Twin and earth external use.

[Derrick]

Can twin and earth be used in an external twin brick cavity wall? In no way open to the elements.

Can you meet the manufacturers requirements for support i.e clips?

Find that a slightly unusual requirement. Cables run in the cavity would normally be laying at the bottom. Does that not count as "support"?

Think that comment was before all the details were evident and assuming it was a vertical drop.

Even if it was a vertical run, the amount of cables I’ve seen hanging down cavities and never a problem with them.

I wouldn’t do it, but is it really a big issue if there is little other choice than running surface, which customer won’t accept?

T/E will be OK.

Before the advent of fire clips any drops in trunking would be unsupported.

Traditionally a loose hanging cable in a cavity was deemed to be in less danger from damage than a fixed one as it could move in the event something touching it (a, drill bit)

I run t&e in cavity when possible but always use flexible conduit as an extra protection.

Got it. A simple solution.
thanks again.
I do have one more question to ask once I have figured the best way to present it.
hope you don’t mind.
