Bob,

I believe that if this is to be an 'Industrial Control Panel' it would have a

single disconnecting means already incorperated into it. The wording of

409.20 , 409.21 , and 409.110 all reflect that a single disc. is being used,

or maybe a better term , required. If in the OP's case, one feeder is all that

is needed for all the equipment including the hood lights, then I am barking

up the wrong tree,but, by the discription he gave I felt otherwise. 430.102(A)

also requires an individual disc. for a 'controller.

Frank the hood control panels I have installed all had two disconnecting means built in. One for the 480 feed and one for the 120 feed.

Of course I have no idea what the OPs panel really looks like.

Regardless if the unit is covered by 409 or not 430.102(A) applies and requires disconnecting means at the controllers.

The panel is 120/208. With nothing in it other than two contactors, a termination bar, this is it. Which means I will need more than one circuit. One for one fan motor, one for the other fan motor, then one for lighting. what is keeping me from installing switches in this panel, or right beside it? Motor rated switches of course. the disconnect required is for service of the control panel correct?

Bob if this is in fact a contoller it seem it would be a violation of 430.103 as I see it

Frank the hood control panels I have installed all had two disconnecting means built in. One for the 480 feed and one for the 120 feed.

Oops sorry Bob I missed 430.113 but it seems to me if you had a motor 480 volt that you would use a contol transformer to get 120 volt, have one power source, and one disco generally if it is a control panel wired by a 508 shop

The 120 was not just the control power, the hood control panels I have installed generally controlled 2 or 3 - 480 volt motors up on the roof and 2 or 3 - 120 volt motors on the hood itself.
