Frame Ground Connection

WARNING: Be sure the system is properly grounded before applying power. Do not apply AC power
before you ensure that grounds are connected. Electrical shock can cause serious or fatal
injury. NEC requires that the frame and exposed conductive surfaces (metal parts) be
connected to an approved earth ground. Local codes may also require proper grounding of
generator systems.
The NEC requires that the frame and exposed metal surfaces be at local ground reference
potential to avoid electrical shock hazard. A local ground reference may require a driven earth
ground conductor at the generator installation site. Make the ground connection as shown in
Figure 3-3. Use the appropriate size wire (normally 6 AWG) as required by NEC and local
codes. The local reference ground is normally a copper clad earth ground rod driven into the
earth at least 8 feet.
