House AC went out can I hook up to 20 amp gfci

[Johnsonty131]

Long story short ac part for house won’t be here till Saturday. 2021 keystone hideout 176bh says ac BTU is only 13,000. Can I safely run this from my normal house outlet? (I have the dog ear adapter for the 15 amp to 30)

Usually on a 20 amp (T-shaped neutral) circuit you can run 1 "Big ticket" item (A/C, Water heater, Microwave) as others have said run the fridge on Propane
And make sure the batteries are full (Give them at least 2 or 3 hours of "plugged in" time before you run the A/C)

Of course this only works if your spouse is not Eva Gabor (Reference to TV show: Green Acres)

Are you using an extension cord? That will reduce the voltage if so. If you have a way to monitor the voltage in the trailer then keep an eye on it. It will probably be OK.

I see you already did, and it worked out. Now you know it’s time to run a dedicated 30A service for the RV.

Thanks guys I slept in camper last night and dog ear never got hot, just a little warm and voltage was always over 120!

Hi,

I'm comfortable running the roof air so long as voltage is no lower than 108. I monitor it with a Kill-a-Watt meter.

If it is lower than 108, I add the autoformer to the circuit.

Yes, plug in and let it rip. Once running check the voltage is above 110 in the RV.

If the breaker overloads.... turn the fridge and water to propane only. If it still overloads let the battery charge for 60 minutes and try again.

And forget the microwave or the hairdryer. TV and lights will be OK.

If the GFCI trips.... ok that is more involved.

You don't need to turn off any breakers if your battery is charged.

If your battery is low, let it charge a few minutes before you turn on the AC. The charger may draw 4 amps for a short time

[Johnsonty131]

So my 5 breakers are 1 . Interior zone 1 15 amp
2. Furnace and ac 15 amp.
3. Water pump 10 amp
4. Exterior light 15 amp
5. Awning
6. Battery charge 30 amp. Am I turning off this one

And make sure there aren't any coils in the extension cord.

.... Also how do I know if I’m burning up the circuit? Just use multimeter on the outlet im hooked up to?

Measure the voltage at an outlet inside the camper. Make sure it stays 110VAC or above. A Kill-O-Watt meter comes in handy for this.

Hold the plugs at the GFI outlet and extension cord to see if they are getting hot. A little warm is expected.

just be careful in extension cord length and AWG. Use 12ga and as short as possible. Or best if you can just use the 30A from the trailer to a dogbone at the outlet.

Maybe 15a, but might need 20a.

be nice if it was a 20amp out let, and I,d not use any thing else on that line. I run my rv ac off one with no problem.

He said it was 20A in his title.

I am guessing the statement in the actual post "I have the dog ear adapter for the 15 amp to 30" threw some people off. But yeah, 20A should be no problem.

I would not run anything on the same line, in the house/garage, such as a freezer/washer/dryer in the garage.

[midnightsadie]

all ways some idiot butting in on the 20amp read I,d put my hand on the cord close to the connection see if its warm .Texas a hot place I,m in ohio hot to us is about 80deg.
