Does anyone have specs (including joule rating) and/or an opinion on the discontinued L4400-P 6-Outlet Plug-in Surge Protection Device? It's similar to the present 3500-P, 4900-P and 5100-P SPDs. Several years ago the JEA (Jacksonville Florida Electric Authority) had Leviton make a large number of them with their logo and they offered them to their customers along with a 50240-FAA Meter Socket Surge Arrester Adapter. Jacksonville/Duval County is the lightning strike capitol of the world and I assume somebody knew what they were doing. However, they apparently didn't sell very well (JEA has big PR problems) and are now on the secondary market long with the 50240-FAA at bargain prices. Thanks.
