Which code does this activity belong in?
Motor and Generator Manufacturing comprises establishments that produce electric motors, power generators, and motor generator sets for converting or generating electrical energy, distinct from transformers that regulate voltage without converting current type. This code excludes starting motors for internal combustion engines and battery charging alternators, which are classified elsewhere in automotive component manufacturing. Establishments in this industry may also perform factory-basis armature rewinding services. The boundary separates motor and generator production from Power, Distribution, and Specialty Transformer Manufacturing, which handles voltage regulation; from Switchgear and Switchboard Apparatus Manufacturing, which covers protective and distribution equipment; and from Relay and Industrial Control Manufacturing, which produces control devices and starters.
