> You don't get, for example, datacentre electricians rocking up pretenting they can install network cable to spec and running away having (if you are lucky) only done a continuity test on the cable they just installed.

I frequently have my electricians pull and terminate network cable if it’s only one or a few (daisy-chained VAV controllers or a network drop for a BAS panel), if the customer needs a formal TIA-568 test then I’ll sub that out. My electricians are already pulling and terminating building automation cable, CAT 6 isn’t gonna stop em :)
