Installation

Site Preparation

This involves verifying the designated location for the LT panel meets safety and accessibility requirements. It may include checking for proper ventilation, grounding, and cable routing paths.



Panel Mounting

The LT panel is securely mounted on a designated wall or structure, ensuring stability and proper alignment.



Cable Connections

All power and control cables are meticulously connected to the appropriate terminals within the panel, ensuring secure and proper polarity connections. Terminals are tightened to recommended torque specifications.



Grounding

Proper grounding is established to ensure safety and prevent electrical faults. This involves connecting the panel's grounding lug to the designated grounding system.

Commissioning

Pre-energization Checks

Once installation is complete, technicians perform a thorough inspection to verify all connections are tight, there's no loose debris within the panel, and all components are properly installed.



Energization

The LT panel is carefully energized following a specific procedure. Voltage and current readings are monitored to ensure everything functions as expected.



Protection System Testing

Trip settings of circuit breakers and other protective devices are verified to ensure they operate according to specifications. This may involve simulating overload or short circuit conditions in a controlled manner.



Label Verification

Technicians ensure all labels within the panel are clear, accurate, and match the connected circuits for ease of future maintenance and troubleshooting.

Troubleshooting

Problem Identification

In case of an LT panel malfunction (e.g., tripped breaker, power outage on a specific circuit), technicians use their expertise and diagnostic tools to pinpoint the root cause of the issue. This may involve analyzing log data (if available), inspecting components for signs of overheating or damage, and using multimeters to measure voltage and current flow.



Safety Measures

Safety is paramount during troubleshooting. Technicians will follow proper lockout/tagout procedures to isolate the panel before working on it.



Documentation

A detailed report is generated outlining the troubleshooting process, identified problems, corrective actions taken, and any recommendations for future maintenance or preventive measures.
