Great calls wirewiz
I would also call 99 or 02 NEC Section 300-14. last sentence for lower left.
" .... Where the opening to an outlet, junction, or switch point is less than 200 mm (8 in.) in any dimension, each conductor shall be long enough to extend at least 75 mm (3 in.) outside the opening."
What else?
Does anyone have any additional references?
