Proper installation begins with selecting a junction box rated for bathroom use—look for UL or equivalent certification. Ensure the box is mounted away from direct water splashes and secured with appropriate wall anchors. Always follow local electrical codes: wire connections must be tight, insulated, and taped per regulations. Use wire nuts rated for low-voltage circuits and test connections with a multimeter before energizing. For professional results, consult a licensed electrician when integrating with complex vanity lighting systems.
