[RFI] Question: Conducted vs. Radiated Emissions

All:

I have a question regarding FCC limits on conducted emissions that 
relates to radiated emissions.

If a solar panel system produces electromagnetic energy that finds its 
way onto the mains and then onto the power lines which then radiates 
over the air, that device would be subject to the limits imposed on 
conducted emissions.

If the same solar panel system radiates the same energy over the air 
through the cables that make up the system without reaching the mains, 
FCC regulations would not apply since there are no limits on radiated 
emissions.

In a situation where both cases produced the same high level of RFI, 
what course of action would the FCC take? Would they simply dismiss the 
radiated emissions case and enforce the conductive case simply because 
of route the energy took?
