We are running a subpanel from the outside of the building to the garage. The 2" metalic conduit will begin from the top of a 3R box's raintight hub, run up the building about 8ft, turn right, and then turn again into the attic space before running about 50ft to the garage.
We would like to avoid IMC all the way because it is more expensive. As another option, we're considering starting with IMC and transitioning to EMT:
- What should we consider when deciding whether to go EMT all the way, or to start with IMC and transition to EMT?
- If we transition inside, what type of transition would you recommend to go from IMC to EMT?
- When we turn into the building, can pre-bent swept 90-degree conduit segments be used so we can easily pull the wire, or do we need to use a hard-90 with a wire-pull-hatch? If swept is possible, how would you mount it?
Thank you for your help!
