Panels confess slowly. Breakers warm under ordinary load, a faint buzzing that comes and goes with appliances, a burning or fishy odor near the panel, rust blooming inside the door in a coastal garage, and breakers that trip and then feel loose on reset: each is a finding, and together they are a replacement plan with a date on it.
The Summerville panel guide starts from the market's own economy: changeouts are a lead service here because the findings are common. Warm breakers, a panel at capacity with tandem breakers doubled into slots, a maker's name from the eras insurers now question, and the arithmetic of new loads on old service sizes. The guide's verdict structure is the market's: some panels are plans, priced and permitted at leisure; some are calls today. Knowing which yours is costs a diagnosis and pays for itself at the next transaction either way.
Era matters as much as symptoms. Panels and breaker lines from certain decades carry documented failure records that insurers and inspectors know by name, and a home can run for years on one before the failure mode arrives. An assessment that reads the panel's make and era alongside its condition is giving you the whole picture; condition alone is half of it.
The line between plan and call today: warm and working is a plan for this season. Hot, buzzing under no load, smelling, or scorching is a call today, with hands off the panel until it is assessed. Panels are the one part of a home's electrical system where curiosity should be scheduled, not spontaneous.
