[QUOTE="SteveT, post: 206671, member: 11775"] IMO - A fan being a fixed item will draw a fixed amount of current and wont overload the cable - therefore no need to fuse down in theory as the only time it will pull more than Ib is in fault i.e. short which will draw zillions of amps for a very short time and trip the 6A MCB, not allowing the cable to overheat. With all fixed equipment you can select cable size with Ib as the defining criteria (Other factors grouping etc may have to bre taken into account) [/QUOTE]
