With our equation we would see 50A x 120V = 6000 watts

From this you can add up the load of power in watts of each load and determine how much capacty you need in watts for a generator. A 6000 watt generator should carry enough load to support 50 amps of load.

To muddy the water somewhat, your 50A service is really 2, 50 watt legs which gives you a total 100 amps or 12000 watts of capacity.

But in real life, even running all 3 generators, fridge, TV, etc, I can't imagine the steady state load exceeding 8,000 watts or so. The most load I'ver ever seen on mine was 65-70 amps incoming, or around 8000 watts. Most of the time it is much less.

And for what it's worth, a generator makes electricity (either AC or DC), an inverter uses DC power from the battery to make AC.


Thank you Rampowerwagon. Best description Iíve read in a long time.

It is. Itís actually too much for the RV but we can use it for the house also. Click image for larger version

Do I not remember that the new Predator generated is rated at 57 dB? I believe that is same as Champion and very close to Honda.

Iím not a fan, just curious.

Generators start getting heavy, bulky and expensive as the power capabilities go up. A little power conservation goes a long way.



And as rampowerwago posted check the watts (power) of the appliances you want to operate to determine how to size the generator. Heating, cooling and the microwave are high demand items. TV's and such are minor. The fridge is a low power appliance but will have a start surge that can push into 20 amp range for a second or so. Same for an A/C compressor but the generator should be able to make past those instances unless they both cycle on at the same time which would be very rare.



I can run everything, except both A/C's and the electric side of the water heater, at the same time with a 3600 watt generator. Got a strange coach in the driveway. 50 amp service with a 30 amp generator.


Sweetbriar, can I ask, which brand 3600 you own? And would buy the same again?

Some good information and wishful thinking on this thread

How many electrically powered items will you be running at one time? Not the furnace, fireplace and a/c at the same time for sure.

You learn to do power management with 2-4000 watts or just buy big. Most folks can physically handle that size hauling it in and out of the TV. A permanent installation in the RV - well best make sure that the Lippert frame was built for a heavy genset. Our 65 pound, 3600 watt inverter generator will run almost everything very nicely but not all at the same time. The HW heater is a power 'sucker' - we use propane. We don't always need that second a/c either. And my DW knows that something needs to be turned off if she is using the hair dryer. This is camping, not a week at a luxury hotel or even glaming

I like your answer IC2. I have a CC 34 RLSA 50 amp. I have a 3500 Champion with remote start and before someone gets all offended it is as quiet as any inverter out there. We boondocking a lot and it powers what we need nicely. We also found on our cross country trips that alot of smaller town parks and a lot of older campgrounds only have 30 amp service. To the OP you will learn in short order what 30 amps will run. We have found that 15 amps is doable once you understand power management. Good luck.

How can you tell if a particular RV has 50 amp or 30 amp service? I can't find it in the specs. Should I have made this a new question?

30 amp three prong plug. 50 4 prong plug

Yes, but i'm talking about when I'm comparing / considering different RVs. I don't see a spec that tells which it is.

Most newer models will be 50 amp. Good indicator is if it has 2 a/c it will be 50. Residential frig. On demand hot water heater.

- If it has an exterior power socket. 30a = 3 conductors, 50a =4 conductors. -
- The power distribution panel will have either a 30 or 50 amp breaker
- If the salesman has any intelligence, he either knows it's 30 or 50 amp or he can look at the spec
- If the power cord weighs a LOT and is pretty stiff, it's 50A. Light and flexible, 30 amp
- Two a/c units or at least wired for two = 50a

I'm talking about looking on line / researching different RV's. I know how to look at a plug.
