Calculating the percentage of completion

In electrical installations we use electrical boards just like the ones on your house. Each board can have any number of fuses, mcb’s trip switches. To know if a board is complete each board has to have a number of circuits running from the fuse box. Each board is different. I’m wondering how calculate the percentage of each boards completion and what would the counter solution be to trip -1 for each tested circuit until the tested circuits results in 100% that would trigger a report to be sent to managers containing a pdf with the test results.
