Ground fault detection feedthrough is effective for a maximum of
two serially connected (point-to-point) repeaters. Therefore, a maximum
of five repeaters can be connected in series when ground fault detection is
required. Figure 15 shows how the ground fault detection feedthrough
switches must be arranged in order to achieve this maximum
configuration.
