Free Resources – Conduit Bending Handout and
Sizing Conduit or Tubing Spreadsheet

Bill Bamford of Wirelab Services recently updated his 2 informational documents which we offer on our Free Stuff page. Below are links to them and a short description of each.

Bending Conduit/Tubing Using Hand Benders

The conduit bending handout steps the student through the process of hand bending stub-up, offset, back-to-back, 3-point and 4-point saddle bends. It also provides some extra info on bending terminology, making multiple bends on one conduit, bending charts (including examples on calculating final conduit length after bending so that the conduit can be threaded prior to bending).

Sizing Conduit or Tubing per 2011 NEC

The spreadsheet is an Excel spreadsheet. It calculates the conduit/tubing size for any number of up to 10 combinations of wire and or cable sizes. It also warns you if you have the potential for jamming as described in Table 1 Note 2 in Chapter 9. It allows cable size input by either fractions or decimal. It includes all conduit, tubing, conductors (bare, insulated, and compact stranded) providing the same results as Annex C with the addition of the ability to mix conductor and cable sizes.

  • Steve, I added some more features to the conduit sizing spreadsheet including an ability to change the size of the selected conduit. Enjoy. If you find any discrepancies, don't hesitate to let me know so that I can correct them. Mike Holt is very prompt at putting updates on the site. The new spreadsheet should be dated Apr. 4 even though it was updated on the 3rd.
