The rules made sense when they were drafted. Forty years ago, a dishwasher

I just learnt from ITS that the crossed-out wheeled bin symbol is no longer

I'm guessing most people wouldn't even know to complain these days if theirs or
their neighbors dishwasher started interfering with their TV or radio.
And TV's with their cable/internet/satellite connections and FM/satellite
radios are a lot more immune to that stuff as well than 40 years ago.

Though the home appliance industry has had their issues in the past, I can
testify this is no longer the case. I work within a few miles of the
headquarters of one of the largest home appliance manufacturers in the world.

After reading this thread, am not certain why functional safety and EMC safety
would not apply to heavy equipment for U.S.
The FCC's scope exception is for transportation vehicles. The Bagger 288 is a
magnificent machine, but 'transport' vehicle is certainly not among its
