Remember that wires of the same color connect to each other. Basically, electrical wires are color coded to prevent wiring errors. White wires are normally used to connect to other white wires or to chrome terminal screws on switches and receptacles. Black wires in the cables are intended for connecting switches. However, there are cases where a cable is extended. If this is the material, white wires are often used instead of black wires. To be able to prevent future wiring errors, try to paint the white wire black.
Electrical wiring diagrams that are in color have an advantage over ones that are black and white only. The wires will be colored the same as the actual wires you will be using. Commonly, the green wire is ground, white or off-white is neutral, and black, red or other colors indicate the hot wire. In some instances, such as some switch legs, the function of the wires will be indicated by colored electrical tape. When looking at any residential wiring diagram, start by familiarizing yourself with the symbols that are being used. The electrical symbols will not only show where something is to be installed, but what type of device is being installed. Make sure you understand the symbols on your diagram before beginning your project. There should be a chart on your diagram showing the different symbols being used, much like a legend on a map.
There are different voltage levels for different components in a house. For example, a phone or doorbell system would be considered low voltage because they use around twenty-volts with really low current. Lights and outlets require 120-volts with up to 20-amps of current. The bigger electrical circuits require heavier cable. They usually require 240-volts with up to 50-amps of current. The electrical circuits need to be planned out well in advance when the blueprints are being drawn up. I prefer to have about 40 copies of the floor plans in a notebook. I draw each electrical circuit on its own page of floor plans. This helps keep the circuits separate in my mind. The electrical blueprints can be very confusing especially if you do not know how to read blueprint symbols.
Bulldog.com offers a basic explanation of electrical information in an MS Word document; however they do not supply charts or schematics. Two other sites that I found to offer great information were Freeauto.com and 12voltresource.com. Freeauto.com provides complete color diagnostics for most makes and models. What I found interesting(?) is freeauto will provide you these color automotive electrical charts and all the other information on their informative website for $11.99. They also assist you with basic electrical theory, electrical harnesses and test equipment.
Most notably, while utilizing residential electrical wiring does not forget one essential saying "Electricity can kill." It is vital you fully respect it when focusing on electrical wiring in your home. In many municipalities do not even be allowed to operate on it, and generally you will need a permit at least. Within my experience local building inspectors provides homeowner has permits for small projects once they present an electrical wiring diagram plan that will demonstrate some level associated with basic electrical wiring understanding.
Install the GFCIs. The ground-fault circuit interrupters are a must for affirming the electrical safety in wet locations. They cut the power to the circuit when there is a power short. They reduce electrical hazards significantly. Determine the best height for the receptacles. You will need to install them at heights comfortable for you to reach. For example, place them at the waist or desk height if you do not want to bend over to plug or unplug everything. On the other hand, a knee height makes sense for items such as floor lamps, TVs, etc. If it is a workshop, install them higher on the wall than in a home setting. Such a place uses lots of small power tools, and higher outlets are convenient for plugging and unplugging such equipment.
The term "Electric Wiring Diagrams" refers to diagrams of how a property or building is wired. When a property or building is constructed,the building plans for the property under construction would incorporate a set of Electrical Wiring Diagrams or drawings, as agreed by the Architect and developer or home owner. An Electrical Wiring Diagram is essential for the construction process in that the plans will indicate the position of Lighting Points,Light Switches,Socket Outlet Points and Power Outlet Points for appliances and any other equipment as agreed,to allow installation of conduits and or trunking,light switch and receptacle boxes to accommodate the wiring and switches.
