My RR501 died

Well if you are handy with a soldering iron it maybe possible.

I just opened my Date Code 02F23 and made a discovery. The fuse only protects the MOV surge protection component, not the whole electronics.

It would be a real fine wire maybe #30 or smaller. Near the power prongs and maybe marked F or FUS.
If X10 updated the board for new components then I can't give you much data.

That makes about as much sense as a fuse protecting a fuse. I think X10 has lost their recipe book.

When a surge protector fails it turns into a low resistance, so there must be some means of interrupting the current to the surge protector.

So the MOV gradually shorts each time it takes a hit? OK fuse makes sense then. But I have seen these single socket supressors with MOV unfused from hot to neutral so assumed the clamp voltage went up and junction opened with each hit. Thanks Jeff

The surge protector will normally clamp a voltage spike somewhat above the peak AC line voltage.  A severe transient can dissipate enough energy in the surge protector for it to fail to a low resistance.

I learned that the hard way with the early XTB-IIR.  Like most X10 equipment, it had 130VAC surge protectors.  Several people managed to get 240V across the 120V input, destroying the surge protector, and popping the fuse (once spectacularly).  It now has 275V surge protectors, so the worst that will happen is the user-replaceable fuse will pop when 240V is applied across the 120V transformer input.

Yes but a 130 volt MOV on 240 makes such a nice big BANG.
Unless you get a piece of it in your face. Don't ask how I know this.

It's in the garbage....farewell RR501....

Then get another one (check out Automated Outlet at http://www.automatedoutlet.com/ )and don't plug it into that multiple outlet the old one was.
