Our mcc panel at our facility had degraded to the point that it needed to be replaced.
we are running 5 motors of the starters in the mcc panel i intend to replace the panel with vfd's that being said i was going to run a 2 inch conduit from the main breaker box to a wireway ( total run of pipe 60' ) pull in my 24 # 12 awg conductors
three hots and a ground for each vfd then i would like to pull another 24 #12 awg conductors through the same conduit out of the vfd's to run the motors.
two questions do i need to pull a ground for each vfd and is pulling the incoming and outgoing power through the same conduit a bad idea.
i called ac tech and they said i might get some noise on the line but it should be fine but i just wanted to double check with you guys.
p.s. i'm a newbiesorry if i insult anyones intelligence and thank you mike holt your books got me to the point where i can proudly tell my dad i'm a master electrician.
