I am going to use pvc conduit, water tight pull boxes and CGB's for every factory corded device. I will use water proof conductor cable which will be installed in the pvc. Any issues with this setup?

CGB would not be suitable for a wet location. Instead use CGFP. Also make sure you use PVC boxes with hubs for directly gluing in the pipe and not a threaded TA.

What type of cable are you planing to put in the raceway?

It is a code violation to put flexible cord (SO) in raceways.


400.8 Uses Not Permitted. Unless specifically permitted
in 400.7, flexible cords and cables shall not be used for the
following:

(6) Where installed in raceways, except as otherwise permitted
in this Code

It is not 'otherwise permitted' for your application.

Is a green house necessarily considered a wet location?

It may have areas that are wet location, doesn't mean the entire facility is a wet location.

By design one could possibly designate the whole thing as wet - just in case - but only issue with NEC is what is deemed to be wet.

Dry locations according to NEC definition can still be subject to wet or dampness - just not on a regular basis.

NEC may not consider it a wet location. But, when it looks like a giant swamp cooler, and has at least 50% humidity, and a 4 X 30 linear foot wet wall should it be qualified as a wet location?

While this may sound overly simplistic, you really need to look at this situation like this-if it will be generally damp/wet, and you feel that gfci is necessary, it probably is.

It is interesting that every septic system with a pump, alarms and float switches come with a rubber cord. We always sleeve a 2" pvc and run the wires up to the control box. Not sure of a better way to do this. I guess this is really a sleeve and not a raceway

:thumbsup:

See it pretty often, it seems to be a widely accepted violation.
