Grounding to water pipe

Keep in min you still MUST bond to the steel rebar in the foundation, the gas main, the water main, the cable entrance, the telco ground , any lightning protection system, your swimming pool ground , and any other ground system, just as before. It is just that you may not count these as grounding electrodes anymore. I was assuming your water meter was in the house no need to add a jumper at you water meter. For providing ground to your main service panel, the panel is usually connected to the water supply line if that pipe is metal. This is typically done inside the house, particularly on older houses.

If your water supply line is plastic, you will have grounding via other means such as ground spikes driven down either outside or through your. In the video I talk about why water pipes need to be grounded. The GEC would be ground rods back to the panel and a suplement GEC may be required. All of the following electrodes that are present at a building shall be bonded together to form the entire grounding syste1.

If you have a Electric water heater it needs to be grounded. Pipes can no longer be used as a ground inside of a house. Your Well Pump does need to be grounde and you can do that.

Therefore, installers frequently look to water piping systems for this purpose, particularly if they are in the same area. The first question is when is a water pipe a water pipe. Metal pipes are required by code to be electrically grounde and this is normally done by grounding the cold water inlet pipe to the home.

The water heater creates a break between the cold water pipes and the hot water pipes in the home. Several years ago, this setup was allowe but with the increased popularity of nonmetallic water pipe and fittings, there’s too much chance of an interruption in the metallic piping to allow its use for something as important as a grounding conductor. The grounding electrode system normally requires two ground rods, one water pipe exiting the house underground (if metal), and one concrete embedded re-bar (if any).

Additional ground rods used for other purposes such as antennas must also be bonded as part of the grounding electrode system. Metal water piping system(s) installed in or attached to a building or structure shall be bonded to the service equipment enclosure, the grounded conductor at the service, the grounding electrode conductor where of sufficient size, or to the one or more grounding electrodes used. Grounding and Bonding of Gas Piping.

A supplemental grounding electrode is always required if water pipe is used. A metal underground water pipe in direct contact with the earth for 3. Your cold water pipe is not an effective ground. A ground is a direct electrical link back to the transformer from where the power was created(on the power pole behind your house). Enjoy easy ordering, quick delivery, and great prices, plus free shipping on select purchases! The water pipe is only a grounding electrode, just like a ground ro and also serves as the water piping bond.

Used to connect grounding conductor in rigid conduit to water pipe for grounding. Copper strap allows flexibility during grounding and helps protect conduit system from the effects of vibrations in water system. Available with 360° swing hub (GLH). Cast from high strength, highly conductive copper alloy.

A GOOD grounding system is needed and the water pipe can cause a myriad of other problems. Water Pipes for grounding. Handrail Air Terminal Support. Notched Cast U-Bolt Pipe Clamp.

This piece of copper pipe is required to be bonded to the ground under the National Electrical Code Article 250. A) and under the AWWA standards. This mandatory ground wire to your copper pipe will provide a source for the stray currents in the water to leave your system and go to ground.

This grounding wire should be continuous, through both pipe clamps securing it to the water piping before and after the water meter, and continuing into the main electrical panel where it joins the ground bus and neutral bus. These pipe clamps are ideal for connecting copper conductors to metallic water pipe (including copper tubing) or ground rods. Bronze clamp has many uses such as bonding to ground rods or copper water pipes. Technical Notes Meets NFPA requirements for bonding to stainless steel gas piping. I think some are confusing using the water pipe for a ground and bonding the water pipe to the electrical system ground.

You still are required to bond copper plumbing to the electrical system ground. A common grounding issue in older homes concerns ground “taps” or connections from the ground prong opening on a wall outlet to the nearest cold water pipe (such as under the kitchen sink). Connect copper ground wire to water pipe , copper tubing or ground rods. Simple ham station grounding is often done with a water pipe.

Indeed a metallic cold water pipe can serve as a basic ground for ham gear. Since outside water pipes normally are buried well below the soil’s surface, it does serve some purpose. Even thought he water could conduct small amounts of electricity, the bonding of metal piping systems is to reduce the touch potential danger.

Since plastic is an insulator, there is no touch potential. The amount of electricity that could be carried by the water in a plastic pipe would not normally be dangerous.
