Which type of equipment is NOT typically grounded with an equipment grounding conductor?

Rechargeable batteries are typically not grounded with an equipment grounding conductor because they are not considered electrical equipment that poses a shock hazard in the same way that other options do. Grounding is primarily implemented for devices that have a metal enclosure or are otherwise conductive, helping to ensure that any fault current is safely diverted to the ground.

Portable tools and fixed machinery often feature metal casings and components that could become energized due to faults, making grounding essential for safety. Low-voltage lighting may also require grounding depending on installation and use. However, rechargeable batteries usually operate at lower voltages and are designed to prevent users from coming into contact with live electrical parts. They often feature insulated enclosures that minimize risk, which negates the need for a dedicated equipment grounding conductor. Therefore, unlike other equipment that requires grounding to ensure safety and compliance with electrical regulations, rechargeable batteries do not typically fall into this category.
