BT Overhead Telephone Cable.

Leg A is 0V. Leg B is -48V. The positive terminal of the battery, leg A, is tied to earth. This prevents leg B from losing material via electrolysis.
Thanks. As I've just written, the statement makes sense when one specifies (as you now do) what the polarity is being measured relative to.

Kind Regards, John

Always earth. Trailing a big floating cable around the place doesn't work as well as one may hope.
 
Thanks everyone.

The fact is, when I un-clip the old guttering, I didn't want my hand to bounce back and hit the wire.

I DON'T want to remove his active BT Line, just didn't want to touch it!

My neighbours guttering should of been on their other side so no, i'm not working around it, just replacing my side as 5 roofs of water going into that 1 downpipe is causing my walls to go black with damp because of the huge overflow!

Thanks once again for everyones reply

No, because you might get some drips of water running down your sleeve.

It's insulated. Nothing to worry about from an electrical point of view.
