The way I understand the information that has been posted so far is that the
grounding rod(s) should be connected to the main breaker box. I live in
South Arkansas and here the electrical services I have seen have a grounding
round under the electrical meter. For a 200amp service a bare #4 wire is
run from the meter can to the grounding rod. The service into the breaker
box is only three 00 wires. Two hots and a neutral. Other services such as
cable and phone run wires usually around #10 and clamp on to the bare ground
wire. Is this not right. Has been several months since I helped do one,
but in the past all have pasted inspection.
The power co. has the final say about whether they will hook up power to a
building. The electric service must be built to _their_ specifications.
There is usually collaboration between the power co.'s requirements and the
local electrical inspection authority (AHJ....Authority Having
Jurisdiction).......IOW, the local electrical inspector will not pass
something that he know's won't be acceptable to the power co. For example,
entire the State of Florida is under the 1999 NEC. The 1999 NEC, or 2002
for that matter, does not require that a lightning protector be installed at
the electric service.......BUT the power co.(TECO) _does_require
one.......and will _not_ hook up a service that doesn't have one. Once a
homeowner or electrical contractor calls in an inspection to the AHJ, after
it passes that inspection, the AHJ calls it in to the power co. The power
co. then sends out _their_ inspector. If it passes their inspection, _only_
then will the service be hooked up. Most people don't see the power co.
inspector, as they are usually in and out before anyone knows they were
there (it's already been scrutinized by the AHJ and they are just confirming
Same goes for the GEC (Grounding Electrode Conductor) in my area......the
_power co._ requires that the GEC come out of the meter. As far as the
discussion going on in here, there isn't much difference where the GEC is
connected (either at the meter or the main panel), the _principles_being
discussed are still the same. Just depends on where the power co. (and the
AHJ) wants the connection......besides, the main panel (or disconnect) isn't
usually very far from the meter.
