You are designing distribution for a seven unit townhouse with in slab conduits. What is the MINIMUM number of 27 mm (1 in) rigid PVC Type 2 or metallic conduit that is required to satisfy…

Three conduits is insufficient because the standard mandates individual conduit pathways for each unit, not shared distribution across multiple units.

Four conduits does not satisfy the one-per-unit minimum requirement for a seven-unit building.

Five conduits leaves two units without a dedicated in-slab conduit pathway, violating the minimum per-unit distribution requirement.

Residential telecommunications cabling standards require a minimum of one dedicated 27 mm (1 in) rigid PVC Type 2 or metallic conduit per dwelling unit when in-slab distribution is used. Since there are seven units, a minimum of seven conduits must be provided - one serving each unit individually to ensure independent distribution pathways and future serviceability for each residence.

Fourteen conduits may be used for enhanced or redundant distribution but exceeds the minimum requirement; the standard only mandates one conduit per unit as a baseline.
