Installations are divided into circuits; every submain and final subcircuit starts at a main or distribution switchboard with all its conductors connected at that one switchboard; electric vehicle charging circuits follow Appendix P guidance. Maximum demand is determined by calculation, assessment, limitation or measurement (measured as the highest consumption sustained over 30 minutes in 2018).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
