Utility Manholes and Handholes
Cross-references point to the standards that now own the topic after the October electrical rewrites: MV cable to medium-voltage-cables, energy storage to battery-energy-storage-systems, service grounding to grounding-and-bonding, lightning to lightning-protection.

description: >
When to use: Selecting and specifying below-grade access structures for underground electrical and low-voltage systems — precast concrete manholes (personnel-entry), precast concrete handholes/vaults, and polymer-concrete or composite handholes serving medium-voltage feeders, low-voltage distribution, lighting circuits, and communications/data ductbanks. Covers ductbank pull points, cable splice and termination locations, inspection access, cover and frame assemblies, load/tier ratings, cover markings, sumps and drainage, grounding/bonding attachments, pulling irons, and cable rack inserts.
− Not intended for: Underground conduit/ductbank routing, trench design, and concrete encasement (see [[sync/underground-ductbank]]); conduit and raceway material, fittings, and methods (see [[sync/raceways-and-conduit]]); conductors, cables, splices, and cable tray (see [[sync/conductors-and-cables]]); broader storm/sanitary/water/gas main coordination (see [[sync/site-utilities]]); above-grade pull, junction, and outlet boxes; AASHTO bridge-loaded roadway manholes; and wet-well or sump-pump drainage structures.
+ Not intended for: Underground conduit/ductbank routing, trench design, and concrete encasement (see [[sync/underground-ductbank]]); conduit and raceway material, fittings, and methods (see [[sync/raceways-and-conduit]]); shielded conductors above 1000 V and their joints (see [[sync/medium-voltage-cables]]), low-voltage conductors and cables (see [[sync/conductors-and-cables]]), and cable tray (see [[sync/cable-tray]]); broader storm/sanitary/water/gas main coordination (see [[sync/site-utilities]]); above-grade pull, junction, and outlet boxes; AASHTO bridge-loaded roadway manholes; and wet-well or sump-pump drainage structures.
