Hook it to the refrigerator to start with and if you still get devices
tripping, put it on the devices.

Are you sure it is a spike or is it possiable the refrigerator is
drawing enough current to drop the voltage ? A friend had a loose
neutral on his power line. One side would have low voltage and the
other would have high voltage. He had to get the power company to
correct it.
