Type-A RCD failing 180 degree ramp test

Former Community Member over 5 years ago

Hi

We are testing a type-A RCD (see image: "ABB") with a METREL MI 3152 (see image: "MI 3152 test").

As the image shows, the ramp test (I delta) is failing to trip the RCD for the negative half wave.

Have oneone seen this before?

We have tested other RCDs of this type that have passed, but it seems to only be related to this specific installation type.

Hi seko, could you clarify if you mean it is related to this specific installation, or it has happened before on this type of installation?

Is it a new installation verification or an EICR or another purpose?

It has happened before "on this type of installation". It is a new installation.
