elgato Posted September 21, 2016 Report Posted September 21, 2016 I feel like this may be a dumb question, but double taps are never allowed on main lugs are they ? even for surge protectors ?
Marc Posted September 22, 2016 Report Posted September 22, 2016 Ideally, the listing of the lug would have that info but I don't recall ever seeing a main lug on a panel that was listed for more than one conductor except for the kind that has that little setscrew lug on the side of it to accommodate taps. I wish I had a photo. Marc

They're allowed on some lugs, but usually with conductors of similar or close-to-similar sizes. (Is "close-to-similar" redundant? ) Click to Enlarge 47.06 KB Click to Enlarge 44.95 KB
fqp25 Posted January 5, 2017 Report Posted January 5, 2017 Would this be considered "Close to Similar"? Three conductors and one significantly smaller than the other two. Click to Enlarge 74.54 KB
Charlie R Posted January 5, 2017 Report Posted January 5, 2017 All of the surge protectors I have seen are to be installed on a separate double pole breaker by the manufacture's installation instructions. I am not saying that all are like that, just all that I have seen.
