Going around the existing patio (and the new deck) is a power supply

What is TO&I in this context?

Whoops! T&E I meant :-(


Well the main risks with T&E outside is exposure to sunlight and lack of
mechanical protection. The fact that it is sleeved in something helps
greatly. However it is impossible to say how good or bad it is without
knowing what the arrangements are made at both the head of the cable,
and what is going on in the shed.


I've just cut off and made safe a bit of T+E dangling between the trees,
feeding some gate lights.

I would estimate it to be about 10-15 years old. It wasn't brittle but the
sheath was noticably harder than it should have been. Don't know how much
longer it would be before it became dangerously hardend, but it was well on
its way.

The PVC round conduit on the last leg to the bulkhead fittings shattered
when I touched it with the strimmer cord (hence the urgency in
disconnecting the circuit) - that was very very brittle.

So yes, sunlight does very much affect PVC, from first hand experience.
