Control and monitoring work turns a distribution system into something you can actually see. Meter hierarchies, alarm points and operator interfaces are designed around the decisions the site needs to make.
Commissioning records, point lists and operator notes are handed over so the system stays useful after the installers leave.
Equipment duty, installation conditions, available fault current, control interfaces and expansion plans all affect the specification. Agree the required drawings, tests and handover records before placing an order.

Start with the equipment duty. Add the control, protection and measurement functions that your project needs; these are options to review, not a pre-approved assembly.
