Grounding Earth ground 1. Earth ground must be capable of conducting enough cur-
rent to blow the 20A fuse (or breaker) in the event of an
internal short circuit.
2. Use wide straps or brackets to provide minimum length,
maximum surface area ground conductors. If a leadwire
must be used, use 14 AWG copper wire.
3. Make sure that mechanically tightened joints along the
ground path are free of nonconductive coatings and pro-
tected against corrosion on mating surfaces.
Grounding Signal ground Use the shield of the signal wire to ground the device to the
signal ground terminals [3(c)] of each device. Connect the
shield at both ends of the chain to earth ground.
