Ceiling Fan Wiring

Ceiling fan wiring is meant to provide power connection to the fan. If done with proper care it's safe and easy. The ceiling fan wiring is divided into two parts:

1. Wiring from fan terminal box (if provided) to internal motor or circuitry and 2. Wiring from switch box or switch unit up to the ceiling fan. The first part of ceiling fan wiring falls under the fan maker's scope and the rest is taken care of by the user. This part may be put inside a concealed unit called concealed wiring. The wire from the switch box comes through this concealed unit up to the fan terminal box. There are usually three types of ceiling Fan wires: 1. Power wire, or phase wire, or hot wire. 2. Neutral and 3. The ground or earth.

Color Code: At the time of ceiling fan wiring, a defined Color code helps to identify the types of wires. For the hot wire or the power wire, different color combination such as black or red are used depending upon the industry standard, whereas generally white color is used for ground wires.

Gauge: For the purpose of ceiling fan wiring, proper gauge of wire is to be used. Though gauge usually varies with the current rating of the equipment, no. 12 or no. 14 is to be used for such wiring. No. 14 is the smallest permitted ceiling fan wiring under most codes.

Proper copper multistranded wires are used for ceiling fan wiring. The ends of the wire must be dressed properly and crimped with a crimping tool. These steps are followed in order to rule out connectivity problems. However, Ceiling fan wiring varies with the instructions of the manual provided by different brands.

Safety: *Before giving final connection, power in the loop should be switched off either tripping the MCB or circuit breaker. A neon tester can be used to check if the power is off. In case of any doubt, remove the main fuse or trip the main breaker. However, removing the main fuse or tripping the main breaker will shut off the power to the entire house. *Wherever two wires are joined externally, proper insulation with insulation tape is to be put for safety. *Continuity of ceiling fan wiring is to be checked with a proper continuity tester device before giving power. Proper connectivity of these wires with terminal box and switches also to be checked.

Electrical Engineering Technology

In order to succeed in their jobs, electrical engineers have to be familiar with a variety of electrical engineering technology. To deal with various aspects of electrical engineering technology, electrical engineers must become familiar with various theories of communications, electricity, and electronics. Electrical engineers can use electrical engineering technology to help them develop new systems, test systems, and make older systems more effective and efficient. Electrical engineers learn the drafting, designing, and technical skills that they will need to put their ideas as an electrical engineer into action.

One type of electrical engineering technology that electrical engineers must be very familiar with is the technology of circuits and how they work. In its simplest form, an electrical circuit is a connection of electrical elements that is in a closed loop to allow the current to pass through continuously. Electrical engineers learn how to predict where the current is in the circuit and the voltage that is in the circuit, as well. In today?s world, it is much easier to design circuits than ever before due to newer electrical engineering technology that has software called circuit simulation software, to design the circuits safely and effectively.

Digital and analog electronics is another form of electrical engineering technology that engineers must be well acquainted with to perform their jobs. Both digital and analog electronics are used in computers and phones, however, digital electronics are becoming more widely used as analog electronics is becoming more and more outdated. This form of electrical engineering technology requires that engineers understand Boolean algebra, digital circuits, and how logic gates work. Even those that deal with digital electronics must also understand the electrical engineering technology of analog electronics as well. Digital electronics are usually built with various analog components, so understanding how analog electronics work is essential.

Another type of electrical engineering technology that electrical engineers must be familiar with is opto-electronics. This technology deals with how light interacts with devices that are electric. Various forms of light that may be used to interact with these devices include X-rays, infrared, gamma rays, and ultraviolet rays.

Electronic engineers also have to be familiar with the electrical engineering technology that deals with control systems as well. Control systems are used to control electrical devices as well as regulate and command them. Engineers must know the differences between sequential controls and linear controls and how to properly and effectively use these control systems. This type of electrical engineering technology can be used in a variety of ways from controlling your computer to controlling aspects of a space shuttle.

If electrical engineers are going to be effective in their jobs, they must understand electrical engineering technology and how it works. There are many different technologies that they must use together in their work each day. Because of the knowledge required, becoming an electrical engineer is not for the faint of heart. It takes years of study and work to be able to implement various forms of electrical engineering technology in order to successfully complete electrical engineering jobs.
