For instance, you can pull a maximum of 10 conductors of 10 gauge THHN for 3/4” EMT. For Schedule 40 PVC (which I happened to use for my install) it is 9. I can say from experience, pulling up to the max gets tough if you have a lot of corners to go through.

ALSO, whether bending conduit or using PVC please remember:
  • EACH pull of wire, from one box to another, cannot have more than 180 degrees of bends TOTAL… Each pull…
  • And the closer you come to that 180 degree MAX, the harder it gets to pull.
  • Place junction boxes where you know that the total number of bends will exceed 180 degrees.
  • Don t be tempted to pull wire before you join lengths of pipe/PVC and glue them together afterwards to bypass that 180 Degree max. You will never be able to replace/remove it in the future because it will act as if you had tied a knot in the wire run…

Good luck!

I’ll add that if using EMT, be sure to ream any cuts you make to remove any burrs. I simply use a large twist drill bit in a cordless drill.
