The answer to 'how much does circuit breaker cost' is that the cost can vary significantly depending on several factors. Circuit breakers typically range from $20 to $200 or more, depending on the type, size, and features. The cost is influenced by the electrical capacity, whether it's a basic model or a more advanced smart breaker, and the brand or quality level.
For most standard residential circuit breakers, you can expect to pay between $30 to $100 per breaker. Larger capacity breakers or specialized models like GFCI and AFCI breakers will be on the higher end of that range. The cost can also vary based on your local market and the specific electrical contractor you hire to do the work.
