Rcd tripping - very odd

[marc8]

Removing the RCD (and replacing it with an 'S' type for that matter) would really require confirming why it was installed in the first place followed by a risk assessment etc. I'm not sure about UK regs (my location is elsewhere) so I can't really comment on that aspect but there could also be in-house requirements of that particular company to consider.

S type would do it as it is time delayed & good point about the risk assessment
