What's the CPWD DSR rate for circuit / submain wiring?
The wiring runs that feed your light and power circuits from the DB — phase + neutral + earth in conduit, priced per metre by conductor size. 2.5 sq.mm is the standard light circuit; 4 and 6 sq.mm feed power circuits and submains.

Notes
- These per-metre items are how you price the DB-to-circuit backbone; the point wiring items (light point, plug point) then take over from the switch board.
- Rates shown are CPWD Delhi base rates from DSR E&M 2022 (CPWD), edition 2026-06-12 — apply your local market / cost-index variation.
