[TowerTalk] AFCI RFI?

I went thru about 3 sets of Eaton breakers. The problem was not rf but with surge current when I would turn the radio on, they would trip.
I finally took them out and put in regular breakers.

Know that code requires that only breakers of the same manufacturer as the panel be installed.

And yes, EATON certainly did have a problem, to the point they were replacing breakers free if you put in a claim.  If I remember correctly, the problematic breakers had a yellow dot and the replacement design has a white dot.

I purchased Eaton AFCI units and they worked well, except when I got on the radio.  Unfortunately, on transmit, they would all trip.  Eaton received lots of complaints from other consumers and finally came up with a unit that wasn't affected by RFI.  You might consider a call to Eaton tech support for an update or speak to an electrician who has recently used this brand.  Or, perhaps someone here has had more recent experience than I have.

I believe I read somewhere (here, possibly?) that either these or GFCI's were problematic in generating RFI, especially on the lowbands.  I'd like to make sure I don't make things worse for myself by allowing the electrician to install the wrong AFCI design or brand.
