Size Your Water Heater Circuit Breaker For Safety

What Size Breaker for Water Heater

Water heaters require a specific circuit breaker size to ensure electrical safety. The breaker must be rated for the maximum amperage drawn by the water heater. This amperage is determined by the water heater’s wattage, which can vary depending on the type, size, and performance characteristics. The National Electrical Code (NEC) recommends specific circuit breaker amperage ratings based on the water heater’s wattage. Using an undersized breaker can lead to circuit overloads and fire hazards, while an oversized breaker may not provide adequate protection against electrical faults.
