FAQs

• Does the GFP breaker need to match my string voltage the same as a DC breaker?
  Yes, the GFP breaker must match the string voltage the same as a DC breaker, however, the GFP breaker is not allowed as a disconnect and will not provide overcurrent protection.
• Can I have two breakers on the same circuit, such as a DC breaker and a GFP breaker?
  Yes, you can have two breakers on the same circuit. The DC breaker can act as a disconnect and will provide overcurrent protection, whereas the GFP breaker will provide ground-fault protection.
