With the electrical box securely in place, run the new electrical wire (Romex) from the box. First, install a strain relief clamp into one of the knockouts on the electrical box. Feed the Romex wire through this clamp and into the box, ensuring enough length extends into the box for connections. Tighten the strain relief clamp to secure the wire. Next, route the Romex wire along the ceiling joists towards the wall where the light switch will be located. Use wire staples or fasteners to secure the Romex to the framing members within several inches of the electrical box and at regular intervals along its path, as required by electrical codes, to prevent it from sagging or being damaged.
