wire fill

[999]

how many #6 conducters can fit in a 2-inch rigid conduit?

 

[celtic]

What type insulation?

Table C8

 

[ptonsparky]

How long is it?

 

[480sparky]

Rigid metal or PVC?

Less than or more than 24"?

 

[ptonsparky]

Schedule 80 or Schedule 40?

 

[celtic]

How many CCC's?
OCPD value?

In football, I think they call this a "Pile-On!"

So how does this impact fill calculations?

When they are miscalculated.

After you get them all in there you will have to derate them.

You could put 26 or 27 THHN/THWN in 2" PVC 40 or RMC. With 21 current carrying conductors you have to derate them to 45%. That would give you an ampacity of 33.75 Amps. To get the rated ampacity of 6 AWG with 3 in a raceway, with that many in the raceway, you would need approximately 2 AWG copper (130 Amps at 90 C with 3 in a raceway).

So the real answer is that you shouldn't even consider filling a 2" conduit with 6 AWG.

More than six (6) current carrying conductors of 6 AWG in a raceway runs you into the law of diminishing returns. Nine CCCs may work under certain load conditions.

I prefer to derate BEFORE I put them in there ...less problems later

OK I see your point and I will keep that in mind for the future.

I think we have now started to "Pile On" Celtic.

"Tag, You're It" meets "Pile-On!"

Think we can cash in for this year's holiday rush?

Now if we can just the the OP to shake out some more info......
