nothing personal to the original poster, but why would
anyone use plastic boxes????? I know the obvious
answer is cost, but seriously.......a few pennies for the
quality and strength of steel?????

1. Cost -- difference is about a dollar and a half per box, not "a few
pennies".
2. Ease of installation:
a) boxes don't have to be grounded
b) cables don't have to be clamped to box, as long as they're secured to
framing within (IIRC) 6" of the box
c) because cables don't have to be clamped to box, there's no deduction from
the rated cubic capacity of the box for cable clamps
d) light weight means it's easier to lug a full carton of boxes
