D, if it is a three-phase generator, then pay attention to the zero line of the best connected and mine company, and to ensure oil machine load of three phase 8, the following work on the ground and protect the ground description is correct (A , C, D) the same as A, ground work load line selection and maximum diameter. B, to protect ground and work the same ground. C, when the AC input line diameter is less than 16 mm2, protect ground and AC input with the same wire diameter; when the AC input line diameter greater than 35 mm2, you can choose half the diameter of the phase as a protective ground in diameter. D, when between 16 mm2 and 35 mm2 AC input line diameter, protect ground diameter chosen 16 mm2.
