In this video I show how to wire a fused spur (FCU) safely and explain what it is used for in UK electrical installations.
A fused spur provides fused protection for appliances such as boilers, extractor fans, and outdoor equipment by limiting the current through the appliance. I explain the terminals, correct cable connections, and the importance of using the correct fuse rating for the appliance.
⚠️ Always isolate the power before working on electrical circuits. If you are unsure or not competent to carry out electrical work, consult a qualified electrician.
