Thermal Impressions: Low Emissivity Electrical Lug Inspection.

A often overlooked predictive maintenence job is he inspection of electrical lugs. In this example I will inspect the lugs within my outback fm80 mppt charge controller.
Removing the Access Panel.


Just 3 screws and the panel is off. Now the insides are visible for inspection.
The Camera.

My beloved seek thermal xr camera will be used to perform the inspection.
The Results.


OK here is a side by side visual and infrared view. Notice the lugs are shiny aluminum. This is not good for thermography. Instead I pay attention to the cables immediately at each lug. As per the thermal image there are no hot spots and all seem within acceptable temperatures.
Using a thermal camera it is very easy to perform electrical inspections.
