Current Carrying Conductors

[jazer]

Please see the attachment. Would this raceway have 3 or 6 CCC's?

Six.

Mark

if blue is white, 4 to 6.
if blue is blue, 6
if bottom box contains two s3, 4
if blue is white, and bottom bx contains s4, 2

Six, but if the raceway is 24" or less then it wouldn't matter.

Might not matter even if it is longer than 24", if you can apply the Exception to 310.15(A)(2).

Still the OP is asking how many conductors-- 6 current carrying conductors -- the derate is dependant upon other factors

Sorry....Here is all of the info:

Raceway longer than 24"
3 phase 208, no nuetral
#10 THHN conductors

310.15(B)(16) 2014 code says conductor good for 40 amps.
6 CCC's derate to 80%
conductors now good for 32 amps, still fusable at 30 amps.

Any comments??? And thanks for the help.
