I need to run some wires from outside the house to inside the house. Outside the house the wire is in either 1/2-in or 3/4-in rigid conduit. Whats the norm for getting the wires inside the house? I was thinking of poking a hole thru the wall and sticking the conduit thru, then seal around it with caulking. Not sure how to poke that big of a hole in stucco; with a big masonry drill bit?!?
