I have one left on shelf, these can be hard to come by. DO NOT compare this to what Lowes or HD sells, their units DO NOT have the Feed Through Lugs. You definitely want the meter with FEED THROUGH LUGS.
These are also called CSED's in the trade. Combination Service Entrance Device
Also see my electrical ads for tri-state area under skilled trade section. I do pro electrical installs of all kinds over the tri-state area.
