For which applications are wire nuts typically used?

Wire nuts are commonly used for electrical connections in various appliances due to their versatility and effectiveness in joining multiple wires together. They are designed to securely twist onto the stripped ends of wires, providing a reliable and insulated connection. This is particularly important in appliance wiring, where connections need to be safe and capable of handling the electrical load without risk of short circuiting or accidental disconnection.

The other applications mentioned may require specific types of connections that are not provided by wire nuts. Heavy-duty motors, for instance, often require more robust connections that can handle higher currents and may use terminal blocks or specialized connectors. Low-voltage devices typically do not require wire nuts as they often use unique connectors or terminals designed specifically for low-voltage circuits. In outdoor lighting installations, while wire nuts could be used, more moisture-resistant connection methods such as sealed connectors are usually preferred to prevent corrosion and ensure longevity in outdoor environments.
