Industrial Electrical Equipment Manufacturing

Establishments primarily engaged in manufacturing electric motors (except engine starting motors) and power generators, motor generator sets, railway motors and control equipment, and motors, generators, and control equipment for gasoline, electric, and oil-electric buses and trucks. Sample business functions include industrial armatures, motor and generator coils, collector rings for motors and generators, electric motor commutators, control equipment for buses and trucks, phase and rotary converters, electric dynamos (excluding automotive), dynamotors, motor and generator exciter assemblies, and frequency converters for electric generators.

Establishments primarily engaged in manufacturing relays, motor starters and controllers, and other industrial controls and control accessories. Sample business functions include armature relays, magnet and solid-state control circuit devices, industrial control circuit relays, industrial controls and control accessories, controls for adjustable speed drives, crane and hoist controls (including metal mill), electromagnetic brakes and clutches, industrial controls such as push buttons, selector switches, and pilot controls, marine and navy auxiliary controls, and motor control accessories including overload relays.

Establishments primarily engaged in manufacturing industrial and commercial electric apparatus and equipment not elsewhere classified, such as fixed and variable capacitors and rectifiers for industrial applications. Sample business functions include battery chargers (rectifying or nonrotating), AC capacitors for motors and fluorescent lamp ballasts, fixed and variable capacitors (excluding electronic), condensers for motors and generators, fixed and variable condensers (excluding electronic), current collector wheels for trolley rigging, electrochemical generators (fuel cells), nonrotating electrical inverters, mercury arc rectifiers, and static AC-to-DC power conversion units.
