The "Allelectrics 13A Switched Fused Spur" is an electrical accessory used to provide a fused connection point for an appliance or circuit. Here’s a detailed breakdown of its features and purposes:

Allelectrics: Likely the brand or supplier name.
13A: Refers to the current rating of the fused spur, which is 13 amperes. This is a standard rating for many household appliances and circuits.
Switched: Indicates that the fused spur includes a switch, allowing the connected appliance or circuit to be turned on and off.
Fused Spur: A fused connection unit that provides protection to an electrical circuit. It includes a fuse, which can prevent overcurrent by breaking the circuit if the current exceeds a safe level.

Purpose and Use:

• Safety: Provides overcurrent protection for connected appliances or circuits. The fuse prevents potential damage or fire by breaking the circuit if the current exceeds the rated 13A.
• Control: The switch allows users to control the power supply to the connected appliance or circuit without having to unplug it.
• Isolation: Useful for isolating an appliance or part of a circuit for maintenance or in case of emergency.

Applications:

• Fixed Appliances: Commonly used for fixed appliances that do not have their own fuse, such as electric heaters, water heaters, extractor fans, and other high-power appliances.
• Spur Circuits: Used in spur circuits to provide an additional fused connection point from a main ring circuit.
• Residential and Commercial Buildings: Installed in a variety of settings to provide safe and controlled power to specific appliances or parts of an electrical system.

Installation:

• Wall Mounting: Typically mounted on a wall, the fused spur is connected to the electrical supply and then to the appliance or circuit it is intended to protect.
• Fuse Replacement: The fuse can be easily replaced if it blows, ensuring continued protection and functionality.

Overall, the Allelectrics 13A Switched Fused Spur is an essential component for enhancing the safety and control of electrical installations, providing both overcurrent protection and the ability to switch connected appliances or circuits on and off.
