AMPS 20? 30? 50? Which One Do I Want?
I guess this may seem like a silly question ... but I'm still trying to figure all of this out and I'm still learning. When I am making reservations for a campsite with electrical hookups, I am typically asked what electrical AMP service do I want? 20? 30? 50?
I assume that I would want 50 AMP if it is available because it would allow more electrical appliances to operate? Or this assumption incorrect?
Is there a problem with the use of a lower AMP service or is there a risk of negatively affecting any appliances with the use of a lower AMP service?
We have a 1988 32 ft. Airstream Excella that we utilize the electrical hookups on. I haven't been able to find anything in the owner's manual that discusses this subject. Thanks in advance for educating me on this subject.

Look at the 120VAC electrical breaker box. Confirm what the largest amperage circuit breaker is and that is the maximum amount of load that can be drawn through the wiring of that box. For most trailers that is 30 Amps. If you use a 15 or 20 amp cord adapted to a higher rated service and try to pull more amps then the cord is rated then you could start a little fire.

I am pretty sure that the 88 still used the 30 amp service.
20 amp is little more than a household plug in.

If you can, take a picture of your plug and post it, that may help. The style plug will dictate the service you need.
You can think of Amperage like a water hose. The higher the number, the bigger the water hose. Our Airstream has a 30 amp plug, but I have used 20 amp service, with an adapter, but that does not allow me to use the A/C and microwave - basically just lights and battery charging.

Almost always in the trailers made since the '70's at least, 30 amps is the norm. This is true for Airstreams. 50 amps is used in motor homes. You have 30 amps unless the previous owner rewired your trailer. IIRC, even 34' Classics with two A/C's have 30 amp service and can only use one of the A/C units at a time. This may have changed on the most recent models, but I don't recall it being different.

Thank you all for your replies. It's starting to make sense to me now. I'll take some photos this weekend and post them.

I put in a 45 amp which I bought on sale. I was looking for a 30 amp, but I got a better price on the 45 amp. I would not go higher then 45.
