Power quality in homes built before 1965
Home

Older homes tend to have more power quality problems than newer homes. Age, combined with outdated electrical systems, can contribute to the increased likelihood of problems with electronic equipment.

Prior to 1965, homes were likely to have two-pronged outlets. This means that ground wires were not installed in these outlets. Older style outlets are not adequately wired to provide the basis for maximum safety and power quality because surge protectors have three-pronged outlets. Call a licensed electrician to assure that your outlets are adequately grounded.
