Grounded systems are the most common type of system installed in residential and commercial settings. Grounded systems involve grounding a circuit to the earth. This is accomplished by connecting a ground wire to a protected grounding electrode system at the point of service.

Balanced-to-ground systems are very similar to grounded systems, but they involve two ground wires instead of one. The two ground wires are connected to the neutral side of the panel at the point of service. They are then routed to ground rods installed in the earth. The rods are connected to the ground to provide better protection against lightning strikes and other disturbances.

The primary benefit of balanced-to-ground systems is that they provide more protection than grounded systems. The two ground wires enhance the integrity of the system, making it less vulnerable to power surges and “noise” on the line. This is especially important in industrial settings, where large amounts of power are used and voltage fluctuations are common.

Balanced-to-ground systems are not recommended for residences or commercial settings unless there is a specific need for improved protection. The cost of installation is higher than with a grounded system, and the complexity of the installation can be difficult for the average homeowner or business to manage. In addition, it is important to have a qualified electrician install the system to ensure it is done correctly.
