Is the UL label an indication of a quality product?

Surge suppressors should perform to a specific standard (UL 1449). It is important that the surge suppressor is “listed” as performing to this standard. Avoid suppressors with labels worded like:

  • Tested to UL 1449
  • UL Classified
  • Tested to IEEE C62.41
  • Meets UL 1449
  • UL Recognized
  • Temporary Power Tap

Many manufacturers misrepresent their products. Some claim a UL listing for their products if they use a single UL listed component such as the power cord. Other products have never been tested as anything more than a temporary power tap, UL’s term for an extension cord. Many claim that they meet standards or that it has passed UL standards, when in fact, they have never been tested by UL.
