Head torch, spare batts, and battery power tools that are *charged* ;-)

So, the one technical question that I have. I would imagine that 4mm
singles should be adequate to link the DIN terminals to the RCBOs,
certainly OK for lighting, but should I be thinking of 6mm for some of
the others?

IME RCBOs will come with the required fly lead to connect back to the
neutral bus bar.



JOOI what's the part P situation regarding this nowadays changing a
Consumer unit?..
