Overloaded Circuit

When too many devices draw power from the same circuit, the combined load can exceed the circuit's capacity, causing voltage drops that make lights flicker or dim. This is especially common in older homes with fewer circuits.

Steps

1. Identify which circuit the flickering light is on by checking your breaker panel directory.
2. Unplug or turn off high-draw appliances on that circuit, such as space heaters, hair dryers, or window AC units.
3. Observe whether the flickering stops after reducing the load.
4. Redistribute devices across different circuits to balance the electrical load.

When to Call an Electrician

• If the breaker trips frequently, the circuit may need to be upgraded or split.
• Homes with older 60-amp service or aluminum wiring should be evaluated by a licensed electrician for safe capacity.
• Never replace a breaker with a higher-rated one without professional assessment, as this can overheat wiring and cause a fire.
