Wiring diagrams help technicians to find out how a controls are wired to the system. Many people can understand and understand schematics known as label or line diagrams.

    This type of diagram is similar to having a photograph of the parts and wires all connected up. A wiring diagram is a kind of schematic which uses abstract pictorial symbols to demonstrate all the interconnections of components in the system.

    Wiring diagrams comprise a pair of things: symbols that represent the constituents in the circuit, and lines that represent the connections with shod and non-shod. Therefore, from wiring diagrams, you already know the relative location of the constituents and the way they are connected.

    To read a wiring diagram, first you must know what fundamental elements are included in the wiring diagram, and which pictorial symbols are utilized to represent them. The common elements in the wiring diagram are ground, energy, wire and connection, output devices, switches, resistors, logic gate, lights, etc. A line represents a wire. Wires are widely-used to connect the components together. All points down the wire are identical and connected.

    Wires on some places must cross each other, but that will not imply that they can connect. A black dot is employed to suggest the injunction of two lines. Main lines are represented by L1, L2, and so on.

    Usually different colors are used to distinguish the wires. There should be a legend for the wiring diagram to share with you what each color means. Usually circuits exceeding two components have two basic types of connections: series and parallel. A series circuit is a circuit through which components are connected along a single path, hence the current flows through one element of reach the next one.

    In a series circuit, voltages accumulate for many components connected inside circuit, and currents are the same through all components. In a parallel circuit, each device is directly connected to the power source, so each device receives the identical voltage. The current in a very parallel circuit flows along each parallel branch and re-combines once the branches meet again. A good wiring diagram needs to be technically correct and clear to see.

    Take care of every detail. For example, the diagram should show the best direction from the negative and positive terminals of each one component.

Be aware that the power lines are referred to as: L1, L2, L3 respectively however there is no specific order to the power lines, meaning these tittles can be used interchangeably. Connect ground wire to wire terminal.A wiring diagram is a form of schematic which uses abstract pictorial symbols to exhibit each of the interconnections of components inside a system.

    Wiring diagrams are made up of two things: symbols that represent the components in the circuit, and lines that represent the connections with shod and non-shod. Therefore, from wiring diagrams, you know the relative location of the components and just how they are connected. A first look at a circuit diagram could be confusing, but if search for a subway map, look for schematics.

    The purpose is similar: getting from point A to point out B. Literally, a circuit is the path that permits electricity to circulate. This guide will highlight many of the common symbols that you will be sure to see with your future electrical engineering career. Current: Current will be the flow of electricity, or even more specifically, the flow of electrons.

    It is measured in Amperes Ampsand will only flow when a voltage supply is connected. Materials including gold or copper, are classified as conductors, because they easily allow flow of movement low resistance.

    Plastic, wood, and air are samples of insulators, inhibiting the movement of electrons high resistance.

    DC Direct Current. DC can be a continuous flow of current in one direction. DC can flow not only through conductors, but semi-conductors, insulators, or even a vacuum. AC Alternating Current. In AC, the flow of current periodically alternates between two directions, often forming a sine wave. The frequency of AC is measured in Hertz Hzwhich is typically 60 Hz for electricity in residential and business purposes.Single phase power is typically reserved for lower power requirements, however in some cases powering a small motor with single phase input power is practical.

    Single phase motor starters are not commonly available since this is a rare case, and with a little bit of know-how, a 3-phase motor starter can easily be wired for single phase power. Previously, we discussed what a magnetic motor starter is a contactor and an overload relay. The overload relay is designed so the current to the motor is shared between phases, so if you only wire up one phase, then all the motor current goes through one of the contacts on the overload, and you can actually create an overload condition.

    To prevent this, it is important to wire the starter so the current is balanced between the contacts on the overload relay. Here again is our picture of the 3-pole motor starter. The contactor is on top and the overload relay is attached directly to it on bottom. You see 4 terminals because there are 3 poles and an auxiliary contact. As an example, the auxiliary contact can be used for something like turning on a pilot light on the control panel, to indicate the motor is operating.

    We start by bringing in the 2 power leads to L1 and L2 on the contactor. Then we add a jumper wire from L3 on the contactor to T2 on the overload relay. Please note, as this jumper wire will be carrying line power to the motor it is important the wire gage is selected based on the current load going through the contactor. Then you connect the 2 motor leads to T1 and T3.

This site uses cookies: Find out more.Three phase systems are extremely common in industrial and commercial settings. They can also be found in large residential complexes and appliances requiring a large amount of power. Although these systems may seem intimidating at first, a walkthrough on 3 phase wiring for dummies will help clarify the whole situation.

    Different regions may use different voltages, frequencies, and requirements when it comes to electrical power systems. However, they all agree on the fact that three phases are the optimal number to bring the largest amount of power at the lowest number of conductors. It is thus very important to know how to work and be capable of troubleshooting different systems which require these connections.

    When we talk about three phases, we are always inferring that we are working with Alternating Current AC. The electrical term AC simply means that the current will alternate the direction of the flow. The frequency of the current will determine the number of times the flow will be alternated per second. AC is found in house outlets and used for most appliances in your home. Any appliance will have a number of parameters related to its electrical properties.

    These parameters are Voltage, Current and Power. Voltage can be taught of as the available pressure of electricity. A typical home will provide or volts depending on where you live.

    Current is measured in amps and is the rate of flow of electrons within a conductor. The amount of current required will depend on the appliance. Depending on the source, this system may also have a neutral wire for returning current back to the transformer. The most common use of three-phase power is for motors. It provides a unique feature which is a rotating field in order to rotate the motor without the need of a starter circuit. This is accomplished due to the fact that each one of the three phases has a different offset.

    In simple terms, the current is being alternated during a different time. As the motor windings receive current, they create a magnetic field which propels them toward the next stator winding. As the current alternates, the motor is propelled further and further.

    In practical terms, a three-phase motor will need to be wired in one of the configurations described on its faceplate. The first step is to figure out the voltage of your phases. In the United States, for low voltage motors below vyou can expect either v or v. That being said, there is a wide range of different motors and what you have on hand can be completely different. Make sure that the voltage you will be supplying to your motor matches the specifications on the faceplate.

    Turn off the power coming into the motor and open the cover which encloses the terminals.

    Here, you will either find numbered wires with wire nuts or a set of screw terminals. The type of connectors will depend on the manufacturer and size of the motor. Locate the wiring diagram for your motor on the faceplate or inside of the cover you have removed. Typically, you will have two distinct diagrams. One will be for low voltage and another for high voltage connections.
