Outlets near propane tanks.

[Doctor Electric]

Hey guys im so happy you are all here i rarely use this but it is very useful and I'm very appreciative!! Customer wants to run under ground to two separate location outlets by two separate location propane tanks (one per). Its residential. In ohio Where can i find requirements if any on the installation in the code book or would this be a city thing???

Start with Article 500. Pick a year. Keep reading until you’ve hit 518. I included 517 because while you’re in the hospital, after ignoring the previous articles, you will have a better understanding of that system.

Yes, it pertains to your residential area and it is not just a city thing. Ask any lawyer.

Hmm, propane is heavier than air, so if it leaks it will collect in low lying areas, like basements, yet there is no prohibition on regular wiring methods in basements with propane appliances. Outdoors the propane will just flow along the ground from a leak source.

Yes, everytime the propane tank gets filled some escapes. Is that enough to cause the HAJ to consider it a 500 series issue? Have to ask them.

I agree, most likely it is not an issue, but read up on it anyway.

NFPA 58 Liquefied Petroleum Gas Code

6.22.2.2 Fixed electrical equipment and wiring installed within a classified area specified in Table 6.22.2.2 shall be installed in accordance with NFPA 70, National Electrical Code.
6.22.2.4 The provisions of 6.22.2.2 shall not apply to fixed electrical equipment at residential or commercial installations of LP-Gas systems or to systems covered by Section 6.23.

But still good practice
NFPA 58
-Tank to source of ignition if filled on premises-10 feet
-Regulator vent termination to source of ignition-5 feet

NFPA 54, National Fuel Gas Code.
5.7.2.3

Gas meters shall be located at least 3 ft (0.9 m) from sources of ignition.

API500


NFPA 497


NEC 2017
500.5

(B) Class I Locations. Class I locations are those in which flammable gases, flammable liquid–produced vapors, or combustible liquid–produced vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. Class I locations shall include those specified in 500.5(B)(1) and (B)(2).

Informational Note No. 1: This classification usually includes locations where volatile flammable liquids or flammable gases or vapors are used but that, in the judgment of the authority having jurisdiction, would become hazardous only in case of an accident or of some unusual operating condition. The quantity of flammable material that might escape in case of accident, the adequacy of ventilating equipment, the total area involved, and the record of the industry or business with respect to explosions or fires are all factors that merit consideration in determining the classification and extent of each location.

minimum distance from meter socket

Just recently purchased home here in CT. Need to replace electric meter. The house has a propane tank and the regulator is about 2 feet away from the meter. Is this okay. What is the code for distance the tank has to be from the meter socket?
