##Usage instructions
## Usage instructions

1) Do NOT set up without prior training.
2) Always test before use.
a. Only the 10mA RCCB should trip
b. If it does not, there may be a problem with the external Earth connection or with this tool. Do not continue to use.
3) All other RK electrical connections will be connected through this.

This is an improvement of the [10ma-rcbo-and-anti-external-cb-trip](../10ma-rcbo-and-anti-external-cb-trip/) with 2 extra MCBs. As of September 2016, I have dropped the use of the B3 MCB as it is too sensitive for typical use. It is left unconnected in the box.

3. Only test MCB if you are ready for a trip of your onsite MCB.
4. All other RK electrical connections will be connected through this.
5. If the “B6 MCB” keeps tripping due to high-current appliance, you can temporarily engage the “Bypass B6 MCB” switch.

Tool to prevent circuit breaker trips on both 10mA and 30mA residual current breakers when encountering appliances with earth leakage. An LED indicator will display when an earth leak is detected. This tool should be used in conjunction with the [10mA RCBO](../10ma-rcbo) connected somewhere upstream.
