Question concerning the use of 1” or 1 ¼” EMT. I’ve referenced the NEC tables for conduit fill, but I’m concerned about the ease of the wire pull, and the amp/derating factor, which I am not that familiar with, or if it even applies. Local code requires conduit. This is the set up:
1. Apprx. 11 foot run between service disconnect and panelboard.
2. Two 90 degree bends
3. 100 amp service
4. Feeders #4 copper labeled THHN
5. Bonding #8 insulated labeled THHN
So, for the above application- 1” or 1 ¼” emt? Thanks.
