Rebuilding my shack, I'm putting everything on one separate 20amp electrical circuit that I've just added. (2KW+ is more than adequate capacity for the equipment I run.) I had an idea I wanted to get some feedback on from any knowledgeable folks.
What about putting some RFI filtering on that circuit "before" any power plugs? I would set up a junction box containing a toroid onto which both 12 AWG power wires (white and black) are wound several turns. I'd also add a bypass cap (say .01mf, 6Kv) to ground from each side of the mains (i.e. white to green and black to green). Then run the power out of that box to the regular box-mounted AC power plugs. The aim would be to filter out incoming RFI and clean the power a bit - but also outgoing RFI I guess (I'm not intending to generate any of that
I frequently see this kind of choke + bypass caps filtration within power supplies, switchers in particular, (usually with ferrite beads rather than wound toroids).
Anybody done this to a mains circuit? Thoughts pro or con?
