Thanks again for your input. Do you know if there are different electrical codes for grounding water pipes in the presence of natural gas (i.e. class room environment)?
Blu: Rather than take up all the band width to type out the code requirements concerning electrical grounding and gas piping, might I suggest that you read section 309 (IFGC)Electrical.. 309.1-Electrical bonding and grounding. 309.2-Grounding.(Floida Building Code) 309.3-Connections.(Florida Building Code) MOE
