Moderator can copy these pictures to photo discussion section if he likes. Found this was quickest way for me to post pictures. This wiring is not exposed. This will be covered with dry wall. For exposed wiring I use conduit big enough and also take off outer jacket of romex from six inch in conduit. Please inspect and tell if some thing is wrong.
