NC code for Breaker amperage rating in new home for Water Heater, Dryer, Range?


I am Trying to build my own house. I did have it sub contracted to be framed. I am wiring it & I am going to plumb it. I am finding it hard to get a free copy of the NC electrical code online. Can anyone tell me what the Breaker Amp rating is for the Dryer, Range, Water Heater?

This is absolutely not something you will simply find in the code. You need to know the requirements of the appliances, then the code tells us how to figure the circuit ampacity.

Typically:
Dryers are 120/240v, 30A.
Water heaters are 240v, 30A
Ranges are 120/240v, 40-60A

I gotta tell you. If you are not familiar with the codes with regard to wiring a dwelling I would SERIOUSLY consider hiring it out. Simply reading the code book will not teach you anything. It is not nearly a DIY guide.
There are many good books out there for this purpose, but a whole house is something only a WELL seasoned DIY veteran should consider.

lynne, NC uses the NEC - National Electrical Code. There may be specific requirements for your locality and you will have to check with your local building department to find out what they are. And no, they don't offer free copies of the NEC. If you can hold out until the end of September the new 2008 edition will be available, but you'll have to pay the $75 like everyone else.

Some of those books that Speedy mentioned can be found here;

The 2005 NEC IS available online for free.

You can read the it online here:

http://www.nfpa.org/freecodes/free_a....asp?id=7005SB

Click on "I agree.", then "Open National Electrical Code® Softbound 2005 Edition (NFPA 70™)."

BTW- The 2008 NEC is only worth buying or reading IF your area will adopt it immediately, AND you will be staring the job in 2008. If you start the job before 12/31/07 you do the whole job under the code you started with. The new code is NOT retroactive.

Lynne get some books on home wiring and lots of switch diagrams etc and bone up...once the drywall is up and you have something wired wrong or wrong cable ran your going to have a nightmare you would like to forget. An inspection from the code department will not catch branch circuit miswires.
