used to connect the ground termi-
nal of the Generator to a grounding
rod. A wire that is too thin may not
provide sufcient electrical current
carrying capacity to be an adequate
ground path.
The other end of the ground wire•
must be securely fastened to an
approved ground source. Refer to
local regulations for ground source
information. If unsure of regulations
or procedures, obtain assistance
from a licensed or certied electri-
cian.
