Ok guys, already have 200 amp service for small camp ground, trying to run lines for 12 camp sites to pull 30 amp service, each site will have a RV which will be running ac all summer, what do I need to do,can you add a 200amp sub panel please help??

This is a sizable project well beyond a DIY'ers realm of a homeowner doing their own work at home. This is serious commercial installation dealing with innocent customers.

There are many code requirements to research, voltage drop calculations to size each feeder,and product choices needed depending on various conditions.

While there are many knowledgeable experts here, including myself, this is not the place to layout and design a system such as this.

Sure when all done it may look simple. I can give you one wrong number and cause great damage. Now if you want to spend the couple of hours designing. Layout and calculations , and get back with a design, then we can talk about something specific.

You should be able to hire an electrician to do all the design, and let you do most of the bullwork, have him come in and do final terminations, inspection, and sign off.

I agree! Heck, even I would have to sit down on this one:D

I agree with tk, but I want to mention a few things. 1) There are specific RV pods available. They can include internet phone and cable as well.
Take a look around a Midwest Electric Products, Inc..

I don't understand the 200 amp sub-panel question. The most likely maximkum size of a sub-panel is 100A because there probably isn't a breaker larger than 100 A available.

If your increasing service is another thing. Say going from 200A to 400A.

You will need to know the distance to each POD to the service panel.

The voltage drop calculations are not hard, but someone needs to sign off on it and wire has to be buried 18" deep.

There is a load calculation.
There is design.
Parts selection.
Design on paper.
Design approval.
Permit.
Grunt work.
Final termination.
Inspection.
I'm not sure your willing to take on this amount of work, Could be wrong, though.
