I have a vauge impression that when certain devices are plugged
into a wall receptical (particularly variable speed AC motors in
laminar flow fume hoods) that the power wires inside the wall
receptacle box are wrapped a few times around a torroidal core
before being screwed onto the recepticle.
Are there any such wall recepticles or boxes that come pre-wired
with RFI filtering to prevent devices (such as fume hoods and tread-
mills) from injecting RFI noise back in the power line?
What devices or components can I wire directly into the breaker
panel to filter EMI / RFI?
Although I would like to see answers to the above questions, my
specific problem is the reduce the noise from a tread-mill from
being picked up be nearby electronic recording equipment.
