greyboy39 Posted May 17, 2017 Report Share Posted May 17, 2017 Saw a double tapped ground lug today, ground feeder to 60 amp garage subpanel. Is this condition ever allowed. The house is owned by an electrician and this is the only reason Im questioning if there are allowances for this condition. Quote Link to comment Share on other sites More sharing options...
Chad Fabry Posted May 17, 2017 Report Share Posted May 17, 2017 If that panel is the service equipment and the terminal is rated for two wires (it's probably not) then it's OK. Quote Link to comment Share on other sites More sharing options...
greyboy39 Posted May 17, 2017 Author Report Share Posted May 17, 2017 It is the main panel. Is there anyway to tell if the terminal is rated for two wires? Ive read that snowman shaped terminals/lugs are designated for two wire installations. Quote Link to comment Share on other sites More sharing options...

adarty Posted May 21, 2017 Report Share Posted May 21, 2017 As Jim Katen mentioned, the lug will bear a stamp giving number of conductors and size of acceptable conductors. Aluminum SE and a copper conductor under the same screw at that lug? I thinks that is just asking for trouble... Quote Link to comment Share on other sites More sharing options...
