Singles in a partition

[estebandonde]

Hi Guys,
I'm a bit rusty but I've just seen single cables installed in a stud partition used for sockets etc. I've never seen this done before but can someone confirm if this is ok?

I seem to remember that they should be double insulated (T&E) or single + mechainical such as conduit/trunking etc

or does the partition act as a mechainical protection???

cheers

No way is that OK.

You are correct; it needs to be T+E or conduit.

or sheathed singles.

No not aloud twin and earth or if you use singles copex or flexi hose

Cheers guys, do you know if this is just bad practice or against the regs??

If is it against the regs does anyone know which one??

Been home for lunch and found my regs book, 521.10.1 states that "Non-sheathed cables for fixed wiring shall be enclosed in conduit, ducting or trunking. This requirement does not apply to a protective conductor complying with section 543

So no singles allowed in a stud partition unles in conduit, flexible conduit etc.

cheers all

or sheathed singles.

Wonder if they are sheathed singles...

Just an FYI, T&E are not double-insulated but insulated and sheathed. It is the sheath which forms the mechanical protection (as you pointed out), so without it the cable must be protected by conduit or trunking.

and if the studding is metal, RCD irrespective of depth.
