What not to run....

[stepbill]

If I have an extension cord running from my TT to the house on a 15amp breaker, what should I not turn on while connected to this? I'm assuming the micorwave and A/C but is there anything else that I should not turn on? Is turning on the water pump or the fridge for pre-cooling prior to a trip OK? Thanks for your help as I am new to this.

Can the fridge run off the battery while it is connected to the tow vehicle and traveling?

Fridge draws about 3-4 amps when plugged in. So you should be fine with that. Water pump is 12 volt so it runs off battery power, which is replaced by the converter when plugged in.

Most fridges don't run on 12v DC aka battery power anymore. If you want/need to run the fridge while on the road you will need to use the LP and leave the batteries on to keep the control circuit active.

you probably have an amp or two immediately whenever you are on shore power. The batteries are being charged, some of the lights are on, etc. Definitely not the hot water heater. You should be ok running the small electrics but definitely none of the majors. Usually a standard house type15 amp breaker will trip around 60 - 80% of it rated current load.

When I camped at my grandfathers cottage we were able to run everything with out a problem. What always tripped the breaker was when we ran the microwave and AC together. Just shut the AC off and you’re good.

Are you sure they're 15amp? My house has 20 amp breakers and it runs my air with no problems. I only use it the day before a trip (nothing else), it helps the fridge cool down faster, which I just run on propane until we get to the campground.

I can run mine the same way but make sure you use a heavy extension cord ....if I use a small cord it will blow the breaker

Yes. I have a spare 30amp power cord that I cut the end off and put a house plug on.

2 reasons, those eventually burn out, and I fried the end off of my original power cord at a campsite, hence the spare cord.

Those adapters may be fine for occasional use, but my camper stays plugged in 24/7, I would not recommend one for that.

I prefer the corded adapters myself, they seem to be better constructed than this little guy. I agree that these small adapters should be used only in case you are in a bind and I guess if you have a clear and present need for a well built full time one instead of one that you would use because they gave you a 30 amp site instead of a 50 amp site, they are a lifesaver to have on hand. I have one of each to adapt my 50 to whatever I end up with and they are ALL corded (about a foot long) and more expensive (but better built). Besides, I would not recommend the use of a plain extension cord to power my RV.
