I am installing and new mast and meter plug in addition to a main disconnect. I was trying to find a diagram online that shows max and min height requirements for installing these. I realize that I should check with my local inspector but I just wanted to get an idea of how to install before I talk to the local inspector. The city I live in uses NEC. Thanks in advance for your help.

Can you access NEC on line? Some of the other sparky members will reply in depth shortly.

Not sure what Zipper's busted link might have said or shown. No single page of the NEC is going to provide the answer. The problem is that there are so many quirky combinations of things that it is hard to give a good answer. Do you have a decent public library near you? The best advice I can provide is to see if they have a good code comentary book and to look at the pages around paragraphs beginning with the digits 230, There should be some good pictures to go with some of the explanation. If I knew the specifics of your situation, I could better provide meaningful guidance. Would need to know whether the weatherhead will be above or below the roof; if above the roof what the slope of the roof is; whether the aerial drop will be at all close to any windows; whether it crosses any driveways or out-buildings, and what the voltage is. (I'd presume we are talking 120/240. EDIT --- Check your private messages. I need you to e-mail me.

When I started building my house 8 years ago, I called the electric company to ask about conduit size and meter height and other questions. They sent me a book with all that info. and more for free.

That is most definitely the best way to go. Contact the power company who supplies you. They will have the minimum requirements for your area. They can and sometimes do require more than the NEC. I can usually find the publication the power company uses on their website. You could also check with your local code enforcer or town office, they may have a copy of the power companies installation requirements. You will probably also have to fax in a form for the power company to come and do a disconnect/reconnect. They may even allow you to do your own disconnect/reconnect but they will still need to know that you are doing it and when you are complete so they can do their permanent splices.
