In the United States, residential service is 120 volts for standard outlets and lighting, and 240 volts for high-power appliances like electric ranges and central air conditioning. The panel safely distributes this dual-voltage power to all branch circuits. Your home gets its electrical service from the electric grid, and distributes it to the individual circuits and wall outlets in your home through your home's electrical panel — sometimes called the breaker box, load center, fuse box, distribution center, or distribution box. This rating is most accurately found on the main circuit breaker inside the panel, usually the largest switch located at the top or bottom. Each circuit powers specific areas or appliances. Modern homes. Most home inspection standards require inspectors to determine and report on the voltage and amperage supplied to the home. Basic household voltage in the US is 120V/240V, whereas most IEC countries, including the UK, EU, AUS, and NZ, use a simple 230V single phase and 400-415V.
