The wire to the
left of this main electrical shutoff switch is
the system ground wire. It is supposed to be
connected to the incoming water pipe for the
house. This should be corrected immediately for
safety sake so that a short to ground in the
system will blow a fuse or trip a breaker
instead of energizing the device box or the
housing of the device that is connected to it.
The correction should be done by a qualified
electrician. |
