I am wiring a motor on a machine that has a VFD cabinet. I am going from the drive to the motor with two 4 inch sealtights. My question is do I need have my grounds cover the FLA in each
Sealtight?? I will give an example with easy math
Motor needs 1000 amps, 2 sealtights with 500 amps in them. Does each seal tight need 1000 or
500 amps worth of grounds??

has to be full size, although I am not sure it has to be physically located inside the seal tight.
If it is just a bonding jumper, it would not have to be in the sealtight. If it is an EGC of the wire type that is run with the circuit conductors, it would have to be in the sealtight.

Would 300.2 (1) and 250.122 (A) and (F) be the correct refference?
