WHY DON’T WE SPECIFY JOULES?
The Joule rating does not provide an accurate indication of the robustness of a surge
suppressor. The Joule rating is energy over time and it is very easy to artificially inflate
the Joule rating by changing the time base. The Institute of Electrical and Electronics
Engineers (IEEE), as well as the National Electrical Manufacturers Association (NEMA)
both warn against using Joules to compare surge suppressors.
A much better indication of the robustness of a surge suppressor is the Nominal
Discharge Current (I
n
). The Nominal Discharge Current is a rating of the current surge
current the surge suppressor can handle for 15 surges and still remain functional. This
rating is independently verified by Underwriters Laboratories (UL) and the rating is
required to be marked on the surge suppressor.
In fact, UL requires that the surge suppressor must have an I
n
rating of 3kA or it is not
suitable for installation closer than 30 feet [10m] from the service entrance. All of our
surge suppressors have an I
n
rating of 3kA and can be used anywhere in the building.
When comparing surge suppressors, don’t be fooled by the Joule game. Look for an I
n
rating of 3kA to be sure you are getting the best in surge suppression.
