3.3.59.2 Sources ofIgnition. Appliances or equipment that,
because of their intended modes of use or operation, are
capable of providing sufficient thermal energy to ignite
flammable gas-air mixtures.
I suppose if receptacles are used as disconnects in "their intended modes of use or operation" this might apply but it is clear the NFPA 54 people don't talk to the NFPA 70 people very often.
I am still not sure why a gas meter, piped in with threaded black iron pipe is more likely to leak than a space heater hooked to a bent up piece of CSST but I guess that is why I am not the plumbing inspector.
