is many RV appliances require more amps to start the appliance than they do to run the appliance. A roof air conditioner can draw 16 amps to start, but may only use 13 amps once it is running.

in my quick calulations
ac = 12
convertor = lets say 4 half of full
hw heater = lets say 11
micro = 13
if they were all running at once .... 40 amps

When I have problems just like this. If I run the water heater on LP it seems to be okay. With all the gadgets in the newer campers, we are pushing the limit at 30 amp. It doesn't take much to pop a breaker! Just as a note: I use the extra 15 amp 110 outlet at most CG to run my awning lights and any other outdoor item such as a electric griddle etc. Just run a extension cord under the trailer and make it available using a 8 plug strip with a circuit breaker built in.

Thanks everyone. Since I don't have that much electrical experience it just made sense in my head that the manufacturers would take loads into consideration when building these campers! It seems to me that it makes more sense to build them all at 50 amp rather than 30 but I'm sure the cheap factor is what determines how they actually build rather than usefulness.
Thanks for all the good info.

50 amp converters would be great but, not every campground (especially older ones) have upgraded to 50 amp in their pedestals yet (if they even plan to). So, we're still stuck with 30 amp "old" breakers that have been "used and abused, turned off & on" for years! I have run into this several times and like you, popped a breaker, only difference was, it was their breaker in the pedestal.

I am not sure what you mean about 50 amp converters would be great but not all cg's have 50 amp service ?

A larger 50 amp power center in the TT. And I've been in cg's where there is only 30 amp service at the pedistal.

Your converter size has nothing to do with incoming amp from cg power.
your converter size/amps is output amps not input.

I realize that. All I was trying to do regarding post #10, is say that even if you had 50 amp in the TT but, only 30 amp at the cg's pedistal, you're at the mercy of the cg's 30 amp breaker!
