The terminal strips and turret boards are a unique type of electrical connection system designed for applications that require more flexibility than typical terminals, junction boxes, and other rigid connection systems can provide. These units are often used in applications that require high-voltage, high-current, and/or high-speed connections. The two main types of electrical connections used with terminal strips and turret boards are spade lugs and ring terminals.

A spade lug is a metal strip with two wire-insulated ends that can be put through a hole in the center of a terminal block. The spade lug can be fastened in place using a screw or nut and connected to a wire. The terminal block then helps provide a secure and reliable connection between the wire and the terminal board. Ring terminals are similar to spade lugs, but instead of being held in place with a screw or nut, they are affixed to the terminal board with a metal ring.

Terminal strips and turret boards are capable of handling a wide variety of current ratings, voltages, and frequencies. The current ratings of these units are based on the maximum amount of current that the device can supply or support without being damaged. The voltage ratings are typically based on the total wattage that a terminal strip or turret board can handle, and the frequency ratings are based on the speed at which the current can be transferred from the device to the connected wire.

Terminal strips and turret boards have two primary applications, industrial and consumer. In an industrial setting, terminal strips and turret boards are used to facilitate the connection of multiple components in a machine or system. This type of connection helps maintain safe and reliable operation of various processes by allowing rapid replacement of components when needed and providing electrical isolation between adjacent components in the system. In consumer applications, terminal strips and turret boards are used to connect appliances or other electronic devices to a wall outlet.

When using a terminal block or turret board, the specific working principles depend on the type and purpose of the device. In general terms, a terminal strip or turret board contains terminals that make contact with the necessary wires when the device is connected. The terminals can be designed to accept multiple types of connections, including those that use solderless terminals, blade connectors, spring clip connections, and crimp ties. Once all connections are completed, an internal switch is triggered to electrically isolate the connected components from each other, creating an electrical circuit.

Terminal strips and turret boards provide fast and convenient connection of components that require high-voltage, high-current, and/or high-speed connections. They offer flexibility and safety that can’t be achieved with other connection methods, making them a key component in many industrial and consumer applications. Terminal strips and turret boards are a great addition to any application that requires reliable and convenient access to power.
