Question:

Re: CQD answer published June 12, 13 & 21, 2019 - Raceway Fill and Adjustment Factor

Just a little help for Bill Neitzel and his search for a conduit fill phone app that does #18 and #16 TFN wires, asked on 06/20/19. I use the app "Conduit Fill Tracker" from "Summit Electric Supply" and it does both #18 and #16 TFN wires. Most wire types like THW, THWN, THHN, etc. will only go down to #14 in the app, but others like TFN, TFFN, XFF, etc. will go down to #18.

Answer:

Hey Richard thanks for sharing information about the phone app that can be used for smaller conductors. I'm sure our readers will find it helpful. Once a size is determined for the specific installation confirming the calculation using the NEC might help avoid problems in the event there are differences or if an earlier NEC is adopted in that area.
