does anyone know of a protecter that can be installed on a furnace, boiler,or in the electrical panel that serves the equipment, to protect it's electronics from poor power quality?
We have a existing building with several furnaces,and a condensing boiler.Over the past five years we have had to replace the circuit boards in all of this equipment,and in most cases the circuit boards have had burn marks were the 115 volts is connected to the board. I can not see any other reason why these boards would be failing unless it is from poor power quality.Thanks to all.

    Are there other electronics in the building suffering a similar fate? Does the building (or another nearby) have large electric motors, welding, or other industrial processes going on?

    Surges are but one of many power quality problems and remedies differ quite a bit depending on the type of issue.

    Anyone ever notice that sometimes, some lights are brighter than normal and other lights are dimmer than normal? And at other times, the brightness and dimness alternate?

    If you do, get out of Dodge. You might have a bad neutral. Don't ever get between a bad Neutral and where it wants to balance out. It can be quite a shocking experience.

    Do they have aluminum feed conductors in the main panel? The connections might need to be tightened. Something that Sparky doesn't always want to do.
