Wire Pull

[kunk]

Can you tape the Brown/Orange/Yellow #12 THHN together and pull 3 sets of these in a 3/4" Conduit?

 

[mopowr steve]

Do you mean as individual sets or pulling all 9 wires at the same time?

Tape Brn/Org/Yel #12's together as a set and pulling 3 of these sets
into a 3/4" conduit

Shouldn't be a problem, we do that all of the time and then individually number them after the pull.

 

[electrofelon]

Yep, you could even do it in 1/2.

 

[sameguy]

I can.
Do you know B,B,R,O,Y,G,B,V,G,W Color code ? I made it to Violet, bundles for a control wire pull one time, didn't have numbers but had phase tape!

 

[Coppersmith]

Since a ground would also be required, that would be 10 total which does not fit in 1/2" EMT or PVC (longer than 24"). OP didn't specify conduit type.

Wire egc not required for emt, of course....

Ahh. I forgot that. I always pull a ground wire regardless of conduit type. I don't trust EMT connectors/couplings to maintain a solid ground.

Yes. With some adjustment.

.

Table 310.15(B)(3)(a)
7-9 conductor, 70%

#12 use 25 amp X 70% = 17.5 amps

Table 310.15(B)(3)(a)

#12 use 25 amp X 70% = 17.5 amps

Do what you want but if I'm using a 90C conductor such as THHN I'm going to use
30 amps X 70% = 21 amps

What are you terminating that wire on both ends?:huh:

90 degree can be used for derating. 9 CC is the magic number for #14 and #12. So in practice, most of the time, I can pull 3 full boats of 12 or 14 with no derating.

Good point.

Yup 9 CCC's is the magic number where derating will not change the typical 20 OCPD ahead of the #12 AWG conductors.

What's conduit...............

I stand corrected.

Terminal rating is not involved?

Not for conductor derating purposes.

Tape Brn/Org/Yel #12's together as a set and pulling 3 of these sets
into a 3/4" conduit

When I do that I identify each "set" with a different color tape around each set.

BOY insulation is still identifying system/phase, tape color is identifying which individual group of conductors are for which branch circuit.

Please cite the code section where a ground wire is required in EMT?

dont pools and such need insulated EGC (if the work was for a pool)?
besides that, he said he always pulls EGC, doesnt trust the EMT connectors and what not.
