Hi,
I hate to say it but putting 50 wires in a conduit is not a good way to go..what it cost to do it right is not what is important..
sure the NEC will give you ways to pull that off in a safe way...all i am saying is that there is a better way...most of the jobs i work are already planned by the engineers...i have NEVER in my 27+ years run across a drawing that showed 50 conductors in a single raceway! i aint saying that it cant be done i am just talking best practice i guess..most of the jobs i am working MONEY IS NO OBJECT.
I am certainly not clear as to the intentions of derating and that is why I started the thread..I am just thinking outside the box to see if there is more behind the rules..
there is also such a thing as pull-ratio...I mean that 4 wires are easier to pull than 3 etc etc..this is part of conduit fill and not derating correct?
i certainly have seen conduits full of current carrying conductors and understand that the derating is for limiting the amount of heat that the conductor is designed for...
it just strikes me as a way to correct a mistake...besides the temp adjustment..
i am just trying to further my knowledge on the subject and to take a step back and look at the issue in a different perspective..
i guess there is no mystery to derating and it is very cut and dried to some.
anywho...thanks for the discussion and putting up with my nonsense!
there is always stuff to learn and to me anyone who is seeking knowledge is ok in my book, its the people who wont change or that see things with blinders on that irk me..
i cant wait unitl we discover how to transmit energy through the air and get rid of all these wires!
heres to the future!
thanks agian to all the good and bad replies!
-regards
greg
