Should I use metal or plastic electrical boxes?

You should not use metal-sheathed or "BX"wiring with plastic electrical boxes. The reasoning issimple -- with armored cable, the box itself provides groundconductor continuity. For exposed or shop wiring, metalboxes are probably better. Metal receptacle coversmust be grounded, even on plastic boxes.
