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

  • Best practise guide 4 indicates a C3 , however i would check for induction hobs led light fittings ,so called inverter machines (washing etc) ,heat pumps with variable speed drives and much more that can inject a level of dc .i would also switch any likely items on and test the (RCD) Residual Current Device in a more realistic setting.
