What is an earth braid on a cable - how does it wire in?

I have a cable with an earth braid, rather than an earth wire.

How does this connect to a standard spur?

Is the braid simply sheathed and connected to a standard earth point?

Thanks

Thanks for the quick reply.

I have simply never come across braided wires and only conclusion I could come to was to strip enough outer and sheath the earth. But wanted to check this was fine.

Is there a reason for using braided wire over seperate earth wire?
 
What is this cable being used for and where did it come from ?

Braided cable in not commonly used for domestic electrical equipment. It is used in industrial.

I am a bit concerned as I have found twin micro-phone cable used to wire mains to several items in a house. "It works so what is wrong" was the comment when I pointed out the cable was not designed to work at 240 volts.

Hi bernardgreen

The cable is for an underfloor heating kit being installed under a tiled floor.

I too would be very concerned if someone was wiring with twin micro-phone cable on 240v.
 
The braid on under floor heating must be earthed. It makes sure that you are protected should there be a fault.
 
Thanks taylortwocities

I understand it must be earthed, I just wanted to check whether there was a special method/connector for braided earth or whether to simply strip, sheath and connect.

From these posts my understanding is to strip, sheath and connect to the earth.
 
Yes, that the way. You'll find that the element cable ends (with braid) will end up at the heating controller. The terminals are usually quite small so its best to join then together with the earths from the supply in a terminal block and then run a small piece if wire to the eath terminal on the controller (there usually is one).
 
Thanks taylortwocities.

The heating controller does not have an earth point, I was going to run to the earth block in the single pattress box.

Still interested, why use braided rather than a seperate cable - I can see no obvious benefit.
 
Thanks for your help everyone - have found the reason for the braid:

"Referring to section 601-09-04 of the 2001 edition IEE wiring regulations heating cables installed in ‘wet areas such as shower and bathrooms must incorporate an integral earth braid (type PSV)'."
