1. Introduction
This manual provides essential information for the safe and correct installation, operation, and maintenance of the Schneider Electric AL800SN 1000-Amp Neutral Assembly. Please read this manual thoroughly before proceeding with any installation or service to ensure proper function and safety.
1.1 Safety Information
- All electrical work must be performed by qualified personnel in accordance with national and local electrical codes and regulations.
- Always disconnect power before installing, servicing, or removing the neutral assembly.
- Use appropriate personal protective equipment (PPE) when working with electrical components.
- Ensure all connections are properly torqued to prevent overheating and potential hazards.
2. Product Overview
The Schneider Electric AL800SN is a 1000-Amp neutral assembly designed for use in electrical distribution systems. It provides a robust and reliable connection point for neutral conductors, facilitating safe and efficient power distribution.

3. Setup and Installation
Follow these steps for proper installation of the AL800SN Neutral Assembly:
- Preparation: Ensure all power to the installation area is disconnected and verified as off. Gather all necessary tools, including a 1/4 inch hex drive for the binding screws.
- Mounting: Securely mount the neutral assembly within the electrical enclosure using appropriate fasteners. Ensure the mounting surface is stable and capable of supporting the assembly and connected conductors.
- Wire Connection (Neutral):
- Strip the insulation from the neutral conductors to the appropriate length.
- Insert the neutral wires (sizes 30-500 kcmil Cu-Al) into the main binding screw terminals.
- Tighten the binding screws using a 1/4 inch hex drive to a torque of 300 lb-in. Verify that each wire is securely seated and cannot be pulled out.
- Wire Connection (Ground):
- Strip the insulation from the ground conductors.
- Insert the ground wires (sizes 6-250 kcmil Cu-Al) into the designated ground terminals.
- Tighten the ground terminal screws using a 1/4 inch hex drive to a torque of 275 lb-in. Verify secure connection.
- Final Inspection: Double-check all connections for tightness and proper wire seating. Ensure no loose strands are present. Confirm that the assembly is free from any physical damage.
4. Operating Principles
The AL800SN Neutral Assembly functions as a common connection point for the neutral conductors within an electrical system. It provides a safe and low-resistance path for return current under normal operating conditions. Proper installation ensures the integrity of the neutral path, which is critical for system stability and safety.
5. Maintenance
Regular maintenance helps ensure the longevity and safe operation of the neutral assembly.
- Periodic Inspection: Annually inspect the neutral assembly for signs of wear, corrosion, discoloration, or loose connections.
- Cleaning: If dust or debris accumulates, disconnect power and carefully clean the assembly using a dry, non-conductive brush or compressed air. Do not use liquid cleaners.
- Re-torque Connections: Periodically re-check the torque of all binding and ground screws, especially after initial installation and during routine maintenance, to ensure they remain at the specified values (300 lb-in for neutral, 275 lb-in for ground).
- Damage Assessment: If any damage is observed, such as cracks, severe corrosion, or deformation, the assembly should be replaced immediately by qualified personnel.
6. Troubleshooting
Should issues arise, consider the following:
- Overheating: If the neutral assembly or connected conductors show signs of overheating (discoloration, melting insulation), immediately disconnect power. This often indicates loose connections, improper wire sizing, or excessive current. Re-torque connections and verify load calculations.
- Intermittent Power: Loose neutral connections can lead to intermittent power issues or voltage fluctuations. Inspect and re-torque all connections.
- Physical Damage: Any physical damage to the assembly can compromise its integrity and safety. Replace damaged components promptly.
For complex issues or if you are unsure about any troubleshooting steps, contact a qualified electrician or Schneider Electric technical support.
