50 amp down to 110 question

Hey guys, quick question.

So were heading out tomorrow for the weekend, and I'm curious if it's possible to pigtail my 50amp cord down to the 110 adapter and if that's enough juice to run the fridge overnight?

I've got all the pigtails, just never tried it. If nothing else, I'll run it on propane or generator.

You should be able to power the refrigerator off your 15 amp adapter without a problem. But that's all you'll get unless you adapt the 50 down to 30 amps.

Don't forget about your converter...
With all the 12V stuff on it could pull up to 8 amps,
the fridge will need 6 amps to start and about 2 amps running.

Like sundancer said "That's all you'll get" on 15 amps.

These RV refrigerators run more efficiently on LP than AC. I would leave the fridge on propane and let the 15 amp plug run my converter.

I don't think they make a 50 amp to 15 amp adapter. You need to go 50-30 & then 30-15. I did it all the time with the Honda 2000 generator I use to have. I did keep the frig and water heater on propane & ran everything else with the generator. Once I moved up to a 2400 watt Yamaha I could even run my A/C. This was on my 2003 Teton 5th wheel.

The refrigerator is a 'resistive' load, not 'inductive'. There isn't a startup load with resistive loads, it draws what it draws until the thermostat reaches its set point.

Motors, on the other hand are inductive and usually require three times the initial start amperage to get them going and then once running it's only the running amps needed.

I think I have one of these in my stuff.

I wonder how I missed that. Guess because I needed to go from 50 to 30 amps & had one of those, I just bought a 30 to 15 after I got my generator. Or could it of been a 30 to 15 amp was cheaper than a 50 to 15 amp.

Just quoting the chart on the Honda Generator site...

Honda Generators - Wattage estimation guide

"Reactive Loads
Reactive loads contain an electric motor, which requires additional power to start, but significantly less power to run once it gets going. Typically starting power is 3 times the amount of power to run the application. Examples of reactive loads include:

  • Refrigerators / freezers
  • Furnace fans
  • Well pumps
  • Air conditioners
  • Bench grinders
  • Air compressors
  • Power tools"

Are they referencing the start up on the refrigerators inductive 12V fan motors?

Not sure I would take all of Hondas loads as 100% correct. My Yamaha 2400e ran my 15,000 btu a/c with no problem. We could run it, the converter, tv & dvd player & some led lights with no problem. This again is on my 2003 Teton 5th wheel. Did this for eight years with no problems.

Horned Toad,
I would guess that the Honda chart is referring to residential refrigerators and freezers which use a compressor that requires a big oomph to first start.
Most RV style refrigerators and freezers are absorption style and don't use a compressor. I don't claim to know how either works completely, but that is my understanding of the difference.
