Hi Guys,
I've got an oil filled distribution transformer located indoors that utilizes electrical grade mineral oil. The transformer will be placed on a concrete pad. I'm looking at NEC 450.23, it requires an automatic fire extinguishing system and a liquid confinement area. Is mineral oil considered a "less-flammable liquid that has a fire point of not less than 300C"?.
It seems an overkill to provide a vault for a 25kvA xfmr installed in an enclosure.
Any ideas?
Thanks,
EE
