What is meant by a "Split Load" in a consumer unit?

The lighting can be on the circuit without the RCD, being at very low
risk of zapping you, compared to the power circuit. They did this so
that if the power goes off you still have lighting to find your way
around while looking to fix the power.


Also if you've just had an electric shock, the last thing you or anyone
who might be coming to assist you want's is for the whole house to have
been plunged into darkness.

They really are quite a good idea, and some peoples interpretation of
the 16th edition regs makes them mandatory.
