What is the maximum ground resistance specified by manufacturers of sensitive electronic equipment for proper operation?

Manufacturers of sensitive electronic equipment typically specify a maximum ground resistance of 1 ohm to ensure the proper operation of the devices. This low resistance level is critical because it allows for effective grounding, which helps to dissipate any electrical surges or faults that could jeopardize the performance and safety of the equipment. A ground resistance of 1 ohm ensures that the path to the ground is sufficiently low-resistance, allowing for quicker fault current paths to minimize the risk of equipment damage and enhance protection against electrical shock.

This specification also aligns with the industry standards for grounding sensitive electronics, where the aim is to maintain operational integrity while minimizing risks associated with electrical disturbances. Higher resistance values could lead to inadequate grounding, increasing the chance of equipment malfunction or failure.
