First of all there should be a consultant who has prepared specifications,drawings,BOQ etc

There should be a contract and programme of work approved by consultant

Shop drawings should be approved.

Check material according to specifications and BOQ,submit samples for approval

Start installation in the presence of consultant

Then lay cables and connect as per drawing

If you notice any discrepancies in the drawing report to consultant and get amended

Let consultant do a visual inspection and clear any remarks

Afterwards test(primary/secondary) injection for relays,oil,CB,battery,alarms,earth etc in the presence of consultant

After test results were approved by consultant you may energise section by section
