Honest question, if you know an AC rcd may not work in a fault situation, explain why you would code it as a C3 and negate the need for someone to fix it.
If the RCD is there for additional protection then it is possible that it should be a C3 as it is additional protection and not the primary protection which is potentially compromised.
If there is a definate, confirmed presence of DC leakage currents which will alter the operation of a type AC RCD then that is a different story to guessing that there maybe might be an issue.
Imagine a child sticks their finger in a lamp holder? But the rcd fails…
An RCD is unlikely to assist in that situation anyway. If a child sticks their finger in a lampholder then they are more likely to make contact with both the live and neutral, this will result in current flowing through their finger which the RCD will see as normal load current.
