I'm not familiar with that style of fan, where does it go and what does it vent to? What would be the cause for the high current draw and the burned twist connector? Bad bearings in the fan? Seems if it's bad bearings, then that problem could raise its ugly head again sometime. That'd make me nervous. [scared]
Locally ridge vents, plain static vents (they look terrible) or large attic fans (24"-30" diameter) turning at a low rpm are popular.
[member=44099]Cheese[/member], the fan type I mentioned are sometimes called mushroom fans. Here is one example. There's a small motor inside the dome. I think the wiring got burned because whoever wired it in used an older type of wire nut that didn't have the spiral spring inside that really digs into the wire and holds the wires together. I suspect that over time, a high-resistance short developed and caused the heat that burned the wiring. All that got fixed this morning when I wired in the new fan. It's up there spinning merrily away, cooling the attic. (And I'm out of the attic, scrubbed, clean and smelling a whole lot better now.) [big grin]
