Following the bonding of telecom infrastructure components, the entire system must be bonded to the building's main ground, which is sometimes also referred to as a grounding electrode system. References
A ground connection that is missing or of inadequate capacity may not provide the protective functions as intended during a fault in the connected equipment. Extra connections between ground and circuit neutral may result in circulating current in the ground path, stray current introduced in the earth or in a structure, and stray voltage.
Insulated bearings eliminate the path to ground through the bearing for current to flow. However, installing insulated bearings does not eliminate the shaft voltage, which will still find the lowest impedance path to ground. This can potentially cause a problem if the path happens to be through the driven load or through some other component.
The ground loop still exists, but the two sides of the loop are close together, so stray magnetic fields induce equal currents in both sides, which cancel out. Break in the shield Create a break in the signal cable shield conductor. [5] The break should be at the load end. This is often called ground lifting. It is the simplest solution; it ...
The "local" earth/ground electrode provides "system grounding" [13] at each building where it is installed. The "Grounded" current carrying conductor is the system "neutral". Australian and New Zealand standards use a modified protective multiple earthing (PME [ 14 ] ) system called multiple earthed neutral (MEN).

Grounding at one end only to prevent groundloops has gone to far into EE designer folklore, so much they will ground coax signal cable shields at one end only with distastrous results. Grounding at both ends is the only way to intercept magnetic fields and reduce their coupling to the interconnecting wires.
The ground lift switch eliminates unwanted hum and buzz by interrupting the ground loops between equipment, preventing current flow along the cable shield between two devices. The switch disconnects pin 1 on the XLR jack, which is connected to the braid or foil shield in the cable and acts as the ground point of the circuit.
