Grounding
Outlet
If outlet is not grounded,
install a copper wire (at least 14
gauge) from the outlet box, as shown in Figure 4, to a metal
cold water pipe. Use ground clamp on pipe.
IMPORTANT:
The cold water pipe you use as a ground
must have metal continuity to electrical ground. If continuity
is interrupted
by plastic, rubber, or other electrical insula-
tors; such as hoses, fittings, washers
or gaskets (including
water meter or pump), a metal bypass must be used. Any
electrically insulated connector
should be jumped (as shown
in Figure 5), with a length of No. 4 wire clamped
securely
at both ends.
