How does conduit start?
In the case of an indoor wire run, the conduit will start as soon as the wire exits the home. A hole is usually drilled through the foundation and then an LB conduit body is used as an attachment point for the conduit. From the LB the rest of the conduit is trenched to the disconnect or strapped along the bottom side of the home if trenching is not an option.
