What is the minimum amount of boom leakage current that can leave track burns inside the boom?

The minimum amount of boom leakage current that can leave track burns inside the boom is 1 mA. At this level, the current can generate enough heat to cause a noticeable burn mark typically found where the electrical current has passed through the material. This occurs because 1 mA of current has the potential to create sufficient thermal effects due to resistance in the boom's material, leading to localized heating and potential damage as evidenced by track burns.

Understanding the significance of this current threshold is essential for maintenance and safety in electrical systems, especially in contexts where overheating could lead to failures or hazards. Low levels of current, such as those below 1 mA, generally do not produce heat sufficient to cause damage, which is why the specified threshold is carefully noted as a minimum.
