What impact do Title 24 energy standards have on electrical installations?

• A. They dictate energy efficiency requirements for lighting and related systems.
• B. They determine the color codes for wiring.
• C. They govern only the size of service feeders.
• D. They set tax rates for electrical equipment.

Answer: (A)

Title 24 energy standards regulate how much energy lighting and related electrical systems can use in California buildings. They set energy efficiency targets for lighting, require controls such as occupancy sensors, automatic shutoffs, and daylighting strategies, and specify the efficiency and installation rules for fixtures and controls. This shapes electrical installations by determining what types of lighting and controls you can install, how they must operate, and what documentation is needed to prove compliance. Updates happen regularly, so designers and electricians must stay current. They do not set wiring color codes (that's the NEC), do not govern feeder sizes alone, and do not determine tax rates.
