Which option reduces electrical loads by scheduling device usage?

• A. Install timers on devices
• B. Use space heaters
• C. Leave devices on standby
• D. Overload circuits

Answer: (A)

Scheduling device use with timers is a direct way to manage electricity demand. Timers automate when a device turns on and off, so heavy loads don’t all run at the same time and can be shifted to off-peak or lower-demand periods. This practice, often called load shifting, lowers the peak load on the electrical system, which can reduce energy costs and lessen strain on circuits. It also minimizes wasted energy from running equipment when it isn’t needed.

The other options don’t achieve this goal: space heaters add more load rather than reduce it, leaving devices on standby still consumes power even if not actively used, and deliberately overloading circuits is dangerous and illegal.
