PAT Test - Flex Replacement

For flexes to be protected by the fuse in a BS1363 plug there is no limit to their length, providing their cross-sectional areas are below:

3A 0.5mm2
13A 1.25mm2

Other considerations such as voltage drop may limit flex lengths. Smaller csa's than those given are acceptable if flex lengths are restricted. However, for replacement purposes the above simplified guidance is appropriate.

A table showing Flex Resistances and Maximum Current Carrying Capacity can be found here

The maximum lengths recommended for extension leads are not applicable to appliance flexes or cord sets.
