Scottpat Posted June 18, 2014 Report Share Posted June 18, 2014 Les, check with Bruce Barker. For some reason I think I recall him having some. I have plenty with no bonding! Quote Link to comment Share on other sites More sharing options...
Les Posted June 19, 2014 Author Report Share Posted June 19, 2014 Thanks Scott. Bruce will be happy to hear from me! Quote Link to comment Share on other sites More sharing options...
Jim Port Posted June 19, 2014 Report Share Posted June 19, 2014 The CSST is bonded by the connection to the steel. There is not an additional bond to the CSST. Quote Link to comment Share on other sites More sharing options...

Jim Katen Posted June 19, 2014 Report Share Posted June 19, 2014 The CSST is bonded by the connection to the steel. There is not an additional bond to the CSST. The NEC doesn't require it but the CSST manufacturer's do. (Except with the new fancy CSST.) Quote Link to comment Share on other sites More sharing options...
inspector57 Posted June 19, 2014 Report Share Posted June 19, 2014 The CSST is bonded by the connection to the steel. There is not an additional bond to the CSST. The NEC doesn't require it but the CSST manufacturer's do. (Except with the new fancy CSST.) I think what was meant is that CSST tubing is NOT bonded DIRECTLY but is bonded by bonding a section of regular pipe to which the CSST is attached. The point being that the manufacturers specifically forbid trying to bond CSST itself. Any bonding is done at the iron pipe or fittings designed for the purpose (never have seen those yet).

Jim Port Posted June 20, 2014 Report Share Posted June 20, 2014 Correct JL, I was thought I was clear when I said the bond for the CSST occurred by the connection on the black steel, not the CSST. Quote Link to comment Share on other sites More sharing options...
Les Posted June 20, 2014 Author Report Share Posted June 20, 2014 am I to understand there is never an instance where the csst would have a fitting/device that connects directly on the csst for the bond? always to steel and carry to csst? Nice photo, that is what I wanted - thanks! Quote Link to comment Share on other sites More sharing options...
Ben H Posted June 20, 2014 Report Share Posted June 20, 2014 It's my understanding you can take the bonding point to the nut of the CSST, just not the tubing itself. I did mine right as the black iron pipe enters the house. I then checked the resistance with my meter between the nut of the CSST and the bond point and it was less than a couple ohms. Seems to me there is no difference in my house. Quote Link to comment Share on other sites More sharing options...
