It does not let you select a size wire and it does not let you select your wire fill. Its permanently on EMT and it’s not let you choose sizes or types or anything so please fix that developers so we can get back to using it because it really is a great app! ### 4/5 — Conduit body’s *2023-09-06* Great little app Conduit body fill would also be a dig help ### 5/5 — Great app *2021-12-03* Great app to use …. Buddies even call me all the time asking for conduit fill ### 1/5 — Needs correction *2021-06-22* The vast majority of wire insulation I use is T90 or RW90. Perhaps it’s an American thing, I don’t know what most of the insulation types (in this app) are in real world use. Other wire fill apps have the two I need. ### 5/5 — Works great for me *2020-12-15* Works great for me ### 1/5 — App not working. *2018-08-29* I purchased this as a bundle, and this particular app does not work.🤨 ### 1/5 — Confused *2013-12-02* I don't think this app is correct. I was taught to multiply the number of conductors by the approximate area of each size, then divide by 40%. If of course, and in almost every case, your raceway contains 3 or more wires. ### 3/5 — Wrong answer *2013-06-11* After you add wire and conduit fill and get results it gives one size pipe and when you save the results it changes the results down one pipe size. Whats up with this? And which is right? ### 2/5 — Quits unexpectedly *2012-11-23* Quits before I can get the results. Refund please. ### 4/5 — Ibew 46 *2012-05-01* Good app. Any chance of adding a derate function. That would make it perfect. ## Frequently asked questions about Pipe N Wire ### What is Pipe N Wire?
