According to the general rule, to what side should a grounding connection not be made for service disconnecting means?

The grounding connection for service disconnecting means is generally not made on the load side. This is because the load side is where electrical devices and circuits operate, and grounding on this side can create safety hazards and electrical noise that may affect the performance of the equipment.

When grounding is performed on the supply side or neutral side, it ensures that any fault currents are properly directed to ground, reducing the risk of electrical shock and equipment damage. The neutral side provides a return path for electricity and is bonded to ground at the main service panel, creating a safer and more stable electrical system.

By not making a grounding connection on the load side, you ensure that the ground reference is consistent and doesn't interfere with the operation of devices or create potential safety risks in circuits that are energized. This is part of the safety practices in electrical installations to prevent equipment malfunction and ensure the safety of individuals working with or near electrical systems.
