Systems less than 50 volts have to be grounded, where supplied by a transformer, if the transformer is supplied (on the primary side) by an ungrounded electrical system.
How to connect a 6 wire meter?
Place one end of the No. 6 wire through the proper hole in the bottom of the meter base. Leave enough slack to connect it to the small ground lug. Strip a half inch of insulation off the No. 6 wire. Place the No. 6 wire under the ground lug, and tighten it securely.
How to make a hole in a meter base?
Scoop out about three inches of dirt under the meter base to make a shallow hole. Drive the ground rod into the hole in the ground directly under the meter base using the sledgehammer until the rod only has a few inches left above the bottom of the hole. Place the ground rod clamp on the ground rod, and tighten it securely using the adjustable wrench.
How to secure a 6 wire to a panel box?

What is required is that one end land on the grounding electrode (the first five feet) and the other end could land at any accessible point on the metal water pipe up to and including the far end to the hot water pipe.
How far does a metal pipe extend from the house?
For example; a metal pipe extends only nine feet from the house and non-metallic pipe is installed from that point to the water supply no grounding electrode conductor is required. How to bond the interior metal water pipes has been the subject of many debates.
What is the bonding requirement for a metal water pipe?
If the metal water pipes are not 100% metal water pipes then the bonding requirement moves to 250.104 (B) and the equipment grounding conductor for the circuit likely to energize the pipes can be the bonding conductor.

According to the National Electrical Code, or NEC, a ground system should have a grounding resistance of 25 ohms or less. 2 Achieving this may require more than one ground rod. 01 of 05.
Why is grounding important?
In your home's wiring system, the grounding system is a critical safety feature. In the event of some kind of breakdown in the system , the grounding system provides a path of least resistance that ensures current will flow safety back to the earth itself. It thu s reduces the chances that a short circuit can cause a fire or life-threatening shock.
What is ground rod?
Ground rods, also known as grounding electrodes, are used to connect the grounding system of electrical systems to earth ground. Ground rods can be made with many different materials, but copper is the most common material used for residential installations.
