What is the typical current rating for residential circuit breakers?

The typical current rating for residential circuit breakers falls within the range of 15-30 Amps, which makes the choice regarding that range the correct option. In most residential settings, standard circuit breakers are designed to accommodate common household loads. For instance, lighting circuits often use 15 Amp breakers, while outlets and larger appliances may use 20 Amp breakers. This range effectively balances safety with the ability to handle typical household demands, preventing overheating while providing sufficient power for devices.

Lower ratings, such as 5-10 Amps, generally apply to specialized circuits for smaller devices, which are not standard for general residential circuitry. On the other hand, breakers rated 40-60 Amps are typically used for larger appliances, such as electric water heaters or HVAC systems, rather than for general household circuits. Understanding these ratings helps ensure proper protection and functionality for residential electrical systems.
