Finding Electrical Problems Before They Spark Fires;Thermal Cameras: The Electrician’s Secret Weapon

Article NEWS 559

Shocking Truth:
Over 25% of electrical fires start from simple connection issues that thermal cameras can spot weeks in advance.

Real-World Example:
During a factory maintenance check, a thermal camera reveals a circuit breaker glowing at 75°C (normal <35°C). Closer inspection shows a corroded connection causing overheating, with the plastic casing warping. Replacing the faulty component immediately avoids a fire risk—thermal cameras detect invisible heat signatures that signal impending electrical failures.

How It Works:

  1. Scan panels/switches with thermal imaging small cameras

  2. Hot connections show as bright yellow/white

  3. Hot spots may indicate broken wires

3 Most Common Finds:
⚡ Loose wires (50% hotter than normal)
⚡ Overloaded circuits (whole panel "glowing")
⚡ Failing breakers (one side hotter)

Budget Tip:
While infrared imaging camera price starts around $2,000, many insurance companies offer discounts for using this prevention tech.
