WebIn such cases a single-point ground may be needed as well as the multipoint ground required to control high-frequency interference. A hybrid ground with a capacitor termination at one end, typically 0.010.1 µF, and a hard termination at the other end can provide an open circuit at audio frequencies and a short circuit at radio frequencies ... WebFor lines or equipment operating at 600 volts or less, the employer may permit the employee to use insulating equipment other than a live-line tool if the employer ensures that the line or equipment is not energized at the time the ground is connected or if the employer can demonstrate that each employee is protected from hazards that may develop … Web4.152 – grounding.
