Almost certainly the answer will be found in BS1363 Part 1, Specification for rewirable and non-rewirable 13A fused plugs. (I assume you are referring to UK plugs, as I don't know of any other plug with a fuse).
My copy of BS1363 is rather old, but there is a table which shows a 3A (5A) fuse used with 0.5 sq mm cord, and 13A fuses used with 0.75, 1.0, 1.25 and 1.5 sq mm cord. A note states "the figure in brackets indicates the fuse rating where a non-rewirable plug/cord assembly is used with certain types of equipment where the use of a 5A fuse-link is necessary because of the high instantaneous input current". So the answer to your question is yes, BS1363 specifies a 13A fuse for 0.75 sq mm cords.

Thanks in advance. Kind regards, Chris. ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
