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.

Would it be better to use plastic or metal junction box?
In the electrical trade it makes no difference which type of box you use. Both types are approved to be used as an electrical junction box. If the object is to keep costs down go with the plastic box. In harsher environments plastic boxes are used along with PVC plastic conduit.
