NCCER Module 26204-17 Conduit bending fully solved graded A+ 2023/2024

NCCER Module 26204-17 Conduit bendingmust be included when calculating degrees between pull points Offsets and Saddles use the larger size for both conduits To make matching bends in different size conduit using a mechanical bender plugs and air pressure To prevent flattening when bending larger diameter PVC conduit, use 60 to 180-degrees of bend, depending on the type of bends A saddle bend is counted as 40 You are making a 20-inch offset with two 30 degree bends. The distance between bends is _________ inches. the amount of travel method to monitor each bend One method of bending segments is to use _______. 13 inches The minimum bending radius for 3 in RMC is 2" EMT A mechanical bender may be used to make bends in Radius of inner pipe + OD of inner pipe + spacing How do you find the radius of the outer pipe in a concentric bend? it is difficult to bend consistently and accurately A disadvantage of aluminum conduit is that spring-back in order to make a 90 degree bend in RMC, the conduit is bent to 95 degrees to account for provide proper ventilation to carry off fumes from the joint cement An important safety precaution to use when working with PVC conduit is to three A saddle to cross a single pipe typically requires ____________ bends. 4 The minimum bending radius for 1/2" rigid conduit is __________ inches. cross an obstacle The reason for making a saddle bend in a run of conduit is to ________________________. kick A bend used for a change in direction of less than 90o is called a(n) ________________. C=2piR The equation used to calculate the circumference of a circle is concentric bends Two or more parallel bends that are bent in the same direction are known as _______________. offset The type of bend required where conduit enters a panelboard is most likely a(n) ________________. prevent the conduit form wrinkling or flattening during bending Airtight plugs are installed in the ends of large sizes of PVC conduit during bending to _____________. chapter 3 In which chapter of the NEC(C) will you find the installation requirements for conduit?
