look up !
Denise, I went to yachtworld.com and looked up hunter 280's for sale, the interior pictures all show the electrical panel mounted on the ceiling of the cabin just above the table. If yours is not there maybe? 120 was an option? and it is not installed on your boat. but there should be a 12 v panel somewhere(it shows in the same place on the pictures) Or else maybe I'm not understanding what you are looking for. Hope this helps!
