But If you are going to put MTI PRODUCT in the hazardous location, you must have the Explosion Protection at your own risk. And it is recommended to pass Underwriters Laboratories (U.L.) and the Canadian Standards Association (CSA) certificate at your cost.

Please learn NFPA70 National Electric Code (NEC) and C22.1 for use in Division based hazardous locations and information NEMA explosion proof motors.

                                                                                                                                                    NEMA explosion proof AC and DC motors

Motors misapplied in hazardous environments can cause a fire or explosion resulting in the destruction of property, serious injury or death. Only the end user or a qualified underwriter is to identify and select the proper class, group, division, and temperature code motor to meet the requirements of each installation.

Division - defines how often the potentially explosive materials are present during normal operating conditions.
Division 1: Ignitable concentrations are present all or most of the time
Division 2: Ignitable concentrations are not likely to be present during normal operation


2. Classes and groups - define the type of potentially explosive atmosphere and the specific materials it contains. 

3. Surface temperatures

The “T” Code identifies the maximum absolute motor surface temperature that will be developed under all conditions of operation  and is chosen to be below the ignition temperature of the potentially explosive material in the hazardous area. Surface temperatures of explosion proof motors will not exceed the following UL and CSA maximums under fault conditions.
