Greg,
When I see a BA/FA transformer it is either in a duplex receptacle that is over 6' or higher. (no GFI required). I have seen them in single receptacles. Then the installer usually tie warps the trans to the box.
Would you allow this, a duplex receptacle with the phase leg strap snipped so that the top half of the duplex is dead, but the bottom half is live. This way the installer can still use the 6-32 screw to hold the trans in place. Also you should make the installer paint the top half black or something like write DEAD on the top half.
