I have a Tripp Lite AVBar10 that shows two green LED on the outside ("protected" and "line OK") and a red LED in the middle ("ground").

I went to Lowes and got an outlet tester, and all the circuits checked out okay. When testing the AVBAR10, it reads okay in all circuits on the strip. I spoke with Tripp Lite and they sent me a replacement, but it reads the same.

    According to the manual on the Tripp Lite site the ground LED should be lit if it is properly grounded. Why they make it red I don't know. – Craig Oct 8 '13 at 19:51
  • @Craig That sounds like the answer (RTFM). Please consider adding it as an answer, instead of a comment. – Tester101 Oct 9 '13 at 10:31
  • Thank you. Regarding "RTFM" -- yeah I did, and I called them BUT nowhere does it say that two LEDS will glow GREEN and one LED wioll glow RED when everything is working. Have you ever heard of a RED LED meaning things are AOK? – Ecks Oct 9 '13 at 13:13

Sounds like this is "functioning to spec". I think that is just how this surge suppressor works.

Why is it red? I know I have had basic suppressors in the past that only had a red ground light (no "line OK" or "protected" lights). Perhaps they think people expect the ground light to be red.
