OP: Also note that at this wire gauge you are allowed to re-mark a conductor across the "hots" and "not hots" color boundary.

Electrical - AC & DC - junction box/ pull box question outdoor wiring - I am using #6 wire going about 100 feet to a subpanel ( carrying 220 volt). I would like to install one or 2 pull boxes / junction boxes along the way. I am using schedule 40 pvc which is one and a quarter inch size for the majority of the run. Yes, you can do that all day. It's a regular trick of mine. What's more, if pass-through is the only thing happening in the junction box, it counts legally as a conduit body, and cubic inches fall under conduit body rules rather than box-fill rules, which means you can put a lot more wires "through" it.. All things being equal, not splicing a wire is better than splicing it for no .A conduit run with _____ is acceptable to pull wire. two 90° bends, two 45° bends, and two 30° bends.

Where is this "slack" coming from? Wires need to extend 6 to 8" beyond the box for switches and outlets.

conduit hub configurations
When I fish my wires through the 1/2" emt conduit to the 90 degree pull elbow box outlet, the wire coverings are a little shredded. They are not kinked. Should I be concerned about the wire covering shredding? Or should I try it again using a pull elbow box that has opening? How do electricians do it if they weren't using an open cover?
There is no practical limit to the number of wires in a box used that way, because it is subject to the conduit body rules. However if you put a splice in the box, it is now subject to the junction box rules which have cubic-inch fill limits, 2.25 cubic inches per #12 wire passing through or being spliced. That limits a 4x4 box to 9 wires. I Don't Know What Kind Of Formula That The Manufactures Use To Get The Max # Of Conductors In A Condulet. If You Use Table 5 In Chapter 9. A 3/0 Conductor With A Thhn-2 Insulation Is Aprox ..2679 Sq In. 3 X . 2679= .80 Sq. In.
