   There are a lot of places that'll sell you a device with one MOV accross 
the hot and neutral lines; however, you want 120V MOVs between hot and 
netural and between hot and ground, and a much lower (30V?) MOV between 
neutral and ground.

   Unfortunately, there is no way to test if an MOV is still working, short 
of trying it... which might kill it and you wouldn't know until the next 
surge came along!

   Careful choice of fuse *might* also help.

The mile is traversed not by a single leap, but by a procession of coherent 
steps; those who insist on making the trip in a single element will be
failing long after you and I have discovered new worlds. -- me
