1. Safety Information

Important Safety Notice: Installation and servicing of this electrical equipment must be performed by qualified, licensed electricians in accordance with all applicable national and local electrical codes. Failure to do so can result in serious injury, death, or property damage.

Always disconnect power at the main service panel before working on or near the load center. Use appropriate personal protective equipment (PPE) including insulated gloves, safety glasses, and non-conductive tools.

For your safety, it is crucial to purchase only genuine, ABB-manufactured electrical products (inclusive of those branded GE or GE by ABB and now manufactured by ABB). Counterfeit and non-authentic products may fail to meet safety standards, putting you at risk. To ensure you receive safe, reliable products, check the product description and photos and verify that the product is described as an ABB, GE, or GE by ABB product and has labels with an ABB, GE, or GE by ABB logo. Please also check the product description to see if the product has been certified by third-party certification bodies such as UL, IC and/or Intertek.

3. Setup and Installation

Professional Installation Required: Due to the inherent dangers of working with high voltage electricity, the installation of the TM1615RCU load center must be performed by a qualified and licensed electrician. This manual provides general information and is not a substitute for professional expertise or adherence to local electrical codes.

3.1 Pre-Installation Checks:

• Verify that the load center specifications (voltage, amperage, number of spaces) match the requirements of the installation site.
• Ensure all necessary tools and materials are available, including appropriate wiring, conduit, and mounting hardware.
• Confirm that the installation location is suitable for an outdoor electrical enclosure, providing adequate clearance and protection from physical damage.

3.2 Mounting:

• Select a flat, stable, and accessible surface for mounting.
• Use appropriate fasteners to securely attach the load center to the mounting surface. Ensure the enclosure is level and plumb.

3.3 Wiring:

• All wiring must comply with the National Electrical Code (NEC) and local building codes.
• Connect the main service conductors to the main breaker terminals.
• Install branch circuit breakers into the designated slots and connect the load conductors.
• Properly connect neutral and ground conductors to their respective bus bars.
• Ensure all connections are tight and secure to prevent loose connections and potential hazards.

After wiring, replace the cover securely. Do not energize the system until all connections have been double-checked and the installation is complete and inspected by a qualified professional if required by local regulations.

4. Operating Instructions

The TM1615RCU load center is designed for straightforward operation once installed. Its primary function is to safely distribute electrical power to various circuits and provide overcurrent protection.

4.1 Circuit Breaker Function:

• Each circuit breaker protects a specific electrical circuit from overloads and short circuits.
• In normal operation, circuit breakers are in the "ON" position.
• If an overload or short circuit occurs, the breaker will automatically "trip" to the "OFF" or center position, interrupting power to that circuit.

4.2 Resetting a Tripped Circuit Breaker:

1. Identify the Cause: Before resetting, try to determine what caused the breaker to trip (e.g., too many appliances on one circuit, a faulty appliance). Address the issue if possible.
2. Turn OFF: Firmly push the tripped breaker's handle completely to the "OFF" position. You may hear a click.
3. Turn ON: Firmly push the breaker's handle to the "ON" position.
4. If the breaker immediately trips again, do not attempt to reset it repeatedly. There is likely a persistent electrical fault that requires professional attention.

4.3 Main Breaker Operation:

The 150A main breaker controls all power to the load center. To completely de-energize the entire panel, switch the main breaker to the "OFF" position. This should only be done by a qualified individual for maintenance or emergency purposes.

5. Maintenance

Regular inspection and maintenance can help ensure the longevity and safe operation of your load center. All maintenance procedures should be performed by a qualified electrician with the power disconnected.

5.1 Periodic Inspection (Annual):

• Visually inspect the exterior of the load center for any signs of damage, corrosion, or water ingress.
• With power off, open the cover and inspect for loose wires, discolored insulation (indicating overheating), or signs of rodent activity.
• Check that all circuit breakers are securely seated in their positions.
• Ensure all screws on terminals and bus bars are tight.

5.2 Cleaning:

• Keep the exterior of the load center clean and free of debris.
• If cleaning the interior, ensure power is completely off. Use a dry, soft brush or vacuum cleaner to remove dust and debris. Do not use liquids or abrasive cleaners.

Do not attempt to modify the load center or its internal components. Any modifications can compromise safety and void the warranty.

6. Troubleshooting

This section provides basic troubleshooting steps for common issues. For complex problems or if you are unsure, always consult a qualified electrician.

Always prioritize safety. If you are unsure about any electrical issue, do not attempt to fix it yourself. Contact a licensed electrician.
