A/C power

[Ljnasa]

I would like to know if I can run one of my A/C units on a regular house outlet. I have a 2017 Grayhawk 31DS with the 2 11,000 btu A/C’s.
I plug my motorhome in the night before we leave to run the refrigerator. I know I can run the generator for the 2 A/C units but wanted to se if I can run the one unit to pack the motorhome.

Thanks

If the outlet is on a 15amp breaker and nothing else is turned on in the house on that breaker, maybe. It will trip immediately as AC needs the most power at start. 20 amp I think would be ok (with nothing else turned on using the breaker), but I havent tried it. When it comes.to.packing or unpacking we just use the Gen. It makes everyone much more happy (both ACs, lights, fridge, etc with no worry about popping a breaker/fuse.

If you have 2 AC's then you have the power management system. In the menu for it, you can select 15 or 20 amp service. I suppose if you pick 15 amp and turn both AC on, it will figure it out for you. That is if your house circuit can really do 15 smps.

I used run my 13.5 on a 20 amp receptacle. I was limited to only the AC so I installed a 50/30/20 RV box with dedicated wiring.

Watch your voltage. If drops to 105 volts, turn off the ac. Otherwise you could damage the ac unit.

You will have no problem running one a/c unit. Just don't microwave your coffee, I have actually ran mine for up to a week on a 15 amp circuit.

Thanks everyone for the input, I have a 20 amp breaker so it should work fine then.
I just wanted to know in case I wanted to run it for a 8 hour period if neede without a generator running.

Thanks , again

We have two 11k a/c units in our Greyhawk and will run one plugged into a 20 amp outlet with a adapter when in our driveway.

Be very careful with the adapter. Some are not the best and can get very hot when running the a/c...so check it often! If you notice excessive heat at the adapter turn off the a/c. Running one of our a/c’s the Power Management is showing 12amps being drawn. Buy the best 30amp to 20amp adapter you can find and don’t overload it.

Be sure the refrigerator is not on or is on propane. Also be sure the hot water heater is off or on propane. Don’t use the microwave!

I plan to have a dedicated 30 amp Rv plugin put out by the driveway just for this purpose. I had one at my previous house and never had a worry and could run everything in the RV no problem. Not that expensive to do.

Ok,thanks
The 30 amp is the safest bet, I think I will do that.

Upgraded service a few years ago and put this in.. Its nice to have.

I have run my 13.5K units for years on a home 20A outlet. It has never tripped the breaker and the A/C never struggles to start.

[bababooey]

It's kind of subjective, most people dont have a 15 or 20 amp circuit that has no other load on it. To say it worked for X or Y is not a definitive answer unless you describe the other devices/loads on that circuit.

Nice! I have a little outbuilding by my driveway that has 50 amp running to it. I plan to put me a dedicated 30 amp plugin out there using that service. I don’t run anything else except lights normally so it shouldn’t be a problem.

A note that significantly helps this issue: I tested running my A/C on my 2018 Seneca with five different extension cables on my 110v standard GFCI outlet. Three different standard cables tripped my home breaker. I went to home depot and purchased a 12 gauge ($60 for 100 feet, contractor grade cable) and ten gauge ($90 for 50 feet, extremely heavy duty cable). The ten gauge worked perfectly and mimicked the same voltage created from the generator. It is worth the money.

That's pretty cool (pun not intended)!



I run our 15K AC on a dedicated 20A circuit. Like someone else said, I just make sure I don't fire up the microwave.

+1 to installing a dedicated circuit.

Assuming you can install it near your main panel, the cost should not be that high. IIRC, I paid like $150 for mine? 50A installed by a licensed electrician while I was at work. Just make sure they don't try to wire it like a standard 240V outlet; they need to know it's specifically for an RV.

Kind of funny related story. I have accumulated nearly every adapter I could think of during the 4 or so years I owned my TT. Swore up and down I already owned a 30A Female to 50A Male adapter so I could plug the new MH (30A) into the outlet at the house. Got home and realized that was the ONLY adapter I DIDN'T have!!

It figures though because my TT was 50A, so I only ever needed to adapt DOWN, never UP...
