Although all cities or municipalities have their own building codes which vary by degree, the typical electrical building codes noted here are often found. Some electrical building codes are general to the home overall; others are very specific depending on the rooms purpose.
This article will list common ones.
The points made in this article provide common electrical building codes. Check out your local codes for specificity.
Understanding home wiring is important before doing any modifications as well as new installs. And, be aware that an electrical construction permit is usually pulled at your city hall or another municipal building. Periodic inspections will be made by the electrical building inspector.
Wiring for Bedrooms, the Living Room, and the Dining Room
Note that it is no longer acceptable for the main ceiling light to be activated with a pull chain; it must be a wall switch. A ceiling fan light may have a chain but it still must be connected to the switch.
Each of these rooms has at least one entry door. Install a wall light switch near it.
Your light switch must turn on either a a switched receptacle or a ceiling light fixture.
Every wall shall have a minimum of one electrical receptacle. But there should be more than one for convenience; there shall be one available every 12 feet.
All light fixtures shall be on a 15-amp circuit.
The Electrical Building Code for Your Kitchen
The electrical building code for your kitchen is quite a bit more complicated than other areas of the home due to all the appliances.
Generally speaking, receptacles that are above countertops and used for small kitchen appliances must be GFCI receptacles, controlled by two 20-amp circuits.
Other receptacles are on 15-amp split-circuits.
More sizable appliances like the garbage disposal, refrigerator, and dishwasher may need to be put on dedicated circuits.
All kitchen lighting is on its own 15-amp circuit.
Electrical Wiring for Your Bath
Wiring a bathroom is simple. Since the bathroom is a wet area, youll be required to provide GFCI-protected receptacles.
Lights shall be protected with a globe, lens, or something similar to keep moisture out.
Depending on the amperage you consume, heaters, lights, as well as exhaust fans shall be on their own circuits.
Code Standards for Outdoor Applications
Any outside wiring is open to the elements. Because of that, either underground feed cable (UF) or sealed conduit shall be used.
How deep should the conduit be buried? Thats something thats dependent upon local code. Investigate your local code.
All fixtures shall be tightly sealed to keep water out. No-brainer here, folks.
Interestingly, in some municipalities, no building permits are needed for the installing low-voltage lighting. Expect this to change.
Wiring a Closet
Closets are basic wiring jobs. One ceiling light shall be installed; and like your living room, pull chains arnt allowed, but a wall switch shall be used.
Attached Garage Electrical Codes
The overhead light requirement is the same as for the closet.
These typical electrical building codes should get you started on your project. Just be sure to use a licensed electrician and pull permits when required to do so.
