Belts Sizes
If you have an engine that must continue to adapt to different sizes of belts,?
What is the maximum length of metal conduit flexible, you can use before driving requires fixing? B. A 10 feet 3 ft c. 4 1 / 2 feet d. 1ft
I assume you mean the requirements of the U.S. National Electrical Code. The 2005 edition of the Code states in section 348.30 that, where flexibility is required, metal duct type FMC may be run 3 feet before being fixed for sizes 1 / 2 to 1-1/4 ", 4 feet for sizes 1-1/2 to 2" and 5 feet for sizes 2 inches and more. All sizes liquidtight LFMC flexible metal conduit type may be executing 3 feet before being fixed, if flexibility is required. Added note: The 2008 NEC requirements for Type FMC is the same as the requirements of NEC 2005. In 2008, the requirements of type NEC LFMC are the same as the requirements of type CME.
