We're prepping the spec for electric rough and up to this weekend, always figured we would use Romex or other plastic sheathed cable. But on one of the home improvement shows, a NJ house that had been gutted by an electric fire was being rewired with BX.

Are there any real advantages to using armored cable in new house construction? Or, to save expense, are there select areas (for example, in attic spaces that are accessible for storage) where it should be used?

Or are there other plastic-sheathed wire upgrades? I've never understoof 70º versus 90º wire and wonder if there's an upgrade to basic wiring that makes good sense?

We are already planning to spec nothing less than 12ga, but would appreciate the upgrades to the basic wiring that make the most sense.

Thanks for the feedback! --Mark
