A:AnswerAfter reading a few answers I'm confused both lights on great someone said if both were green I didn't see anything if one was red my surge red light, ground green light if lights red is that good or only green or does it matter on color as long as they are both lit
A:AnswerIf less than 30 feet of wiring are between the surge protector and electrical panel, the surge protector is not able to effectively protect against a surge.
A:AnswerI think they are referring to your breaker box or fuse panel. I don't understand the 30'. I have surge protectors and other electric cables within 6' of my breaker box and have no issues.
