30 breaker panel ?s jesse 7-9-04  
Hi all, i am ready to wire my bus for electric. i will be powering 1 roof top air conditioner and a couple of recepticles in the bus. can i buy a breaker panel to do this at lowes or home depot or do i need a rv breaker panel. i think ineed a single pole 30 amp main with a couple of 15 amp breakers ??
will a 15 amp breaker handle a roof top A/C ?? any help with this will be apreciated.

thanks jesse

Yes, You can use the breaker panel that you described. Buy one with place for 6 breakers, almost the same cost.
15 amps. will power the A/C. You really don't need a main breaker as the breaker that powers your input power cord protects you.
If you are only supplying your bus with 110V. you will tie the two "line" connections at the top of the panel together. That will give you 110V. on each leg of the panel.

I'm doing the same thing using a box from Lowes, and configuring it the saem as Roger described. You can check out RV Parts Outlet on the internet, located in Oregon. They sell a Marinco shoreline, a 30-Amp connector that mounts in the side of the bus where your RV extension cord plugs in.

RV Parts Outlet also has outstanding prices on rooftop air contioners. Give them a visit. Good luck!

The way I have my elect. panel wired, It is poss. to get 15A, 220V service or two 110V 15A circuits from a site that only offers 110v 15A service.

I have each leg of my circuit panel connected to an 110V 15A male plug, that are located in my lower compartment. ( Plugs A & B)
I run two extension cords to the power source and probe each outlet with a meter, touching the hot terminal (small slot) to another outlet in the same manner. When I find 220V, I plug in my two cords to those outlets. (Connecting Plugs A & B to each cord)
If I can’t find 220v, I use any two outlets (not on the same duplex outlet) and I have two circuits of 110v, 15 amps each. (Connecting Plugs A & B to each cord)
If I don't need more than 15A, I just use one extension cord connected to A plug and plug the other Male plug (B) into an outlet in the coach that is connected to the opposite leg in the main panel. That supplies power to the whole coach.
If you have anything in your coach that uses 220V, you cannot use it on the last connection described above.
If someone switches your plugs, if you are using the 220V.system, you will only have 110v. to your 220v. appliances that will make them inoperative, but will do no harm as there wouldn’t be any currant flow..
If you don't understand this post and electricity, DON'T TRY IT!

Re' Above messages on electricial wireing. DO NOT USE ANY 220V APPLIANCES AS YOU COULD DAMAGE THEM AND CAUSE A SHOCK HAZZARD.
Re: 30 breaker panel ?s Roger Walling 7-17-04  
Upon reading the my above post, I realized that if someone unplugged the cord at the source and you have a 220V. appliance connected and running, It will BACK FEED 110V. to the disconnected plug and is dangerous.

DO NOT USE THIS CONFIGURATION WITH A 220v. APPLIANCE.

I did not realize this when I did my coach, as I don’t have any 220V. appliances
Generator nor shore line produces 110V Jin Ricks 4-1-10  
Can't get 110v from either one.

You DO need a main breaker.

One reason, the supply cord could easily be connected (with a dogbone adapter) to a 50amp supply.
