Basic insulation _______

[Louicardist23]

Is double insulation cable necessary such as twin and earth if under automatic disconnection of supply it states that basic protection can be achieved by basic insulation only.
Thanks

strange question.T/E is not double insulation.it is insulated and sheathed.

I think you are referring to double or reinforced insulation which is a means of both basic and fault protection. T/E cable is not classed as double or reinforced insulation.

No such Animal as Double insulated cable Mate, it's classed as insulated with a mechanical protective sheath.

The reason why T&E is not deemed as double insulated, is because there is only one layer of insulation between the CPC and anything else.
Insulated and sheathed singles are deemed as being double insulated.

It does not carry the Double insulated icon, ergo it's not double insulated.

Wiring is not required to carry the Double insulated icon.

Ah Thanks, that clears a few things up, I should have just asked is twin and earth classed as double insulated.

Ok just to get this straight, Are you saying then that theoretically an installation could be wiring in insulated sheathed singles (double insulated) without the use of ADOS?
Thanks again

No.

Take photos to share with us as you do it and also share the cost of the install. Nice one.

singles are insulated and sheathed not double insulated, but even if they were you would need some means of protection from electric shock through faults at the terminations/accessories, not just the wiring itself. you would also need to run a CPC to all points in or with the wiring system as well.

I know but it is not double insulated

Yes I agree but anything being deemed as double insulated should carry said logo.
