Setup and Installation
The TL104 Live End Current Limiter is designed for direct connection to a 120V, 60Hz power source and integration into a Satco track lighting system. An optional canopy plate (Satco SKUs TP212/TP213) may be used for direct junction box mounting.
- Power Disconnection: Before beginning any installation, ensure the main power supply to the circuit is turned OFF at the circuit breaker.
- Prepare Wiring: If using the knockout for direct electrical feed, remove the appropriate knockout. Connect the pre-wired leads from the current limiter to the building's electrical supply wires (black to live, white to neutral, green/bare to ground) according to local electrical codes. Secure connections with approved wire connectors.
- Mounting to Track: Align the live end connector with the end of the track section. Ensure the polarity is correct (usually indicated by markings on the track and connector).
- Secure Connection: Push the live end firmly into the track until it clicks into place. Tighten any securing screws on the connector to ensure a stable and continuous electrical connection.
- Optional Junction Box Mounting: If using an optional canopy plate for junction box mounting, follow the instructions provided with the canopy plate to secure the limiter to the junction box and then to the track.
- Final Check: Double-check all connections and ensure the unit is securely mounted.
- Restore Power: Once installation is complete and verified, restore power at the circuit breaker.

Operating Instructions
The Satco Nuvo TL104 Track Live End Current Limiter functions as a protective device within your track lighting system. Once properly installed and connected to power, it will automatically electrify the track and limit the total current draw to 5 Amps.
- Power On/Off: The unit features a rocker switch (ON/OFF) to control power to the track system. Toggle the switch to the 'ON' position to supply power to the track and 'OFF' to cut power.
- Current Limiting: The built-in resettable circuit breaker will automatically trip if the total current drawn by the track fixtures exceeds 5 Amps, protecting the system from overload.

Troubleshooting
If your track lighting system is not functioning as expected, refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to track lights. | 1. Power switch is OFF. 2. Circuit breaker tripped. 3. Loose electrical connections. | 1. Ensure the ON/OFF switch on the limiter is in the 'ON' position. 2. Reset the circuit breaker on the limiter (if applicable) or at the main panel. Reduce load if it trips again. 3. Disconnect power and check all wiring connections. Tighten as necessary. |
| Circuit breaker repeatedly trips. | Overload on the track system (total wattage exceeds 5 Amps). | Reduce the number or wattage of fixtures on the track. Ensure total current draw does not exceed 5 Amps (600 Watts at 120V). |
| Unit is warm to the touch. | Normal operation under load. | This can be normal. If it is excessively hot or emits a burning smell, immediately disconnect power and consult a qualified electrician. |
If troubleshooting steps do not resolve the issue, contact a qualified electrician or Satco customer support.
