Power Electric Wires Thermal Scan

Power Distribution Wires and Terminals

1.) Loose or oxidized terminal connections 2.) Uneven torque at terminal screws 3.) Load imbalance across phases 4.) Undersized conductor or faulty lug/crimp

1.) Overheating at contact points 2.) No known tripped breakers, but load imbalance or resistance may be developing 3.) No audible buzzing or burning smell reported 4.) Risk of insulation degradation due to temperature rise

Significant heat signatures observed at terminal blocks L1, L2, and L3, as well as neutral (N) and PE (ground). Colors range from yellow-red to white at contact points.

1.) Use thermal scanner at different loads to compare trends 2.) Conduct torque checks at terminal blocks 3.) Use clamp meter to validate current load per phase 4.) Visually inspect for oxidation, discoloration, or arc marks

1.) Immediately retorque and re-terminate connections (lockout/tagout required) 2.) Clean contact surfaces if oxidation is present 3.) Rebalance loads if asymmetry is confirmed 4.) Log this panel in thermal scan route for monthly trending
