Communal DB does it require RCD protection to be a sat EICR

[davesparks]

Isn't C3's only on a an EICR a satisfactory rating anyways?

Usually if there are only C3 observations it would usually be deemed satisfactory but could be found to be unsatisfactory in unusual circumstances.

Whilst any C1,C2 or FI observations automatically result in an unsatisfactory outcome.the reverse is not also true.
