I was recently asked about the bonding and grounding requirements of CSST pipe. I hear some say the companies say there stuff is safe and then some say the NEC has a section on it and if I remember right it is 250.104 or 106, cant remember the exact section now.

It then refers you to table 250.122 and thats what i dont understand. The piple does not have an amp. load.

Any help?
 
The NEC does not have a section for CSST.

What has happened is that there was a lawsuit and now the makers of CSST require bonding of the CSST beyond any NEC requirements.

Try Googling CSST bonding

We meaning you personally or we meaning electricians?
 
As a Building Official, I make sure that as a precondition of the issuance of a Certificate of Occupancy I have the plumber/gas installer bond their black iron manifold(s) (where the csst connects) with a #6 to the electrical system grounding electrode system. This was spelled out in the amended manufacturers installation instructions. Not covered by 110-3(b), so electricians aren't technically responsible....just the gas-people. :smile:

So does the gas man know what he's doing when he's bonding a grounding electrode system?
 
In the great Commonwealth of Massachusetts the gas guy would be violating the law if he bonded it.

I agree, but that does not mean it's my problem either as it is not NEC required.

If they want to install this stuff they will need to pay an EC to bond it.
 
The North Carolina Electrical board has sent out a letter saying that you must at least be a Limited Electrical Contractor in order to bond the pipe.

The Special-Plumb. and Heating license is not sufficient. So in NC it is back on the electrician.

That's what I'm there for.To make sure he's doing his / her job. :smile: I'm assuming that's what inspectors do.

Here is an interesting story about a CSST installation.


There is a multiunit building with residences.


One of the tenants was complaining that his floor was excessively hot to walk on. He complained every week for 3 months. So the management company finally decided to go to a downstairs unit to open the ceiling and see what they could see.
To their horrow and dismay, they found a CSST pipe running through the ceiling...with a blue pilot like flame comming out of it. That was the source of heat for his floor. They contacted all of the residents and asked if anyone else felt warm floors. There were a total of 3 different locations where the CSST was leaking and lit - possibly the turning on and off of the high hats ignited the "pilot lite" like flames.

Today they are testing each and every unit for leaks.

Do you think the plumber is freaking out???:D

Code Ref? that states you only use the NEC? In Florida you use the NEC and any other code that applies as adobted by Florida Statute. NEC. Florida Building Code and others. All equipment installed must follow manufactures instructions. I have found some 50 amp GE ranges as per manufacturers instructions. That does tork some jaws when you find it on the final of a 2 story house.

You gonna charge the plumber for bonding if he uses copper pipe instead of plastic?

:D

Fair enough. :)

I am not saying it does not have to be done.

I am saying if the plumber chooses to install this pipe they will have to pay the EC to bond it.

No different then if the plumber chose to install a pump to make his life easier....he would have to pay an EC to wire it.
