Rcd tripping below 30ma

[Bradley6969]

40A 30ma RCD tripping out at 22.5ma, would people say that’s low and acceptable as I’d say it was a bit low should be more like 28ma?

Anything above 15mA and below 30mA is acceptable for a 30mA RCD.

Split the circuit so the earth leakage is less.

Very normal reading in my experience......

RCD's are compliant of they operate at between 50% and 100% of their rated current. A 30mA RCD can trip at 15mA and be acceptable.

Actually, it MUST NOT operate at 15mA, but anything above it is fine so long as it is less than or equal to 30mA.
