Good day, Has anyone else noticed the requirement to disconnect the grounded conductor from a fuel dispenser has disappeared? The 2017 NEC apparently lost this requirement that has been around for many years. Any insight as to why? I understand this was an effort to match NFPA 30A 6.7 but is it no longer necessary to disconnect the grounded conductor?
Hey Grant thanks for your question. You are correct 514.11 was revised in the 2017 NEC based on First Revision No. 3996. There were two Public Inputs that addressed the location of emergency shutoff devices or electrical disconnects for both attended and unattended self-service motor fuel dispensing facilities. The panel statement in the First Draft Report for FR3996 is " Section 514.11 is revised to reflect the requirements in NFPA 30A- 2015." No other explanation for the removal of the specific rule for disconnecting grounded conductors. If anyone, such as from CMP14, knows of the specific reason please send in a comment and we will publish it.
