Possible Causes of Arc-faults with Juno LED IC 20 Recessed Lights



1. Overcurrent Protection Devices (OCPDs)

Ensure the arc-fault breakers (AFCs) are rated for the correct amperage and type of load (lighting). Check if the AFCs are compatible with LED lighting. Some older models may not be compatible and can cause nuisance tripping.

2. Faulty Wiring

Inspect the wiring connections to the lights and make sure they are tight and secure. Loose or damaged wires can create arcing conditions.

3. Poor Contact

Verify that the light fixtures are making good contact with the junction box. Use anti-oxidant paste on the wire connections to prevent corrosion and ensure proper contact.

4. Electrical Interference

Check for sources of electrical interference nearby, such as power tools, motors, or other heavy loads. These devices can create transients and surges that can trigger AFCs.

5. Compatibility Issues

Ensure that the Juno LED IC 20 lights are compatible with the AFCs installed. Some AFCs may not be compatible with certain types of LED drivers or fixtures.

6. Overloading

Verify that the AFCs are not overloaded with too many lights or other loads on the circuit. Each AFC has a maximum amperage capacity. Exceeding this capacity can cause arc-faults.

7. Fixture Modification

Check if any modifications have been made to the light fixtures, such as drilling holes in the can or cutting wires. These modifications can compromise the integrity of the fixture and create arcing hazards.

Troubleshooting Steps



Replace the AFCs

Try replacing the AFCs with new ones to rule out a malfunctioning breaker.

Check Wiring Connections

Inspect all wire connections and tighten them securely.

Install Anti-oxidant Paste

Apply anti-oxidant paste to all wire connections to prevent corrosion and ensure proper contact.

Eliminate Interference

Remove any sources of electrical interference nearby and see if the issue persists.

Check Compatibility

Verify that the lights and AFCs are compatible by consulting the manufacturers' specifications.

Reduce Load

Remove some lights or other loads from the circuit to reduce the load on the AFC.*
