It looks like a RCD, it feels like a RCD and it smells like a RCD. Crabtree BS4293.

    I looked at it and decided the RCD sensing coil needs to raise the voltage on the ELCB earth terminal to 50 volts to fire it off.


    Is that possible? 


    Modern RCD testers limit the touch voltage to below 50 volts, so are they brutal enough to hit this device hard enough to make it trip?
