Fused spurs, also known as fused connection units (FCUs), are essential electrical devices used in wiring installations to ensure a safe and controlled connection between the main electricity supply and fixed electrical appliances or equipment. Widely used in Malaysia, the UK, as well as other countries that follow similar wiring regulations, these units incorporate a built-in fuse that offers critical overcurrent protection. This safeguards both the connected appliance and the wiring from damage due to electrical faults or overloads.
RS Malaysia offers a wide range of fused connection solutions, from unswitched fused connection units to single switched fused spurs, ensuring reliable and compliant connections for your projects.
Fused spurs offer several key advantages that make them indispensable in electrical installations:
There are generally two main types of fused spurs or fused connection units: switched fused spurs and unswitched fused spurs.
These units incorporate an on/off switch, allowing you to control the power supply to the connected device directly at the spur. They are commonly used in applications where you need the ability to isolate the device without affecting other electrical circuits. The switch typically has a clear "on" and "off" position, making it easy to determine the power status.
As the name suggests, unswitched fused connection units do not have an on/off switch. They provide a fused connection point for appliances or devices but do not include a switch for direct control of the power supply. Unswitched fused spurs are typically used when a separate switch is already present in the electrical installation or when control is not required at the spur itself.
A fused spur is a fixed electrical connection with a built-in fuse, designed to safely power appliances that do not require a full socket outlet, such as electric heaters, boilers, or integrated kitchen appliances. It works by protecting the connected device with a dedicated fuse, which acts as a sacrificial component. Should an excessive current flow through the circuit, the fuse wire within the connection unit melts, breaking the circuit and preventing damage to the appliance or potential fire hazards. This ensures a localised safety mechanism for permanently wired appliances.
The choice between fused spurs with a switch and those without depends entirely on the application's specific requirements.
Switched fused spurs offer the distinct advantage of providing immediate and visible isolation for the connected appliance. This direct local control is invaluable for devices requiring frequent power cycling, servicing, or emergency shutdown such as appliances like washing machines, dishwashers, or kitchen hobs, where an accessible on/off function at the point of use enhances safety during operation or maintenance.
Conversely, unswitched fused connection units are ideal for equipment that should remain constantly powered for critical functions, such as security alarm systems, central heating boilers, refrigeration units, or fire detection systems. In such scenarios, the absence of a local switch minimises the risk of accidental power disruption, safeguarding essential operations and preventing unintended outages.
Installing a fused spur requires careful adherence to electrical safety regulations and should be performed by a qualified electrician to ensure compliance and safety. Here are the basic steps involved:
