Electrical conduit bending chart
Well, you were partially right. The stub up deductions are much greater with the larger conduit. A typical 3/4" bender would have a deduction of 6" for a 90 degree bend. A piece of 3.5" on a 881 would have a deduction around 21" for a 90 degree bend.† UL Standard for Electrical Rigid Metal Conduit – Steel, UL 6 † National Electrical Code® 2011 Article 344 † Federal Specification WW-C-581 (Class 1 Type A) † ANSI/ASME B.1.20.1-1983, Standard for Pipe Threads, General Purpose (Inch) † Rigid Metal Conduit Elbows are Hot-Dip Galvanized Rigid Metal Conduit (ERMC-S)-Steel Elbows:
