In which situations must a licensed electrician be called for work?

A licensed electrician must be called for work involving new wiring or significant alterations to existing electrical systems due to safety, compliance, and expertise considerations. Electrical work can pose substantial risks, including the potential for electrical fires or personal injury if not done correctly. Licensed electricians are trained to handle such complex tasks, ensuring that installations meet the National Electrical Code (NEC) and local building codes, which are designed to protect both the property and its occupants.

In contrast, minor repairs on existing fixtures, installing battery-operated devices, and changing light bulbs typically do not require the specialized knowledge or licensing that complex electrical work demands. These tasks are generally considered low-risk and within the capabilities of a homeowner or a non-licensed individual, as they do not involve creating or altering electrical systems to the extent that could endanger safety or violate code requirements.
