My house surge protector (outside ) began to make a high pitched noise. My hubby called SECO and learned it was the protector telling us it had done its job and been "used" . We did not know that once it does it's job it needs to be replaced for the possible next time. No electronics were affected thank goodness. Just thought people should know about the noise and need for replacement. The company came right away and replaced ,(no charge for replacement.) We do pay the $4.00 per month to have it.
FYI
We have learned that due to the saturated ground , electrical charges travel farther from the original contact point .
