Actually, an earth connection is very over rated by ham radio operators and with few exceptions based upon antenna design, radios don't need an earth connection to work.For the average homeowner that is not into ham radio what benfit is provided by a good connection to dirt?
The point is that what does "effective" mean as far as earthing goes for the vast majority of cases. In most cases a 1000 Ohm connection is quite adequate. There is this myth that somehow all bad things electrical can be shunted off into the Earth by a "good" earth connection. That is just plain false.Personally, I don't think a near 1000 ohm connection is fine. It's a code minimum. We put in rods because we are allowed to and the customer doesn't care about a good connection to ground. At least a CEE works.
None of the above relates to whether or not an earth connection is good, bad or otherwise. It's just that two rods have been shown to be nearly ineffective in our area, but we have to use them anyway. If we are bound by code to use an earthing electrode, at least it should be one that has been shown to be effective.
<rant>I've yet to meet a homeowner customer that even cares about ground rods or what they do.
If they see me installing a second rod they usually have to ask why one isn't enough.I've yet to meet a homeowner customer that even cares about ground rods or what they do.
I just ask them if they want to move in. Cause if I don't you won't move in until I do what the CODE requires.<rant>
If I could get back the time I've spent explaining to customers why we have to have the ground rods, and where the heck is an acceptable location to install them in their homes, and why they will not get electrocuted by the bare copper wire, blah blah blah, etc., I could maybe be retired by now.
I'm dealing with customers who already live in their homes. But same thing, the won't get their net metering credits if they don't pass inspection.I just ask them if they want to move in. Cause if I don't you won't move in until I do what the CODE requires.
And if you don't believe me ask the inspector.
