Eletrical Grounding
Eletrical Grounding
(OP)
I work in NYC I am a plumber and have allways seen the electrical service grounded to the water main. Now keep in mind I work in new construction high rise buildings I have gone to this new job and the electrical contractor will not give a reason why he has not bonded his service to the water main except citing re cent code changes now I have been in a few buildings since the changes here and all have there services bonded to the water main! I even fought with one contractor in 2 buildings about him trying to bond to the gas service can any one give me info because I feel this is a dangerous thing happening

A connection to gas piping is not required by any code to my knowledge.

Things such as:
-Packaged Gas-Electric Air Conditioning units
-Gas Clothes Dryers
-Gas Barbeque with electric strike start
-Gas fired water heater connected to Jacuzzi/pool/Sitz bath pump systems
-Natural gas fired sterilizers in hospitals
-Commercial laundry tunnel washer/dryer systems
-Gas fired power generation equipment
There are numerous pieces of equipment where gas connectons and electrical connections enter adjacent to each other. This is very common in many healthcare, industrial and commercial facilities.
We always bond natural gas piping systems. They are not used as a grounding electrode, they are just bonded to assure that should an accidental fault occur, there is a path to dissipate the energy.
RE: Eletrical Grounding
I wouldn't have thought to consider that as likely to become energized because it seems to me in most cases the piping is effectively connected to the frame of the appliance via it's fittings. Is a bonding jumper always required? I don't do healthcare facilities, but could understand those having more stringent requirements.
