I am remodeling a garage that has a recessed electrical panel. I have removed the romex and want to put in emt conduit. Since I dont have the flexibility in emt the easiest way to put it in is to cut out part of the header about 12 inches long and 1 inch deep. The header is made of 2 2x4's. If I reinforce the adjacent studs by doubling them up with another 2x4 is this enough to pass inspection?
