[RE-wrenches] Surge protector update?

[Exeltech]

Jay,

Installing a part in a "factory" doesn't make a product "ok".  Would be nice, but it doesn't work that way...


I use "UL" here .. but it can be any Nationally Recognized Testing Lab (ETL, CSA, UL, etc....)

Any UL "Listed" product, or any UL "Recognized" part or sub-assembly must either use components that in of themselves are also Listed and/or Recognized to specific UL Standards, or prove during UL testing of the final product that any uncertified component(s) used within the product being tested fully meet the applicable Standard(s) for such parts.

Failing that, the unit in question won't qualify for Listing/Recognition, and no UL (or equivalent lab) certification will be issued for that product by any Nationally Recognized Testing Lab.  UL. ETL. CSA.  etc...

Just as all grounding components in a system must meet code, which requires the use of agency certified parts .. use of a non-certified part as a protective element is likely to get the system red-tagged, as Holt pointed out earlier in this thread.

For notes .. not everyone is aware that "agency certification" refers to UL, ETL, CSA, and a number of other OSHA-certified Nationally Recognized Testing Labs.  Product approvals from any of these labs are equivalent, though they're not always treated as such by AHJs or others who aren't well informed on this issue.  Thankfully, the "It must be UL" attitude by AHJs and others is steadily fading as an issue.  Not gone - but fading...
