We have a trailer that contains pumping equipment. Outside the trailer in the unclassified area is a control panel and breaker panel. From these boxes, there are several 1" EMT conduits that are piped to a trough under the trailer. There are no seals between the the boxes and the trough.
On the backside of the trough under the trailer are about eight rigid conduits. These conduits go up inside the trailer to the various motors, lights, etc. Again, there are no seals on the rigid conduit.
The inside of the trailer is rated Class I, DIV II. There are/will be seals located within 18" of the arcing devices/motors, etc. Shouldn't there be conduit seals in the rigid piping on the backside of the trough under the trailer in addition to the seals required at the motors, light switches, etc?
Also, inside the trailer are three XP lights mounted in the same conduit as the light switch. Do I have to provide conduit seals on either side of each light or can I have the seal that is "downstream" of the light switch double as the seal for the bank of lights?
thanks for the help
