I do just fine with my 50 amp service and autoformer until I get into a state park with only a 30 amp. I also understand how a 240 service can split into two 120's and feed different curcuits 120. I guess I'm just trying to understand why they just don't call it a 100 amp plugin instead of a 50 amp plugin?
It is called a 50 amp service because it has 50 amps of 240 volt power available. Think of 120 volt power as a two or three wire plug like you normally find in your home. A two wire plug will have a L1 (hot leg) and a N (neutral) wire to carry the current. A three wire 120 volt circuit (like most 3 prong cords in your home) Will have L1 (hot leg), N (neutral) and G (safety ground).

A 240 volt circuit consists of two 120 volt circuits at opposite phases (think of a sine wave). These are L1 and L2. When you connect them together, you get 240 volts, connect one of them to a neutral and you get 120 volts.

For a three wire 240 circuit (like a welding machine) you have L1 (hot leg), L2 (hot leg) and G (safety ground). If you are going to a modern, 240 volt appliance (like a clothes dryer) that requires a 120 volt control circuit, you need 4 wires. Those will be L1 (hot leg), L2 (hot leg), N (neutral) and G (safety ground). That way you can make a 120 volt circuit (L1, N and G) or a 240 volt circuit (L1, L2 and G) from the 4 wires.

Note that in a 120 volt circuit, you can use either of the two hot legs (L1 and L2) as both will give you 120 volts when made into a circuit with a neutral. Like noted above, if you look at your pedestal, there will be a double 50 amp breaker that has each hot leg attached (L1 and L2) running thru each side to give you the 50 amps of 120 volt power on the first breaker and 50 amps of 120 volt power on the second breaker.

I sure hope your campground owner isn't the site electrician as well.

I'm getting an education! Thanks for explaining that and sorry original poster, didn't mean to hijack your thread! I have no idea if the owner wired this place but he was telling me about all the inspections he had to go thru. Like a new well and a $3,600 water test, that's insane!

Couldn't put a 3rd on our 36RSSB3, was told that from manufacturer, but 2 have worked for us thus far.. unit much shorter than yours

Rolling Retreats even puts 3 AC's on the 32' units.

OK, being the stupid one in here, I purchased mine off the lot. I've never ordered one.."Supposedly. When I asked to have a 3rd one put on at Dealership, THEY're the ones that told me that a 3rd one couldn't be put in.. Probably because they were too inept?? I was too stupid to know better I guess.

All,

Refering back to my earlier Post (#14 this topic), as of noon today the replacement AC has been installed on our 2 year old (purchased on 30May15) 2016 Vegas 24.1...and all done under warranty.

I would agree it would be a MAJOR job to add a 3rd AC and have it ducted like the rest of the system.

Hats off to Mohave RV and Marine in Bullhead City AZ. Went in a week ago yesterday in the afternoon about our dead AC. They ordered it under warranty on Monday had it shipped 2 day and installed it Thursday. No charge for the 2 day. We hit the road for the summer on Tuesday...

That's how service should be!

Enjoy your Summer.

The middle a/c is tripping a breaker on my ‘14 39RESB3. The breaker was switched for a new one and it tripped again. I’m thinking that it is the a/c start capacitor. Anyone know what the part name/number is on the caps for these a/c’s?

The new units are $800. So even fixing one for $200 is worth it. Finding a leak should not be hard on these. It is a small system. Push some die in and run for 20 minutes. Go over with a black light to look for die.
These units only hold 17-23 ozs of R410A.

Ryan,
Thought these ACs were sealed units--how do you get a dye into the gas lines?

I thought that she did a 3rd AC prep. Meaning the ducting was prepped to except the 3rd unit and pre wired. Slade installed a 3rd unit once and was told never again.

You would have to add a high and low side service port.
If I see a guy in a park I am staying at I will ask how much to add service ports and evac and recharge.

Therefore, 50 amp service can provide 120 volts x 50 amps/hot leg x 2 hot legs = 12,000 watts.

30 amp service, on the other hand, has only 1 hot leg. Therefore, it can provide 120 volts x 30 amps/hot leg x 1 hot leg = 3,600 watts.

you are total wrong.... you try pulling 100 amps of power off a 50 amp breaker and you will blow it right off the pedestal... the bridged 50 amp breaker is the amount for both sides combined...and they are tied together...so the amp rating is on the breaker switch....that's the max...50 amp...next,... you have a hard time finding someone who would put wire size capable of pulling 100 amp on a 50 amp breaker...

You can't talk about amps without talking about volts:

30 Amp RVs use 120 VAC for at total of 3600 VOLT-AMPS.
50 Amp RVs use 240 VAC for at total of 12000 VOLT-AMPS.

But since the 50 Amp RVs split the two hot legs to utilize two 120 VAC circuits, each 120 VAC circuit can utilize its own 50 amps, essentially giving you 100 Amps of power at 120 VAC - which still adds up to 12000 VOLT-AMPS. Sooooo, not so wrong.

Just repeating what she told me right to my face.

I can tell you from the years I have read RustyJC's posts he has NEVER been wrong!

I personally run WELL over 40A on each leg on my 50A breaker!

Three AC's, washer n dryer water heater etc.

oh yeah???? well... I think I'm the one wrong here....LOL been thinking about this all night,...my 2 brothers that passed away were electricians, years ago I roped house s , but always worked as a helper... what I think is the rv is just a sub panel off the CG power... so in theory... you could sub as much as what is coming in....I just built a RV garage in havasu that I put a 400 amp service…..had to change out the cable size to the pole as it was org. set up for 100 amp service … the 50 amp from the CG pole goes to the 50 amp sub panel in the RV.... it is then split to 120 volt breakers, sure you could keep adding breakers... or use piggy backs to load even more..... but you are not pulling 3 ac's, washer, dryer, water heater, off one breaker

so again, I have to admit I was the one wrong here in theory....as in I probley am the one that doesn't know what i'm talking about and am very dangerous right now... the most dangerous guy is the one that thinks he knows something....
