Always use a voltage tester on the fixture wires even after turning off the breaker—live wires can exist due to wiring errors or double-switched circuits, and contact with 120V current during installation can be fatal. A Klein Tools Non-Contact Voltage Tester ($12-18) takes seconds to verify safety and eliminates guesswork.

TipKasa Team

Support the new fixture body with one hand or a temporary brace while connecting wires, since dangling from the ceiling box strains connections and creates poor wire nut seals that fail within months. Rushing this step accounts for the majority of fixture failures homeowners attribute to defective products.

ExperienceKasa Team

Hire a licensed electrician if the existing junction box is cracked, the wires show cloth insulation (indicating pre-1960s wiring), or if removing the old fixture reveals more than two cables entering the box—these situations suggest code violations that create fire hazards. The $150-300 diagnostic fee protects far more than the fixture itself. ---
