Gentlemen, I am in the process of planning moves for several machines in an industrial facility. Most of these machines will again move at least once or twice in the next 2 years. After reviewing this forum, the code including articles 368, 400.7 and 8, I see no reason not to wire each machine with properly sized protection, and a continuous Bus Drop Cable following the path below.
*Fused bus plug to
*Bus Drop Cable supported < every 8? to
*a suitable tension take-up support device
*attached to the building by an approved means
*same Bus Drop Cable installed as a vertical riser from the tension take-up support device to the equipment served
*strain relief cable grips provided for the cable at the busway plug-in device, support device and equipment terminations
*same Bus Drop Cable hardwired to an enclosed fused disconnect already mounted to the side of the machine
Is an attachment plug required on the equipment termination side? (seems redundant to the separate enclosed disconnect already mounted to the side of the machine) For some but not all machines I will need to prevent the transmission of vibration by using this method.
Thanks for your help and interpretations.
