Note:
Smoke Detectors are not required to be on a dedicated circuit. Smoke detectors are typically shared on a lighting circuit such as the hallway lights, this way if the circuit is off for any reason it will be noticed.

Robert in Delaware asks: Electrical Circuits
What circuits have to be wired with 12-2 wire?
Dave’s Reply: Home Electrical Circuits
12-2 Type-NM cable is rated at 20 amps, therefore this cable is typically used for general purpose branch circuits such as kitchen GFCI outlets. However 12-2 Type-NM cable is also used for dedicated circuits for various small equipment such as a whole house vacuum system or a clothes washer.

Electrical Project Skill Level:
Intermediate to Advanced - Best performed by a Licensed Electrical Contractor.
Electrical Tools Required:
Basic Electricians Pouch Hand Tools and a Voltage Tester.
Estimated Time:
Depends on personal level experience, ability to work with tools, install electrical circuit wiring, and the available access to the project area. Electrical Safety:
Identify the panel circuit, turn it OFF and Tag it with a Note before working with the wiring. Working in an electric panel is dangerous due to arc flash hazards and the possibility of electric shock.
Electrical Wiring Parts and Materials:
Electrical parts and materials for circuit wiring projects should be approved for the specific project and compliant with local and national electrical codes.
Electrical Codes and Inspections:
Installing additional electrical circuit wiring should be done according to local and national electrical codes with a permit and be inspected.
This is a testing tool that is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
This is great to troubleshoot a problem with outlet circuit wiring, is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets
Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency
Lights indicate if wiring is correct and indicator light chart is included
Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect, Very handy and easy to use.
A wire stripping tool used to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets.
I think your site offers the the clearest and best electrical information for homeowners I have ever seen on the net.You have given me confidence to do my own projects which I never had before. THANK YOU! Paul, from Foxboro, Massachusetts
I wish I found this site earlier, it is by far the best electrical related resource I have found on the web. George, from Scranton, Pennsylvania
I love this site for an office worker that does not know anything about electric wiring. Bill, from New York City, New York
This site is so much better than the 3 books I just bought, I wish I came here first. Collin, from Grand Rapids, Michigan
