Solid Grounding For Your Generator

Generator grounding errors can cause current flow in de-energized circuits. This can cause nuisance tripping of protective circuits, with costly and possibly lethal results. Most electricians and engineers work little with grounding generators, and they certainly have little time to research the

Aegis Shaft Grounding Rings protects bearings and electric motors from damaging shaft voltages caused by variable frequency drives (VFDs). The voltages emitted by VFDs find their way to ground typically through the motor’s bearing.

An electric switchboard is a device that directs electricity from one or more sources of supply to several smaller regions of usage. It is an assembly of one or more panels, each

Generator grounding errors can cause current flow in de-energized circuits. This can cause nuisance tripping of protective circuits, with costly and possibly lethal results.

Grounding refers to connecting an electrical circuit to a reference ground. In the case of a generator, the frame of the generator acts as the electrical circuit and a properly installed grounding rod acts as the reference ground.
