Such very large equipment tends to be custom-designed, so three
identical installations never exist. Even if there are three identical
installations, they are unlikely to be completed simultaneously, so how
can the first two be legally operated before the third is installed and
tested?
I wonder if FCC needs to look again at this requirement.

Equipment that is covered under FCC Rules Part 15, but which is too
large to test on an open area test site, can alternatively been tested
in situ. However, the rules state that the test should be performed
at 3 different representative installations of the equipment. Does
anyone on this forum have experience doing this? I would expect
conducted emissions to be reasonably similar, but I can see how
environmental influences could result in 3 different sets of radiated
emissions data. How do you make sense of the data?
