What else can I help you with?
Why are you only allowed 360 degrees of bend jn a electrcal condit run?
Any more than four 90 degree bents (equaling up to 360 degrees) or a combination of other bends will make it quite difficult to pull the wires into that pipe. This is why the electrical code prohibits more than 360 degrees. If you have to put more bends than that, place a junction box on the line after the first 360 degrees. This way you pull to the junction box and then use that junction box so continue the rest of the way.

How do you size a junction box?
There is no minimum height for junction boxes per NEC. Any use of a junction box that would be subjected to harsh conditions because of its height would have to be rated for the condition. Personally, in outdoor areas, I like to keep boxes at least 18" above grade in areas that get snow.
Do you need to use a Myers hub if you penetrate the bottom of a NEMA 3R junction box with rigid conduit?

What are the best installation tips for a wall mount junction box?

How to extend a wire if an existing wire is short in the junction box?
The answer depends on what type of access you have to the junction box. The wire external to the box may have some slack that can be brought into the box. If everything is tight you will probably have to install one or more additional junction boxes or rerun wire from electric panel. As an example assume that the short wire has no external slack, but you can install a new junction box near the other box and in the path of the short wire. 1. Pull the short wire from existing junction box. 2. Install new box in path of short wire so more slack will be available in the additional junction box; and pull wire into new box. 3. Run a wire of the same size from new to old box and re-splice any connections for original short wire or new connections; and connect this new wire to the original short wire in the new box. Make sure you follow all code requirements for your locale.
