A few more questions on this please Tim:
- Can I remove USB sockets with 32amp junction boxes for the purposes of the IR test?
- Do FCU's that are on the ring and not a spur need to be removed? The neon is on load and can be switched off
- If we have continuity as part of earlier tests, when doing the IR test for L and E (or the other conductors), does it matter which leg of the ring you use the L and E from? I assume not but was mindful of the other end of the leg hanging mid air at this point:

- If there are failures, we can use the halving method and I can gradually increase the working leg of the ring to see where the failure appears. At this point, I could either replace the cable or convert the ring into two radials powered by a 20amp breaker. Is that a valid approach?
