Can anyone who has access to this document tell me whether its definition of "manhole" is such that a vault that sits under a transformer would meet that definition?
That requires a university log in. Also, IEEE Xplore requires a subscription. But thanks anyway.From the University of Michigan library system.
I have always treated the vaults you described as "manholes" in my refinery experience.manhole (1) (More accurately termed splicing chamber cable
vault) A subsurface chamber, large enough for a man to enter,
in the route of one or more conduit runs, and affording facilities
for placing and maintaining in the runs, conductors,
cables, and any associated apparatus. See also: splicing
chamber. (PE/T&D) [10]
(2) An opening in an underground system that workmen or
others may enter for the purpose of installing cables, transformers,
junction boxes, and other devices, and for making
connections and tests. See also: distribution center: splicing
chamber. (BT) [34]
(3) A subsurface enclosure that personnel may enter used for
the purpose of installing, operating, and maintaining submersible
equipment and cable.
