However, in European countries, the color codes differ significantly. Many professionals emphasize the importance of following local codes to ensure safety and compliance.

Now, let’s examine each wire color in detail.

Black Wire:
The black wire functions as a hot wire. It carries electrical power from the source to the load, such as lights or outlets. Using black wires with proper insulation is crucial to prevent electrical shocks. According to the NEC, all hot wires must be treated with caution during installations.
Red Wire:
The red wire serves as a secondary hot wire. It is often used in circuits that require two hot wires or in three-way switch setups. Red wires can also be used for interconnecting smoke detectors in larger homes. It’s important to ensure that the circuit is properly marked to avoid confusion in future adjustments.
White Wire:
The white wire acts as the neutral wire. It returns the current from the load back to the electrical panel. Connecting the white wire incorrectly can lead to shorts and electrical hazards. The NEC states that neutral wires must be connected to the ground at the panel to ensure safety.
Green or Bare Wire:
The green or bare wire serves as the ground wire. It provides a safe path for electrical current during faults. Ground wires help protect users from shocks by ensuring that excess electricity is redirected away from circuits and appliances. The grounding system must comply with the NEC to ensure effective safety measures are in place.

What Functions Do Each of the Wires Control?

Wiring a 4 wire China AC motor involves understanding the functions of each wire. Each wire typically serves a distinct role in the motor’s operation.
