  • Replied in Suggestion
    So that multiport protector must be on the toaster, every dimmer switch, dishwasher, each LED and CFL bulb, furnace, vacuum cleaner, each smoke detector, central air conditioner, .... Or read the ...
  • Replied in Suggestion
    You can read all 61 pages in that IEEE brochure.  It demonstrates how a plug-in protector (too close to appliances and too far from earth ground) make appliance damage easier.  It even provides a ...
  • Damage from brownouts is another popular urban myth.  If a brownout causes hardware damage, then that post also identified each electronic part damaged by a brownout.  With numbers from its ...
  • Please learn to read. Your constant denials of well proven science has been insulting. I have been patient even when your own citation (an IEEE brochure) contradicts what you believe.  You do not ...
  • Please first learn superposition - what is taught to first year EEs. A battery is electrically similar to a wire to that type current. I did not think I had to keep repeating well understood ...
  • Did you know what APC finally admitted? Some 15 million APC protectors are so dangerous as to be removed immediately. APC was making protectors that created house fires. APC choose to also ignore ...
  • Concept taught to first years engineers: superposition. That battery acts like a wire to connect a surge directly into attached appliances. That battery clearly does not act like a capacitor. That ...
  • If protection is not for lightning, then appliances are at risk from all potentially destructive surges.  If using plug-in protectors, then appliance damage even from smaller surges may be easier. ...
  • Periodically, all manufacturer encounter reliability problems. For example, Seagate finally shut down one factory for something like four months to fix reliability problems. And, BTW, we all learn ...
  • Include what is always missing in subjective recommendation (also called scams). Numbers. How many joules does a power strip claim to absorb? Thousand? How many joules does the UPS claim to absorb? ...
  • This 120 volt UPS is promoted as a pure sine wave UPS.  It outputs 200 volt square waves with spikes up to 270 volts.  They did not lie.  As taught in high school math, square waves and spikes are ...
  • No UPS claims to protect hardware from that anomaly. Anyone can read specification numbers. What do most here do? Ignore all numbers. How many joules does that UPS claim to 'absorb'? Hundreds. A ...
  • Earth leakage protection is only for protecting human life. It does nothing to protect appliances. Effective power surge protection always answers this question. Where do hundreds of thousands of ...
