1. Recessed Electrical Boxes
Sometimes adding paneling to wall surface can cause code violations. Use extension rings to solve the problem.
2. Wiring is not Properly Secured
Some trouble will be present if staples are driven too tight to secure the wire to studs or beams. The wire can be severely damage, if it is not properly attached.
3. Wiring Size
One of the most common problems and one of the most dangerous one. Using an improper wiring can cause the wire to overheat.
4. Wiring Length
Code regulation is specific about how much wiring can be stripped. At least six inches are recommended to facilitate handling of the outlet box.
5. Protect Wiring
Unprotected cable can be damaged. Electrical cable must be covered and protected if it is widely exposed to the public, and if it is exposed to harsh weather conditions.
6. UF Cable
UF cable MUST be protected inside a conduit. This cable commonly used to bring power to other areas, but it is frequently used as an exposed wire, leaving it prone to damage.
7. Connectors
A cable connector must be used to keep the metal from damaging the cable sheath and causing a short circuit.
8. Connection
Remember each wire has its function either the neutral, the live current, or the ground; each one of them must be properly connected and never leave without connection.
9. Replacing Wires
NEVER replace a two-wire receptacle with a three-wire receptacle. Exception: A two-wire receptacle can be converted to a GFCI receptacle.
10. Lights
Do not replace light fixtures in older homes without a grounding conductor. Replacement of light fixtures requires grounding if a metal fixture is installed, or install GFCI protection on the circuit. Non metallic fixtures may be replaced without grounding.
11. NEC
Most important of all-Remember to follow all recommendations and follow all standards as set forth on the National Electrical Code, latest edition.
