## Questions & Answers

**Q: Is this compatible with the orange ones? I need to add it to my existing board as a new circuit**
A: Hi yes, exactly the same pattern they have justed updated their logo!

**Q: Does this breaker have a reset button**
A: No, there is not a separate reset button.
If there is an overcurrent the breaker will trip and the lever will move to the other position. The breaker is simply reset by moving the lever back. In the event of the breaker clearing a large fault or after clearing several smaller ones the breaker may fail. In this case the breaker will not reset.
You also need to make sure that the failure to reset is not down to faulty wiring on that circuit - the breaker may be doing its job correctly.
Hope that helps,
