Explosion Proof motors meet Under-writers Laboratories or CSA standards for use in the hazardous (explosive) locations shown
by the UL/CSA label on the motor. The motor user must specify the explosion proof motor required. Locations are considered hazardous because the atmosphere contains or may contain gas, vapor, or dust in explosive quantities. The National Electrical Code (NEC) divides these locations into classes and groups according to the type of explosive agent. The following list has some of the agents in each classification. For a complete list, see Article 500 of the National Electrical Code.

 

 

 

The lines of a three-phase power system may be connected to the terminals of a three-phase motor in several different ways. Which of these altered motor connections will result in the motor reversing direction?

 

 

 

Class I (Gases, Vapors)
Group A Acetylene
Group B Butadiene, ethylene oxide, hydrogen,
propylene oxide
Group C Acetaldehyde, cyclopropane, diethlether,
ethylene, isoprene
Group D Acetone, acrylonitrile, ammonia, benzene,
butane, ethylene dichloride, gasoline,
hexane, methane, methanol, naphtha,
propane, propylene, styrene, toluene, vinyl
acetate, vinyl chloride, xylene
Class II (Combustible Dusts)
Group E Aluminum, magnesium and other metal
dusts with similar characteristics
Group F Carbon black, coke or coal dust
Group G Flour, starch or grain dust
The motor ambient temperature is not to exceed +40°C or -25°C unless the
motor nameplate specifically permits another value. LEESON explosion
proof motors are approved for all classes noted except
Class I, Groups A & B .
