50 or 30 amp

[daydreamer]

I am starting on the electrical part of my tralor.Question on amps,I will have a 5000 btu airconditioner,coffepot microwave ,small refrig,tv,and one machine for my sleep actnea i have.what would i need 50 or 30 amp service? I bought a small electrical box,1 20amp breaker an 2 15 amp breeakers. So should i buy a 50 amp breaker for my main or a 30. I was thinking about putting the airconditiner on the 20 amp breaker by itself an runing the rest of the stuff off of the 2 15 amp breakers.would this be right or can i run every thing off of just 30 amps. LOL MY TRAILOR STARTED OUT TO BE A TEAR DROP ,BUT my better half wanted something she could stand up in,so the front part is tear shaped an the back part you can stand up in. I will get my son-inlaw to post a picture of it later. Iam areal dummy when it comes to to this.

30 amps for the main should be more than adequate...the AC is going to pull around 5+A running and maybe twice that for a blink at start up...the microwave will pull under 10A and everything else together would pull no more than that...a couple of 15A breakers should be just fine...unless you plan on welding while camping...

I'm with Madjack - hey we could weld with the 50 Amps. You'll usually find 50 Amp service on those 55 foot Klingon War Cruisers going down the highway - you know, the ones towing an escape pod?
Jack's the man...........................

Daydreamer, if I remember my codes correctly, if you were building a house, you would need a dedicated circuit for your AC unit(20A breaker). Everything else, like Madjack and Sierrajack said...

This original design looks good to me, although if the air conditioner is small I don't know why it needs a 20 A breaker.

...would this be right or can i run every thing off of just 30 amps.

Although the total of the circuits is 50 A, the whole panel with the three breakers can run on a 30 A supply and main breaker. There is no need for the main breaker to support the total of all branch circuits simultaneously running at their maximum individual currents, unless you might really be doing that. For instance, my house has 100A main (double) breaker, and the branch circuits total more than 100A per side. I'm sure there's a guideline for the ratio.

The usual reason for 50A @240V RV service is to run two large air conditioners, plus all the other electrical toys. That's pretty common even in less-than-WarCruiser size motorhomes. Some people cook electrically (instead of propane), and that drives them to big service, too.

With a single A/C and no electric stove, even 30-foot travel trailers typically have only 30A @120V service... so it should be enough for the teardrop!

Hijack!

I never thought of it before you posted it, but the shuttle pod from the Enterprise would be perfectly adaptable to trailer design. And with the pontoons on the side, the elusive floating camper.

And now, back to our regularly scheduled topic to which I reply, "yeah, what they said."
