Recommended circuit breaker amps for small 6.5 kva generator
When selecting a circuit breaker for a small 6.5 kVA generator, you'll want to consider the maximum current output of the generator and the type of load it will be powering. Here are some general guidelines to help you choose the right circuit breaker:
- Maximum current output of the generator: A 6.5 kVA generator typically produces around 8-10 amps of current at 120V (assuming a 60% load factor). To be safe, you may want to consider a circuit breaker with a rating slightly higher than this, such as 15-20 amps.
- Type of load: If the generator will be powering resistive loads like lights, appliances, and computers, a 15-20 amp circuit breaker should be sufficient. However, if the generator will be powering inductive loads like motors, pumps, or compressors, you may need a higher-rated circuit breaker (e.g., 30-40 amps) to account for the higher inrush current.
- Voltage rating: Make sure the circuit breaker is rated for the same voltage as your generator (120V in this case).
Based on these considerations, here are some recommended circuit breaker amp ratings for a small 6.5 kVA generator:
- For resistive loads (lights, appliances, computers): 15-20 amps (e.g., Square D QO15 or Siemens Q30015)
- For inductive loads (motors, pumps, compressors): 30-40 amps (e.g., Square D QO30 or Siemens Q30030)
- For general-purpose use: 20-30 amps (e.g., Square D QO20 or Siemens Q30020)
Remember to always check the manufacturer's specifications for the generator and the circuit breaker to ensure compatibility and compliance with safety standards. Additionally, it's a good idea to consult with a licensed electrician if you're unsure about the specific requirements for your application.
