Fitted a new consumer unit in my flat for additional safety and installed a 10way split board with two 30mA RCD’s protecting 5ways each.
The RCD protecting the cooker circuit trips when the cooker is switched on, so checked the cooker elements with a 500v insulation tester and found that some have a low resistance to earth and are “leaking” sufficient current to trip the RCD.
Ive been out of the trade for a while now and only have a copy of the 16th edition which seems to stipulate that the downstairs sockets must be protected by a 30mA RCD so Im considering replacing one RCD with a 100mA and connecting the cooker and lights to that side, with all other ccts left on the other 30mA RCD.

Anyone see any problems with this
