I need to run wiring for my home entertainment setup thru an exterior wall.
This is obviously a load bearing wall and I assume that it's 2x6 beams, I
am not sure what the code is in NJ. This is the first floor of a two
story house and I wood need to drill holes in approximately 3 beems to go
accross a four foot span. I would appreciate any advice on if I can drill
or notch the beams and to what extent. Also these beams are above a
window, so I would also have a header beam to contend with. I appreciate
all advice.

Thanks;
Marty
