Nothing happens. A hole is drilled through the joist and the wire is pulled through it.
250 to 300mm center to center
Under electrical code 368.56(B), flexible cords and cables can be attached to building surfaces. However, under electrical code 400.8, flexible cords and cables are not permitted to be dropped from a bar joist.

Drill a hole large enough and pull the cable through. The hole must be 1-1/2" from the edge of the joist to prevent nails or drywall screws from penetrating the cable. If the hole is less than this distance, a nail plate must be installed over the edge of the joist so when the wall covering is added, a screw or nail can't penetrate the wire. Any hole drilled through a joist must be no more than a fifth of the depth of the joist and should be as near as possible to the centre of the joist. Holes bigger than 30mm are not recommended without specifically designed additional strengthening to the joist.
Floor joist or ceiling joist? Floor joist have a board on the end all the way along the side of the building called a rim joist. Like the cross bar on the top of a T. Ceiling joist are nailed down into the top plate of the wall and to the rafters where possible.
A joist is a beam, a supporting structure in a building. The roof joist was riddled with dry rot and had to be replaced.
To reinforce a joist hole using a joist hole reinforcer, you can insert the reinforcer into the hole and secure it in place using screws or nails. This will help strengthen the joist and prevent further damage.
A rim joist, also known as a band joist, is the joist that runs along the perimeter of a floor system, providing support for the ends of the floor joists and acting as a barrier to airflow and insulation. In contrast, an end joist is a specific joist located at the end of a span, connecting two adjacent joists or providing additional support at the end of a row. While both serve structural roles, the rim joist is integral to the overall framing of the building, whereas the end joist is focused on connecting and supporting individual joists.
it depen on the size of the joist
To sister a joist for structural reinforcement, you will need to attach a new joist next to the existing one to provide additional support. This can be done by securing the new joist with nails or screws along the length of the existing joist. Make sure the new joist is the same size and type of wood as the existing one for proper reinforcement.
The floor joist system that requires solid blocking or diagonal bridging is the conventional wood joist system. This system uses wooden joists spaced apart to support a floor, and solid blocking or diagonal bridging helps prevent lateral movement, adds stiffness, and distributes loads more evenly. This reinforcement is essential in maintaining structural integrity and minimizing vibrations in the flooring.
The key difference between a rim joist and a band joist in a building's construction is their location and function. A rim joist is located at the edge of a floor system and provides support for the floor joists, while a band joist runs horizontally around the perimeter of a building and helps to distribute the load of the structure.
