Fused connection units are shipped by the manufacturer with a 13A fuse, this can be changed for a lower rating if the situation warrants it. a>

Halfords Autocentres Ltd is authorised and regulated by the Financial Conduct Authority (FRN 755309) and acts as a credit intermediary and not a lender, offering credit products provided by a limited number of finance providers, including Payment Assist. The new, simpler A-G energy rating scale is stricter and designed so that very few products are initially expected to achieve the top “A” rating. Overcurrent can be caused by short circuits (in which current travels down the wrong path), configuration faults, electrical arcs, and similar issues.

Slow Acting fuses include a delay mechanism that allows short, lower power electrical surges to pass through the circuit without the fuse blowing. One of the first questions to ask when planning your installation is what size wire to use, which will later determine what fuse to use.The rating of fuse fitted within a plug depends on the power rating of the device to which it is attached. It is only about 40w (halogen I think) but I was thinking the wire out to it might be damaged or faulty in some way (it's got a light sensor and stuff on it which has been playing up) and causing surges. If you have a training lead such as a 4-gang socket or more extension lead, this will only be rated to maximum of 13 amp.
