For example: L1 and L2 indicate that the motor voltage may be 240 volts. The L symbol designation refers to the Line, or the incoming circuit wires that provide the power for the motor. Some motors will require a dedicated circuit and specific amperage rating.

Therefore, consult the installation instructions that came with the motor to identify the circuit voltage that will be compatible with the motor, and what the circuit requirements will be. The voltage is also different in other countries. There are also a variety of voltage ranges that motors are made for, and the voltage is not the same for all motors. There are many types of electric motors, and many wire connections, and some are very specific to the type of motor and its intended application. This electrical wiring project is about wiring a new 240volt motor. North Carolina Electrical Contractor License, Building Permits and Electrical Codes Basic Wiring for a 240 Volt Motor Locate Electricians or Electrical Contractors in North Carolina Resources to help you do electrical wiring in your area: A permit and inspections may also be required.

Skill Level: Intermediate to Advanced – Best performed by a Licensed Electrical Contractor, or Certified Electrician.Įlectrical Tools Required: Basic Electricians Pouch Hand Tools, Voltage Tester, and appropriate Safety Gear.Įstimated Time: Depends on the personal level experience, ability to work with tools, install electrical circuit wiring, and the available access to the project area.Įlectrical Safety: Identify the electrical power source to the 240 Volt Motor, turn it OFF and Tag with a Note before working with the electrical wiring.Įlectrical Wiring Parts and Materials: Electrical parts and materials for the 240 Volt Motor should be approved for the specific project and compliant with local and national electrical codes.Įlectrical Codes and Inspections: Installing or changing home electrical wiring should be done according to local and national electrical codes as adopted in Kings Mountain, North Carolina. Thanks for your electrical wiring question Marlon. This electrical wiring question came from Marlon, a Homeowner in Kings Mountain, North Carolina. There are wires marker like T2 T3 T4 T5 and so on, which I assume you have to twist together with certain wires. The motor can be hooked up to 110 or 240, and also supposedly reversed. For example what is L1 and L2? I am assume that is the power legs.

I am trying to run power to a 240volt electrical motor I bought but I do not know what the abbreviations mean and how to read the diagram that came with the new motor.

My electrical wiring project involves wiring a 240volt motor. Older homes may have 150-amp, 100-amp or lower service capacity.Electrical Question: What do the L1 L2 and T1 T2 wiring diagram abbreviations mean when wiring an electrical motor? This is standard for new home construction. For example, a home with 200-amp service will have a disconnect breaker rated for 200 amps. The breaker is rated for maximum current, measured in amps. These wires connect to the disconnect breaker installed within the disconnect box. The total voltage, when measured between them, is around 240 volts. These phases are normally called "A" and "B" phases. The hot wires each carry 120 volts and are different phases. There are two hot wires and a neutral wire. The side of the meter that receives incoming power from the utility service lines is called the "line" side. The electrical wiring to the disconnect is fed from the "load" side, or outgoing side, of the electric meter. It is best for disconnect switches to be installed by a licensed electrician or someone highly trained in residential electrical systems. The disconnect switch does not shut off the power in the feeders lines or at the switch connections. The feeders and the terminals they connect to on the disconnect switch are live at all times unless the utility has shut off the power to your service.
