We are in the process of building our house and have run into a snag that we are unsure about. We have electric wired in our carport and not sure how to connect it to the house- keeping in code. Can we just run it through the outside walldown near the floor/ground or is it better to run it through the joist into the loft of the house?

Not seeing the actual situation it is impossible to tell from here.

Who is doing the wiring? Don't they know how to do this?

We are building it ourselves. We figured most of it out and I had an electrician come through and made sure it all looked good and would pass code. Now onto the heating and AC duct work...
