Small Split in Twin and Eath Outer Sheath

I guess furry-tailed mammal's is a possible reason. With regard to the repair. I would rather be safe than sorry. Would adding two single 13a sockets to extend the ring main be a valid fix? as I said I could do with some extra sockets.

I guess furry-tailed mammal's is a possible reason.

It is, and in my experience, places where cables go through holes are very often nibbled - I guess in an attempt to enlarge the available space enough to squeeze through!

Any approach which resulted in that damaged section of cable being removed would obviously solve that particular problem. Perhaps the bigger issue, if one is contemplating the possibility that you're seeing the work of rodents, is that they rarely nibble just one cable - which obviously opens up a whole new can of worms (and one which, as I've illustrated, cannot be confidently addressed simply by 'testing').

Many Thanks , so repair the problem I will insert two single 13a socket into the ring main, removing the damaged cable. As for the rodents, that will need some more thought. Anyone got a really hungery cat ?

Now having seen pictures if it were my house I would test the cable to ensure earth not damaged then seal with some silicon sealant. Not ideal I would admit but as long as the testing proved the cable is OK that would be limit to my repair.

However if I had the same to do as a work related repair then I would have to play safe and likely replace the cable.

It is down to risk assessment and watch my back. At home not worried about some one else criticising my repair. Also I have all the readings dating back years so any degrade easy to spot. So easy to plug in my loop impedance tester and compare results. One good reason for having a EICR every 10 years.

Agree with Ericmark.

Though it may or may not be a serious bit of damage, I would rather it not be there.

To me, it looks like it may have been damaged with some kind of saw.

Before I head out to tcl can I just confirm that my proposed fix will work and is permissible. I have cut two new strips of cable (about a 1m long) the ring main in question powers 2 13a double sockets (shortly below the damaged area). Both parts of the ring are damaged. I plan to cut the cable above the damage then add 2 single sockets into the ring main, replacing the cable below the damaged area.

That sounds OK clearly you will need to test the ring is a ring for all functions neutral, line and earth.

... Both parts of the ring are damaged. ...

What do you mean by this? Have you found a second damaged cable?

Yes, there are three cables pushed through a wooden baton. 2 * 2.5mm cables that form the ring main, and 1 * 1.5mm cable to power an alarm (which is not fitted) this alarm is on it's circuit. Both the ring main cables have similar damage on the outer sheath.

Thanks I plan to have the work checked over / tested when complete. What would the charge for this typically be?

Thanks for clarifying. I think that probably increases the likelihood that something other than just 'pulling through the hole' has resulted in the damage.

As others have said, whilst the solution you propose would be satisfactory if it is a ring circuit, you need to be absolutely sure that the cables in question are part of a ring before you do it.
