Does anyone know what the life expancy of the sheathing and insulation of standard NM cable when exposed to the ultra violet rays of the sun. Cable intalled in an unfinished interior space where the sun can come through a window and strike the cable. Obviously this will vary depending on location, orientan of the window and anything else affecting exposure. But does anyone have a rough idea how long it will last?
