Evening all,

Sorry to bother you guys with possibly a very simple question but something I've never been clear on is why the csa of the cpc in twin and earth is smaller.

I've just started my electrical career and my fellow colleagues argued over the reasoning when I asked them!

Any info to help me understand this more would be gratefully appreciated.

Also, does any body run a reduced cpc csa when running circuits in singles?

Cheers!
 
Gotta love stripping T&E.

I use the cpc pull method, and yes, its generally the nearest wall that bears the brunt when it slips/snaps.

Anything 4mm and above gets the stanley.
 
did you know your more likely to cut yourself with a blunt knife than a sharp one , smacked my self in the nose and gave me a nose bleed once lol
 
coas its quicker to pull the CPC. I dont use side cutters, i use the ones above. I pinch the CPC with theflat bits of steel near the handles, so it doesnt slip, or cut the CPC

I was giving my brother a rollicking whilst he was stripping a 2.5mm in an airing cupboard
He wasn't concentrating so I believe I was responsible
Snap, bang, eye,cutters with small piece of cpc sticking out,ripped down his eye
He held his hand to the eye and when he took it away,for a very short moment I saw the damage as what appeared like a half cupfull of water streamed down his face,I mean half a cupfull,thats not exagerating
He lost the eye

The reason for the detail
Always direct the cutters away from you as you strip
A simple message,but vey important

How many of us can say that they havn't been whacked by the cutters stripping cable
 
I use these

They work well on t&e and singles and saves punching yourself in the face.
 
Three broken teeth for me. After 22 years I had got off lightly with nothing more than grazed knuckles then bang and I smack myself in the mouth with me cutters. Mouthful of teeth shards and and a gap where they used to be. Had to be in winter as well so when the cold air hit the now open nerves I nearly hit the ceiling. It only takes a moments laps of concentration. Still got some new ones fitted and haven't done it again.............as yet!
