Validating 3 phase roof-top extractor fans

In this video we've been tasked with validating 16 circuits that supply high level extract fans in a distribution warehouse, with the objective of ensuring it was just the fans not working rather then the circuits.

The cables come from a MCC panel before making their way to a roof, we show how we trace and validate stuff like this and also show bit of testing.
