Need another dis-connect or not?
Need another dis-connect or not?
(OP)
We have a customer who is starting to build self contained environmental remendiation trailers for use in Florida. These trailers are similar to the ones you see the lawn maintenance guys use. Inside the trailer will be a compressor, vacuum pump and a couple of liquid pumps. Most of the time they are in a hazardous zone.
The control panel we manufacturer goes on the trailer front(outside) and is a NEMA 4 enclosure (outside the zone). On our panel we have a main dis-connect with a thru door operator made by ABB. This dis-connect is lockable in the off position (padlock). Is our customer required to have dis-connects at each unit inside the trailer ? Most of the time he passes inspection without them. But he has a couple of times in which he had to put dis-connects at the units. Are the additional dis-connects really required the code?
Thanks in advance
