What is a common cause of arc flashes when removing electrical panel fronts?

Removing electrical panel fronts can pose significant risks, and understanding common causes of arc flashes is essential for safety. In this case, using incorrect fasteners during the installation or removal of panel fronts can lead to a situation where electrical components are inadvertently manipulated, creating the potential for an arc flash.

If fasteners are not suitable for the application, they may not secure the panel properly, leading to improper alignment or conductive parts coming into contact with each other. This misalignment can create conditions that facilitate an arc flash due to short circuits, particularly if there is residual energy or charge in the panel.

The other options, while related to electrical safety, do not specifically address the direct impact of fasteners during the removal of panel fronts, making the issue of using incorrect fasteners a primary concern in this context. Properly chosen fasteners ensure the panel is safely secured and reduces the risk of electrical hazards when performing maintenance or inspections.
