Grounding means connection of a copper wire, often bare copper – to your gas line, then connecting the other end to your homes grounding system. National Electrical Code requires all homes to have a grounding system. This system consists of a ground rod (8′) driven in the ground close to your electric meter.
Can you ground a gas line to a ground rod?
ANSWER: Yes, I said metal gas piping should be bonded to the supply system grounded conductor. Section 250-104(b) does require that metal gas piping should be bonded to the grounding electrode system. This can be done by terminating at the neutral bar, or any of the electrodes in the grounding electrode system.
Should a gas line be grounded?
CSST Gas Lines Must Be Grounded Since 2009, US building codes have required CSST to be bonded and grounded for safety, but that was not required during the first 18 years. The reason for this safety precaution is that a nearby lightning strike could cause the systems in your structure to become electrically energized.
Do you have to ground black gas pipe?
3 Answers. According to National Electrical Code, the pipe has to be bonded. However, it can be bonded using the grounding conductor serving the equipment that uses the gas.
Where does a gas line need to be grounded?
3.14(a) in NFPA 54 requires each aboveground portion of a gas piping system upstream from the equipment shutoff valve to be electrically continuous and bonded to any grounding electrode. Sec. 250-104(b) of the National Electrical Code (NEC) agrees with this mandate.
How far should a ground rod be from a gas line?
The NEC requires all driven rods to be a minimum eight feet in the earth and for multiple connected rods a minimum spacing of six feet between rods.
Does flexible gas line need to be grounded?
CSST flexible gas piping must be bonded to reduce the risk of damage due to a lightning strike on the home. The most common issue that home inspectors find is the CSST system is not being properly bonded. You can see that the bonding clamp is over the yellow sheathing which will not enable a proper bond.
What is difference between grounding and bonding?
Bonding is the connection of non-current-carrying conductive elements like enclosures and structures. Grounding is the attachment of bonded systems to the earth. Both are necessary to safeguard people and property from electric hazards.
Why do you need to bond a gas line?
When it comes to gas piping, not so much. Specifically, electrical potential. If the metal accidentally carries electricity or even a static charge, proper bonding will allow the electricity to be carried back to its source in a safe manner. Oftentimes, there will be so much current that it trips a circuit breaker.
Can you earth to a gas pipe?
The main earth bonding for the gas pipe should be done after the gas meter in 10mm bonding and not more the 60cm or after 1st tee off. The cross bonding under the boiler should connect all pipework and be done in 4mm bonding.
How do you ground a gas furnace?
A common trick is to put a jumper on the ground on a grounded outlet. A common trick is to hook the neutral and ground together in the furnace and then physically connect the ground wire to the gas line.
What size wire do you need to bond a gas line?
The bonding conductor must not be smaller than a 6 AWG copper wire or the equivalent size if made of aluminum. The means for attaching the bonding conductor to the grounding electrode system must be in accordance with NFPA 70. The bonding conductor must be not longer than 75 feet (22,860 MM).
Where do you bond the gas pipe?
Corrugated stainless steel tubing (CSST) gas piping systems shall be bonded to the electrical service grounding electrode system at the point where the gas service enters the building. The bonding jumper shall be not smaller than 6 AWG copper wire or equivalent.
How much does it cost to ground a CSST line?
How Much Does It Cost? As with most electrical repairs the cost can vary significantly based on many factors, but a good rule of thumb would be between $150 – $500 for most single-family homes in Central Iowa.
Can Home flex gas line be buried?
Can it be buried? Yes, however it must be sleeved in a non-metallic conduit ½” larger than the pipe. HOME-FLEX CSST has been tested and certified by CSA and IAPMO for compliance with the industry standard ANSI LC-1 / CSA 6.26, “Fuel Gas Piping Systems using Corrugated Stainless Steel Tubing (CSST).”.
What is the black flexible gas line?
The black conductive jacket of CounterStrike® has been shown to be up to 400 times more resistant to the damaging effects of electrical energy than yellow CSST. It also lays straighter and pulls easier than yellow CSST.
Is Home flex gas line safe?
In short, flexible gas lines are perfectly safe as long as they’re properly installed. A CSST that is not correctly grounded or bonded can leak natural gas or become ignited, leading to a major fire hazard.
Why does a grounding rod have to be 8 feet?
The NEC and UL require a ground rod to be at least 8 feet in length. This specification was obviously created by engineers that had never driven a ground rod or noticed that most people are not 8′ tall. Longer rods are more dangerous to install and bow more when being driven.
How much is a ground rod?
8′ ground rods cost about $11 apiece – 10′ if required in your area about $15 each. The grounding wire, assuming #4 bare copper wire, about $1.20/LF, 4 clamps at $5 ea – so assuming about 10′ run to each rod, then about $66-74 materials – say maybe $80-90 with markup.
What can be used as a grounding rod?
There are 8 items that are listed in 250.52 as allowable grounding electrodes, here is the list: Metal Underground Water Pipe. Concrete-encased Electrode. Metal In-ground Support Structure. Ground Ring. Rod and Pipe Electrodes. Plate Electrodes. Other Listed Electrodes. Other local underground metal systems or structures.
