Bonding Gas Piping
Section 250.104(B) requires gas piping to be bonded, "if it is likely to become energized." How to bond the gas pipe, where to bond it, when to bond it, and the size of the bonding jumper are all important questions.

"I have an amazing talent: I know almost every song that has ever existed."
The rich man laughs.
The poor man says,"I am willing to bet you all the money you have in your wallet that I can sing a genuine song with a lady's name of your choice in it."
The rich man laughs again and says, "Ok how about my daughters name, Joanna Armstrong-Miller."
