| Appliance troubleshooting
If an electrical device won't turn on, first make sure it's securely plugged in. Also, check the cord for fraying, overheating, or soot. It could be that the plug is defective, or a new cord is needed, usually a job for the electrician.

| Circuits
Every time you flip on a light, you're seeing a circuit at work. In scientific terms, a circuit is the complete path that electric current takes, as it travels from a source, along the wires, to the device it's operating, and back to the source.

| Different types of electrical service
Whether you're building a new home, or renovating your current place, a good electrician can provide many valuable services. They can help you plan for a complete lighting system, indoors and out, run the wiring for a home theater, and install security lighting.

| Electric heating and A/C troubleshooting
Electric heating and air conditioning systems are complex devices, that usually require professional repair. However, there are some steps you can take, before calling an electrician.
|
| Emergencies
Two of the most common electrical emergencies are fires caused by overheated wiring, and electrical shock. A wire that's exposed or forced to carry more current than it can handle becomes a hazard: without protection from a fuse or circuit breaker, current continues to flow, generating heat, and starting a fire.
|
| How to identify electrical problems
The most severe electrical problems will identify themselves, and sometimes dramatically: the television suddenly emits a loud pop, and goes black. You flip on the air conditioning, and the whole house suddenly loses power.
|
| Rewiring and repairing
Rewiring a home is a complicated task that requires special knowledge; therefore, it's usually best handled by a professional. The same goes for major electrical repairs, like panel upgrades or faulty appliances.
|
| Underwriter's laboratory
Underwriters Laboratory is the best-known testing laboratory in the united states. This not-for-profit organization sets standards of safety for many electrical devices, and tests products to determine if they comply with those standards.

| When do I need an electrician?
When do you need an electrician? That depends on you, and your local code. In some areas, the homeowner is limited in the types of electrical work he or she is allowed to perform.
