In this regard, can you put a junction box in the ceiling?

Junction boxes must be installed where they are always accessible; never install a junction box in a concealed wall or ceiling space where the box cannot be accessed in the future. Junction boxes also must be covered with solid covers with no holes.

Likewise, is it OK to use junction boxes? Never connect wires outside of electrical boxes.

Where connections aren't contained in an electrical box, install a box and reconnect the wires inside it.
