3 phase electric motor starter wiring diagram – What is a Wiring Diagram? A wiring diagram is a straightforward visual representation in the physical connections and physical layout associated with an electrical system or circuit. It shows how a electrical wires are interconnected and can also show where fixtures and components may be coupled to the system.
When and How to Use a Wiring Diagram
Use wiring diagrams to assist in building or manufacturing the circuit or computer. They are also a good choice for making repairs. DIY enthusiasts use wiring diagrams but they’re also common in home building and auto repair.For example, a home builder would want to read the geographic location of electrical outlets and light fixtures using a wiring diagram in order to avoid costly mistakes and building code violations.

Essential Tips for Safe Electrical Repairs
Repairing electrical wiring, more than some other household project is focused on safety. Install an outlet properly and it’s really as safe as they can be; set it up improperly and potentially deadly. That’s why there are many rules surrounding electrical wiring and installations. The rules may be complicated, definitely, and sometimes confusing, even for master electricians, but there are basic concepts and practices that affect virtually every electrical wiring project, specially the kind that DIYers are capable of tackle.
Here’s a look at five of the biggest rules that will aid help you stay safe when making electrical repairs.
1. Test for Power
The best way to prevent electrical shock would be to ALWAYS test wires and devices for power before implementing them or near them. Simply shutting off of the power is unappealing enough.
Further, it is not uncommon for circuit breaker boxes to become mislabeled, specifically electrical service may be extended or adapted over the years. The circuit breaker label may well not accurately describe what are the circuit breaker actually controls.
Always test for power before taking care of any circuit wires.
2. Check Amperage Ratings
All electrical wiring and devices have an amperage, or amp, rating. This is the maximum quantity of electrical current they’re able to safely carry. Most standard household circuits are rated for 15 amps or 20 amps, while large-appliance circuits (for example for electric dryers and ranges) could be rated for 30, 40, 50 amps, and up.
When installing or replacing wiring or devices, all the parts you use should have the appropriate amperage rating for that circuit. For example, a 20-amp circuit will need to have 12-gauge wiring, that is rated for 20 amps. If you install 14-gauge, 15-amp wiring on that circuit, you create a fire hazard because the 20-amp circuit breaker protecting that circuit may well not shut down before the 15-amp wiring overheats.
When replacing a switch, light fixture, or outlet receptacle, ensure to not purchase a device which is rated for more amperage compared to circuit carries. This is especially important when replacing receptacles. A receptacle rated for 20-amps has a unique prong shape where one of the vertical slots has a T shape. This shape allows 20-amp appliances, which have a matching T-shaped prong, to be inserted. Installing a real receptacle over a 15-amp circuit assists you to possibly overload the circuit in case you plug this type of 20-amp appliance with it.
Note, however, that there’s no danger to installing 15-amp receptacles in 20-amp circuits as it is perfectly fine each time a plug-in device draws less power as opposed to circuit amperage. In fact, it is quite normal for 20-amp general-use circuits being wired with 15-amp receptacles.
3. Make Tight Wiring Connections
Electricity travels along conductors, such as wires and the metal contacts of outlets and sockets. Tight connections between conductors create smooth transitions from conductor to another. But loose connections behave like speed bumps, restricting the flow and creating friction and heat. Very loose connections can bring about arcing, through which electricity jumps with the air derived from one of conductor to a new, creating tremendous heat.
Prevent fire hazards start by making sure all wiring connections are tight and have full contact from the conductors being joined. When splicing wires together, use approved wire connectors (“wire nuts”).
Outlet receptacles and switches will often be manufactured with push-fit wire connection slots around the back, with the traditional screw-terminal connections around the sides in the device. These push-fit connections are notorious for loosening or failing, so professional electricians almost unanimously avoid them and only making very tight and secure screw terminal connections.
4. Respect Grounding and Polarization
Grounding and polarization are crucial for your safety of contemporary electrical systems. Grounding provides a safe path for stray electrical current caused by a fault and other overuse injury in a circuit. Polarization means that electrical current travels in the source along “hot” wires and returns towards the source along neutral wires.
Always follow manufacturer’s wiring diagrams when replacing a fixture, and understand—and use—your home’s grounding system to make certain grounding and polarization remain intact.
There are a variety of ways to test for grounding and polarization. A simple plug-in circuit analyzer tool, readily available for some amount of money, can make it possible to routinely check outlets to ensure they may be wired correctly.
5. Box It, Clamp It
The National Electrical Code (NEC) necessitates that all wiring connections be generated in the appropriate enclosure. In most cases, this implies a box. Enclosures not simply protect the connections—and protect people from accidental contact with those connections—they also provide opportinity for securing conductors (like electrical cables) and devices.
The rule here is simple: avoid being lazy. If you need to create a wiring splice, purchase a junction box and secure the cables on the box with cable clamps. Never leave a splice or any other connection exposed or unsecured.
