Canada, Mexico and the United States all use a 100–127 volt, 60 hertz electrical system, (as do some other central and South American countries), which shares the same physical connectors. Most of Africa, Asia and Europe use a 220–240 volt, 50 hertz electrical system, with a variety of differing physical connectors.
The utilization categories category for low-voltage switchgear defines the characteristic operating conditions for switchgear such as contactors, circuit-breakers, circuit-breaker-fuse units, contactor relays, etc. These devices are dimensioned for different electrical loads and for different operating conditions.
