50amp & 120 or 220

[Jazzylady]

I have a 220-50 outlet to plug in my Ventana. I have heard it should be a 50amp130.

It should be 110 volts between each of the hot legs and neutral, and you should have 220 volts between the two hots. You should also have 110 volts between the hot legs and ground, and 0 volts between the neutral leg and ground.

50 amp outlet is just 2 branches of 120 volts delivering 50 amps each. So you will have 100 amps total available. It is supposed to be 240 volts across the 2 hot leads (outside terminals) but occasionally it will be only 120. Some rigs need the 240 volts, so if you do, best to check with a voltmeter before you hook up.
Happy Glamping.

Test with volt meter . As per diagram .

USE only an outlet that looks like the one shown!

Please read before plugging into that outlet........

Verify that the outlet is an 14-50R outlet wired with 2 hots, 1 neutral and 1 ground

The plug on the end of your power cord may be marked 120/240 volt - 50 amp. That's what you need.

It's the same plug used on an electric range.

It's explained here,

http://www.myrv.us/electric/Pg/50amp_Service.htm

This*50-amp*service*has 4 wires with two 120-volt HOT feeds.*It is a*misconception*that this 50-amp RV service is something special.*This service is a STANDARD 120/240 50-amp 3 pole with 4 prongs used for*numerous*applications.

We plugged in our our house 50 amp plug using a 50/30 + Standard Plug adapter for about 1 hour this weekend, to cool down the refrigerator, while we loaded up to relocate temporarily for Irma. We used an exterior extension cord (orange) which we normally use for lawn equipment as it was the largest gauge we had.

When we went to disconnect, we found the cord very hot!

In the future, is there another gauge extension cord I should use, or just run the generator while loading?

As others have said the wiring is identical to that for a 240 Volt electric range or clothes dryer.
If not 100% certain, test it, test, it test it or have it tested.

Had the same problem and replaced with this cord. Can run one AC and the refer without a problem but need a different adapter (30/20 amp).

Look at the cord itself. It should be marked every foot or so.

Look for 12/3 gauge. If 16/3, like the picture, that's no good, sometimes a 14/3 gauge will work just for the fridge.

I have a 75 foot 14/3 cord that I use to keep power to our rig. I can turn on my fridge 24 hours before we head out, the cord never gets hot.
I suspect that when you hooked up, the battery charger kicked in to the high amp mode. That and the fridge probably put the extra load on your extension cord. My charger is in float mode when I turn the fridge on, so only around 400 watts draw (3 1/3 amp @ 120 volts).
If possible, try to have your rig powered up for a few hours before you turn the fridge on, that way it should be in float mode on the charger.
I have a read-out on the MH control center that shows me how many amps the rig is using at any time it's hooked up to anything other than a 50 amp service.
Happy Glamping.

Well...I never thought it would happen.

We are in Mobile, AL... at "The Grounds". Home to the Greater Gulf State Fair.

They have very graciously hosted a little more than 75 rv's evacuating from Florida during Hurricane Irma.

They actually have TT-30 outlets...wired to 50A breakers. So we actually have single phase 120v 50A power.

Of course, our energy mgmt system detects single phase as 30a...and is load shedding unnecessarily.

Don't know why...but that's the way they decided to wire thier outlets.

The 30 Amp outlet is only good for 30 Amps. Your plug that you plug in is only good for 30 Amps. Don't use it for more than 30. The 50 breaker should not be there.

For 30 amp the cord should be #10 , 50 amp #6 . As well as getting hot , you will loose quite a bit of voltage in a smaller cord.
For just the fridge and a few lights, #12 should work OK. Just remember that he inverter will be trying to charge the batteries while plugged into shore power.
