I have been asked to classify a location for outdoor receptacles to supply power for block heaters for tank trucks containing propane gas.
The trucks are in an area where small propane tanks are stored outside. There is also a filling station about 200ft. away.
I looked at NEC section 500.4(A) That requires documentation. My question is who must supply this documentation?
