I have some 16A c-form cable. Some is 2.5 other is 1.5. Its in lengths of 5m, 10m, 20m and 30m. As this is not clipped direct and goes out on hire i guess i need to replace the 1.5 with 2.5 as its just not safe for that situation? Also what would be a suitable Earth Bond limit for a PAT test on the 2.5 cable? A calculator online says that it should be the following: 5m 0.14 10m 0.18 20m 0.26 30m 0.34 Some of the 20m 2.5 cables are failing as they read at 0.28 is there any lee way on this? e.g can i increase the pass limit to 0.29 and still be safe? All the 1.5 cables i test with these settings fail.
