lyledunn:Indeed Ebee! Where enhanced resilience is required following the assessment of the risk, it might be difficult to contend that a single RCD is an adequate control measure. Just because 7671 doesn’t require it doesn’t mean it isn’t required!
It is not clear whether the failed RCD was a 300mA, 100mA or 30mA. 705.411.1 mentions all three types.
Assuming it was a 30mA, you would have thought, it being a barn, that 705.422.7 would come into play, and an additional 300mA RCD , possibly time-delayed, would need to have been fitted.
