After the big hurricane goes through and takes out all the communications lines and cell phone towers for a 100,000 people then they get a better standing for the Ham operators at least.

Sounds like it would be FCC part 15 exempt providing the user stops operating the device upon a finding by the Commission or its representative that the device is causing harmful interference.

Most of these basic model saws have no high frequency devices and brushless AC motors so they do not generate EMI. However, the more expensive models have Inverters (Frequency Drives) to slow start/stop the motor and act as a break. We evaluated a saw from a company who says they do not require EMC testing on their saws even when they use the Inverter, as long as they follow the installation instructions from the inverter manufacturer (yea, I just about fell out of my chair). We tested one of these saws and failed CISPR 11 Class A Conducted Emissions by 50db (if was a prototype saw not on the market). How do these people sleep at night? So here is my question. Does the US and Canada require Emissions testing on Industrial Saws? Same question for Europe. I assume EN 55011 Class A is mandatory in Europe on such a devices. Please confirm (sanity check).
