What is Single Phase?
Single Phase refers to an electrical power supply that uses a single alternating voltage cycle, typically delivered through two wires—one hot and one neutral. It’s the standard form of power in most residential homes, providing 120V or 240V depending on the system setup.
This setup is ideal for powering common household appliances such as lighting, refrigerators, air conditioners, and televisions. Electricians often install or troubleshoot Single Phase systems during home renovations, service upgrades, or electrical repairs. In contrast to three-phase systems used in commercial or industrial buildings, Single Phase is more cost-effective and simpler to maintain, but it’s limited in capacity.
