Just out of curiosity, does anyone know the tensile strength of a 12 awg solid conductor?
I have a UBS of 336.9 lbs for hard drawn #12 copper.
add:
261.6 lbs for medium hard drawn
197.5 lbs for soft or annealed
Ultimate Breaking Strength. It is what we use to determing maximum pulling tensions. Maybe I misunderstood what the OP was after.according to this site www.southwire.com
0.008 lbs per cmil
so, a 12awg copper has 6530 cmil
6530 x .008 = 52.24 lbs
but is way different than what MIVEY has.
Mivey,
what is UBS?
From my pulling calculator. Not that the allowable pulling tension is lower than the UBS (we use 60% for the smaller wire).Mivey,
I like to know where you got the UBS info? Thanks
this is good info.
My values were the breaking strength. The values in the southwire bulletin:according to this site www.southwire.com
0.008 lbs per cmil
so, a 12awg copper has 6530 cmil
6530 x .008 = 52.24 lbs
but is way different than what MIVEY has.
Mivey,

MIVEY,
Thanks for your info.
I am still trying to understand the difference between the two:
I will read through my American Electricians' handbook.
