Our home was built 4 years ago. We have the same problem. Also, one of the switches in the master suite evidently arcs a bit as that also trips the d$%^& breaker as you describe. RF also gets to it.

Many, if not most, of the offending Chinese RFI generators come through Customs as a 'component'. As such, there is no RFI/EMC requirement for compliance to FCC rules and regulations. The burden of p

The usual and almost ubiquitous answer to taming an RFI noisy Ethernet switch (and a lot more) is, "Put it in a Faraday Cage". Well, guys and gals, as Ed wrote, there's a WHOLE lot MORE to it that th

Good luck!! One bit of advice: Do NOT incorporate 'optimizers' in your installation. They have proven to be extremely noisy - even worse than the inverters+ +. I have contacted a local installer seve

Ferrites are better suited at reducing RFI at 30 MHz than low HF. I am far more concerned about 160, 80, and 40-meters, and of course, 20.1 MHz that 30 MHz. Inverters and built-in or added after the

I believe the diagnosis of a SWPS is highly likely correct. The pointers given are also excellent. Don't forget, once you've located an area, a battery-powered portable radio is 'your friend'. Dave -

Suggest treating every conductor that enters or leaves your charger with a large and appropriate core of ferrite material. Choose the ferrite for frequencies in the lower HF spectrum. 75 material wou
