What does and Electrician do?
Electrical contractors work with blueprints when they install electrical systems in factories, office buildings, homes, and other structures. Blueprints indicate the locations of circuits, outlets, load centers, panel boards, and other equipment. Electrical contractors must follow the National Electric Code and comply with state and local building codes when they install these systems.
In factories and offices, they first place conduit (pipe or tubing) inside designated partitions, walls, or other concealed areas. They also fasten to the walls small metal or plastic boxes that will house electrical switches and outlets. They then pull insulated wires or cables through the conduit to complete circuits between these boxes. In lighter construction, such as residential, plastic-covered wire usually is used instead of conduit.
Regardless of the type of wire used, electrical contractors connect it to circuit breakers, transformers, or other components. They join the wires in boxes with various specially designed connectors. After they finish the wiring, they use testing equipment, such as ohmmeters, voltmeters, and oscilloscopes, to check the circuits for proper connections, ensuring electrical compatibility and safety of components.
Electrical contractors also may install low voltage wiring systems in addition to wiring a building's electrical system. Low voltage wiring involves voice, data, and video wiring systems, such as those for telephones, computers and related equipment, intercoms, and fire alarm and security systems. Electrical contractors also may install coaxial or fiber optic cable for computers and other telecommunications equipment and electronic controls for industrial equipment.

Why hire a professional electrical contractor?
You should also be aware that due to codes, you might not be allowed to perform electrical work yourself. There are so many little details that must be considered when wiring or establishing new electrical components and without the proper knowledge, licensing or training, you can easily overload a circuit and cause more damage.
If you need to hire an electrician, you must make certain that they are licensed and insured. Check with your local state's requirements and certifications and ensure that the electrician that you've contacted has met those requirements. The electric contractor should also get the proper permits for your project as well. By calling your state's department of labor you can find out what the requirements are that your electrician will need to meet.
How do I find a good electrical contractor?
Look for an electrician with a license to do work in the City of Philadelphia. Many municipalities have registration or licensing procedures for electricians, but this can mean nothing more than the person has paid a fee. The Philadelphia license requires that electricians have met education and experience standards and have passed a code examination granting approval for a journeyman electrician to secure an electrical permit.
Check for insurance. Ask to see an insurance certificate, which means the electrician has met the industry standard for insurance coverage.
Ask for references and check them out. Talk to family and friends who have hired an electrician recently. Ask about their experience. Would they hire the same electrician or company again?
