Lights Flickering? When It's Normal vs. When to Worry — what Charleston homeowners should know
Flickering lights have wildly different causes depending on the pattern. Brief dim during AC startup is normal; constant flicker on one circuit is a connection problem; whole-house flicker is a service-side issue.
Most likely causes in Charleston
Brief voltage dip (AC startup, microwave)
When a high-current device starts (AC compressor, microwave, hair dryer), it pulls a current spike. Service voltage drops briefly. Lights dim for 0.5–2 seconds, then recover. NORMAL on most homes.
Most common (transient)Dimmer / LED bulb incompatibility
Old triac-based dimmers + modern LED bulbs = visible flicker, especially at low brightness. Need a dimmer rated 'LED-compatible' (CL/MLV).
CommonLoose neutral connection
Loose neutral wire (at panel or junction box) = unbalanced 120V. One leg drops, lights on that leg flicker; lights on the other leg may go bright. Genuine fire/equipment-damage risk.
CommonFailing breaker or burned panel busbar
Federal Pacific or Zinsco panels: aluminum busbar oxidation creates intermittent connections to breakers. Lights on that circuit flicker as the connection comes and goes.
Less common (FPE/Zinsco)Service-side issue (utility)
Whole-neighborhood flicker = utility issue (transformer, line, weather). Whole-house but only your home flicker = service entrance or main breaker problem.
