Hint: “gimme” some support here
Scroll down for the answer.
Using flexible wiring methods such as flexible metal conduit (FMC) is a good choice when it comes to wiring equipment such as motors, compressors, transformers, generators, and other types of equipment that may vibrate, twist, or otherwise have some movement during normal operation. Whatever type of wiring method you decide to use, be sure it complies with the support requirements outlined in the NEC.
Section 348.30(A) requires FMC to be securely fastened within 12 in. of each conduit termination and supported and secured again at a maximum of 4½ ft intervals. The FMC in this photo is not secured within 12 in. of the conduit terminations. For installations where flexibility is needed, such as this motor, Sec. 348.30(A), Exception No. 2, allows for alternative support options. For trade sizes ranging from ½ in. to 1¼ in., the FMC can be installed unsupported for lengths up to 3 ft from the last point where it is securely fastened. The installer of this FMC chose to install zero supports at the 3-ft mark. This length of FMC is closer to 5 ft with no supports other than the connectors at each end.
