Southwire® Conduit Fill Calc

Typed all info but no results!!

This app is so quick and easy. Gives you the option to punch in the numbers of your wire properties. For example the wire, size, insulation, AWG , and stranded or solid. It tells you the probability of a jam. All you have to do is put the numbers in. Great app. Highly recommend it.

Length of conduit would be helpful

App isn’t bad for calculating conduit fill but the jam probability is not accurate at all

Excellent tool to use as a Building Inspector

Thanks for easy work

Changing the conduit type erases the conduit size. Many common conductor sizes and types are omitted such as bare solid copper and other that Southwire sells.

Don’t use this app! I work as an electrician and used this app for a conduit fill on a nipple between two panels. I had (4) 350 xhhw and (1) 1/0 xhhw and it came out to 56% fill for a 2 inch emt. Used a 2 inch emt for my nipple and inspector called me on it. I calculated it out via 2020 nec and sure enough it came out to 67% fill over the 60% max. Made me look stupid and wasted time. We’re trained to trust our tools but apparently you can’t this one.

I love this app, perfect for DIY.

I like the fact that I can build my one cable data if needed.
