Hi Guys,

Thanks

The only one I know of with that rating is the X10 XPF 20A.

Maybe Jeff has some other ideas - maybe his ANR would do the job. Is the problem only when in use or all the time?

Thank you Brobin,

I was thinking about XPF. The problem is that I will have to add a plug and connector: plug to connect the filter to the wall and then connector to plug in the microwave.

Alternatively I will open the outlet box, do wiring in the box, and screw the filter to the wall next to the electric outlet.  Either way, it will look messy.

If the microwave is on a dedicated circuit you could put the XPF in the electrical panel.

Yes, this is what I may do. I will have to check if filter in the electric panel does not weaken X10 signal. 

X10 installation and troubleshooting is "rocket science"!!!  -:)

Yes, it causes problems even when idle. I have a 3,000sf house with multiple computers, laptops, chargers, LED bulbs etc... It looks like all interferences and attenuations add up. Maybe the microwave is the straw that breaks camel's back.

Assuming it's a dedicated circuit for the microwave and flipping the breaker solves the noise problem, the XPF is really your only option.  I don't think the XPF installed in the panel would be a problem as I've done something similar in the past with success.  You can get a brand new one on ebay right now for $22 delivered.

This was my solution to your issue. I have made 3 of these. My latest was for a Roomba vacuum that was really noisy. Notice that there is a ground wire running between connectors for 3 wire plugs.

Looks clean! Thank you for sharing!
