Single Phase 120 volt electrical panels are most commonly found in residential areas on sub-panels (sometimes called branch panels) where 240 volt electrical service is unnecessary.  Since most residential lighting and garage door openers utilize 120 volts, the panels in outbuildings, garages and small workshops are sometimes wired with 120 volts to save cost.; unlike residential main panels that typically require 120/240 volt, split phase systems to provide the extra power required for larger appliances like electric clothes dryers, central air conditioning units, and electric water heaters.

Commercial applications for 120 V panels include storage buildings, building additions for non-electrical manual labor operations, etc.
