A 30-amp circuit that runs warm without tripping is a service call waiting to happen — and in older homes where the panel hasn't been touched in 30 years, those breakers are often running past their service life. If you're troubleshooting or adding a circuit, the correct amp rating matters more than picking the cheapest option. Homeline 1-pole 30-amp breaker in 1-inch format for standard residential load centers. Handles 30-amp dedicated circuits for ranges, dryers, water heaters, or AC disconnect feeds. 10,000 AIC interrupt rating handles fault conditions within the panel's fault current capacity. Correct amp rating ensures the breaker protects the wire — a 20-amp breaker on a 30-amp circuit won't trip when it should, a 40-amp breaker trips unnecessarily and runs hot.
