I have taken all make or break contacts (including two automotive relays, a PLC, a fuse and a 12 volt PMDC motor) and mounted them in a box. This box is then turned on its head and placed in another box. The outer box is filled with commercial motor oil to seal the perimitter of the box containing the circuit. The only thing leaving this box are some wire leads to inert devices and 3 magnetic reed switches. This device is a self contained and self propelled and goes through a spray booth where solvents will be sprayed.
Will this oil seal, with it ability to separate the two environments, work for Class 1 Division 1 locations?
