I'm using a WE 620A2 Panel connected to a 79B5 power plant. I can't find the maximum number of lamps that a 400 series KTU can support, I'm guessing between 15 and 20 (all cable runs < 30 ft). I also found a BSP reference to a 469 Lamp Extender KTU that also plugs into the 620 panel, providing 20 lamps per ckt. Of course, I can't find any on eBay! Closest is a Melco KT-631 Lamp Extender. Anyone have any advise on either? Regards, Jim
