Disconnect as raceway

[travis301]

Greetings members,
Do you see a problem with an exterior 4x disconnect used for the A/C unit having a bell box out of the bottom of it for mounting a recept? The recept wires would feed thru the disconnect via a conduit (along with the A/C wires) entering the top of disconnect.Any violations?

I don't see any problem with it.

If you shut down the breaker feeding the dissconnect , all power should be off , in your senerio it would still have hot conductors in it..... anyone ?

That shouldn't be a problem. In fact they make disconnects with an integral GFCI receptacle. Here is one such item:

It is not a code violation.

I have done it and see no hazard.No reason for any joints in it,just let the wires pass thru.

Is there a compliant way to have the disco supply conductors also supply the receptacle (aside from requiring a neutral, of course)?

Unlikely but if the breaker was a 20 amp and the equipment uses less than 50% then sure.

As you said, "unlikely."

Would the disconnect have to be listed as a raceway?

I ran power to a Cambridge RTU on a job last summer. I brought the 480v and the 120v for the service recep. into the control box then dropped out of there to the plug. Inspector passed it but said some inspectors won't unless you can show proof the box is also listed as a raceway. Would you guys agree?

I wired 10 units exactly like this on that job and was happy it didn't turn into a big deal.

I would ask the inspector where the requirement is that it has to be listed as a raceway.

Panels can be used as a raceway so why not a disconnect ?

I would say that it's up to the inspector to show that it is not listed as a raceway in this scenario.
