wall mount sign

[Adams14]

I,m wiring up marquee sign with Ethernet cable. I would like to use 12-2 MC & Ethernet cables through the same 1-1/4 PVC LB and Shed 80 conduit. The OD of the 12-2 MC cable is .475 and is considered one conductor per NEC one conductor can use 53% conduit =.656 space in 1-1/4,shed 80 PVC. I also tested 12-2 MC cable in a 1-1/4 LB no problem.

I have no been able to find bend radius of 12-2 MC cable, and is it OK to have MC cable and Ethernet cable in the same conduit?

See 330.24.

Is it allowed to run two feet of MC cable in the same conduit as Ethernet cable?

Two different "cable" methods in a raceway is not a problem code wise. Power "conductors" (not a stand alone wiring method) and communications cables in same raceway is. It is no different then running them through same space in a building.

The two cables usually would need to separate wherever they terminate though, so you likely can not bring the raceway directly into the sign, but rather use it as a sleeve for physical protection and/or for appearance reasons.

Just using LB and conduit to protect wires from physical damage through brick wall.
