Before I say how I think the Agent may be trying to wriggle out of item 11 being a C2 I want to say that I think the C2 items should be addressed and corrected by the agent and that as has been said previously only doing another EICR can result in a different classification.
Obviously if the RCD does not trip at all at its rated current then it is faulty and should be replaced. Do we have any test results for the RCD?
Anyway here is what I think the agent is trying to use to wriggle out of C2 classification:
First I will assume the RCD is only for additional protection. Then referring to Regulation 643.8 "Effectiveness is deemed to have been verified...disconnects within 40mS when tested at a current equal to or higher than five times its rated residual operating current". So if the RCD disconnected within 40mS at 5x its rated current it is deemed to be effective.
