50 amp to 30 amp

ryansmousehouse · 03-08-2008, 08:54 AM

the campground I'm staying at only has a 50 plug at the site ....My winnie is 30 amp. Is there a problem with using the 50 amp outlet (I've got the camping world 50 to 30 cord)...thanks, bob

Shouldn't be a problem. Your circuit breaker in the rig will trip if you get too hungry for electricity.

That is exactly the situation the 50 to 30 dogbone adapter is for. Go for it!

A 50 amp has two legs, a 30 amp and a 20 amp. the 50-30 amp dogbone just uses the 30 amp. same as if you are plugged into a 30 amp site.

No problem at all. I used to do it all the time when I had my 30 amp C Class. No damage what's so ever.

A point of (I hope) clarification:

A 50-amp service has 4 connectors:
Two are "hot",.. One "Neutral",.. and.. One "Ground".
Both "Hot" legs are 110-volts (relative to the neutral),... however on 'opposite cycles' so that there is 220-volts if you measure across them.
Both "Hot" legs will normally carry up to 50 amps each.

The dog-bone adaptive connector (from the 50-amp source to the 30-amp user) does "not know" which leg is which.
It simply uses one "hot", one "neutral" and one "ground".

EXACTLY!! ...a real 50a outlet will have two legs with 50a each, for a total of 100a. There are some so-called cheater setups that try to make a 50a connection by combining one 30a and one 20a into a 50a. That may get you 50a, and may work better than 30a, but it won't get you real 50a service!

Sorry, I stand corrected.

Hmmmm....
A point of clarification.
As a retiriree from a Electric utility I would like to perhaps shed some lite on a voltage level of 110 Volts. 110 Volts is a voltage level that was supplied (I think) in the 1920's untill perhaps the 1950's. We would find some very old transformers that had a secondary terminal (low voltage) rateing of 440 volts (thus 440--220-110 volts). The nominal supply voltage for most electric utilities in this day and age and thier residential and light industrial customer's is 480Y/277V & 208Y/120 volts for three phase customers and generally the residential customers the single phase nominal voltage supplied is 120/240 volts

The only time one will ever see 110 volts is when there is a problem. The utility has guidelines that state the high and low of the supply voltages supplied and can be made fininancially responsible for failing to maintain voltages within those guidelines. That being said, the campgrounds we as RVers frequent have pretty big distribution systems and if they are lacking maintenance or in a high demand time the voltages can and do dip well below the recommended voltages.I use a surge guart to protect my coaches electrical system but as of yet I have not bought an autotransformer. Its on my list of thingies to purchase in the near future.

Some of us had parents that lived on farms before electricity was available in the rural areas.

I still refer to 110v, as that's what Mom and Dad always said, even though I'm well aware it's 120v now.

Old habits are hard to break.

Like Dirk, I grew up hearing "110/220", even though line voltage was a nominal 117VAC. Even those electrical engineering classes in college weren't enough to purge it from my vocabulary.

as codgerbill says, always use a "surge guart". u can get a plug in PROGRESSIVE 50 amp surge guard for about $100, A 30 amp for a little less. camping world has another brand that is not avail in 50a. cheap insurance.
