AC Type RCD No PV or Car Charger C3 or C2

For a standard domestic Install, split board with 2x Type AC main switches.

No PV or Car Chargers should this be a C3 or C2?

Thanks in advance

  • Indeed .. (from memory the point was expanded on further down - assuming it's the same one I saw a while ago). (Continuing from an earlier discussion) given the human body isn't particularly less sensitive to currents at slightly higher frequencies, do these devices provide adequate additional protection? (I'm not doubting the comply with standards, but the standards were set on the assumption of 50Hz currents only).
