Agreed. I would think that the terminals, per se, are virtually always IP2X, but there are at least some in which I think the heads of the terminal screws might protrude enough to be touchable (particularly if there are large and/or many conductors in the terminal.It could happen, but the design of the socket makes it very unlikely, all L/N parts are recessed (IP2X??) on the sockets I've fitted
