The electrical line after the meter feeds the entire home or unit. If the cable, contacts, or panel are weak, voltage drops, heating, and breaker trips may appear.
An electrician checks cable size, main breaker condition, terminal tightness, circuit grouping, and voltage under load.
Whole-home flickering, panel heat, burning smell, and repeated breaker trips require professional diagnostics.
During renovation, when adding high-power appliances, or when voltage problems repeat, the line after the meter and panel should be checked.
