No the re-bar will rust in the ground when exposed to the ground dampness. This will cause the rod ground resistance to gradually increase. Approved ground rods are either copper clad or galvanized. In locations where it is impossible to drive a 10 foot rod into the ground the electrical code has approved ground plates that can be dug in and buried at two feet in depth. You want the resistance to be as low as possible on a grounding circuit. Alternatively, if that re-bar is part of the concrete foundation (Ufer ground) of the structure (and at least 20 feet long, 1/2" min. diameter) it is a perfectly acceptable grounding electrode.

When installing the ground rod what is the maximum distance from the ground rod to the secondary distribution center?
5 feet
What is an earth rod?
A long metal rod hammered into the ground to act as a grounding post.
Why are you getting 120 volts from hot wire and grounded rod?
On a North American electrical distribution system this is quite normal and natural. The neutral connection point in a distribution panel is connected to the ground rod via the ground wire. So in effect the ground rod and the neutral are one in the same.
What size ground wire for a 200 amp service panel to the water meter?
#6 should be fine...Canadian Code anyway....
What metal is a lightning rod made of?
Any metal that will conduct electricity. Steel works fine, since it is strong. A ground rod driven into the ground and connected to the lightning rod with a wire or cable. The ground rod is usually copper clad (or plated) steel.
How do lighting rod work?
The lightning strikes the rod and the rod safely directs the lightning to the ground to keep the house safe.Otherwise,the lightning would discharge onto the roof and likely cause a fire.
When installing the ground rod what is the maximum distance from the ground rod to the secondary distribution center?
5 feet
In a typical electrical panel installation the main ground wire is connected directly from a ground rod driven into the ground to the?
The ground wire should come from the ground rod and to the main electrical panel grounding terminal.
How do you ground a CB radio antenna?
Grounding is accomplished by connecting a heavy cable from the ground side of the antenna to a ground rod. A ground rod is typically a 4 - 8 foot copper plated steel rod driven into the ground as close as possible to the antenna, making the wire connection as short as possible. All equipment should also be grounded to a rod, not just the antenna.
What is an earth rod?
A long metal rod hammered into the ground to act as a grounding post.
How do you use bentonite in electrical grounding?
Bentonite has an affinity for water. By packing Bentonite around the ground rod it increases the conductivity of the ground rod. Ground rods are not supposed to have a resistance above 5 ohms when compared to the utility's ground grid. Getting the ground rod into this resistance zone in bad soil conditions is aided by the use of Bentonite.
What a lightning rod?
A lightning rod is a metal rod placed in various structures to prevent lightning from striking them. It attracts the lightning to itself, and it is channeled into the ground.
How many grounding clamps are permitted on one ground rod?
As long as the clamp is of an approved type only one is needed per ground rod.
Would a lightning rod mounted on the first floor of a tall building work?
No. Since lightning often strikes tall objects first the lightning rod on the first floor would not allow the current to be safely sent to the ground.
Why are you getting 120 volts from hot wire and grounded rod?
On a North American electrical distribution system this is quite normal and natural. The neutral connection point in a distribution panel is connected to the ground rod via the ground wire. So in effect the ground rod and the neutral are one in the same.
How tall is a lightning rod?
it doesn't have a fixed length, as long as a rod is "grounded" connected to the ground by a heavy duty wire, it's a lightning rod. . .
How does EARTH rod controls the leakages of electricity?
It acts as a ground
