Methods of Electrical Wiring for a Shop and Light Fixtures: I'm building a shop and have some electrical wiring issues. [ad # block] Formalized paraphrase I'm building an auto shop and have some electrical wiring concerns. The first thing you should do is determine whether or not the space you are working in has been wired with electricity. If it has, then there is no need to redo the wiring inside the shop area. You will only need to run new wires where they are needed within the walls and flooring.
If the space has not been wired yet, then you will need to take care of that before you start work on the interior of the shop. A licensed electrician should be hired to do the work of wiring your shop properly. However, if you are comfortable working with electricity then you can also do the job yourself. But, before you begin work, make sure you understand how to perform all the tasks involved in a safe electrical installation.
First, turn off the power at the main panel box located outside near the street. Then check all the cables connecting to the various equipment in the shop (jacks, amps, etc.) for loose or broken connections. Make sure any metal parts of the equipment (fans, heaters, air conditioners) are securely grounded.
Next, remove the cover from the main panel box.
Let's go through five stages for choosing and designing the optimum lighting for your shop area.
An Electrician Describes Wire Size for a Workshop Circuit. How to Install Workshop Electrical Wiring with Diagrams and Photos demonstrates Blueprint Layout and Electrical Code Requirements. How to Install Workshop Electrical Wiring with Diagrams and Photos illustrates the proper procedure for determining wire size for panel and device circuits. The correct terminology for describing the thickness of copper wires is "gage." The word "wire" is used here to refer to all types of conductors, including aluminum, which will be discussed later.
The term "main panel" refers to the large power distribution center on the floor or wall of a building where various components of an electric system are located. These include circuit breakers, fuse boxes, meter stations, and more. The main panel is the central point at which electricity from the utility company enters the building and is distributed through out-lets (or outlets) called branch circuits. A load is anything that uses electricity, such as lights, heaters, air conditioners, and appliances. Power flows into the main panel, passes along different paths until it reaches these loads, which use it up. Then it is returned back to the main panel through other branches or circuit breakers.
Circuit breakers protect equipment by shutting off power before any damage can be done if excess current flows in an electrical path.
What wiring method will be utilized in the workshop? Wiring should be nonmetallic encased cable, Type MC cable, or electrical metallic tubing (EMT), unless otherwise specified, and shall be suitably sized and installed in accordance with the most recent version of the National Electrical Code and local legislation. If no size is specified, then 14-gauge wire should be used.
The wiring method determines what tools are needed for installation and maintenance of electrical systems. Nonmetallic wiring is easily worked with metal working tools such as wiresaws, screwdrivers, and pliers. EMT requires special equipment to cut and strip its outer casing without damaging the conductors within. The type of cable used affects the design of the building structure required for adequate ventilation.
It is important to use the correct wiring method when installing an electrical system. Incorrectly applied cables can cause serious injury if not detected during construction. Professionals are available to help you determine which wiring method is best for your project.
The Fundamentals of Device Wiring Many of the same fundamental strategies are used when wiring electrical outlets (technically called receptacles) and switches. Making secure, long-lasting connections necessitates correctly preparing the circuit wires that will connect to the device and firmly attaching each wire to the appropriate terminal. Proper preparation requires removing any insulation from the ends of the conductors so that they will make a clean connection with the metal parts of the outlet or switch. Wire connectors used for connecting conductors in an extension cord or tripping conductor in a lamp cord should be large enough to make a good connection without stripping off too much material. The term ground means exactly what it sounds like: a path to the earth or ground. All electrical systems have a ground connection in one form or another. It may be a third conductor in parallel with the other two (called "third-wire ground") or it may be a metal box or fixture on the floor or side of a building. The function of the ground is to carry away any electricity that might otherwise damage people or equipment.
In general, all household electrical outlets and many other devices have three sets of wires coming out of them: one black, one white, and one green (or red). These are the live wires, which should never be touched. The black wire is always considered to be the "hot" line, while the white wire is the "neutral," meaning it provides no power but does not carry any current to ground either.
