What's the CPWD DSR rate for a TPN (three-phase) distribution board?
For a three-phase connection, the vertical TPN MCB distribution board with copper bus bar, neutral link and earth bar — supplied and fixed, but WITHOUT the MCBs and incomer, which are added per piece. 8-way suits most three-phase homes.
Preliminary Using CPWD DSR E&M 2022 item rates as published, this worked scenario adds up to ₹10,165 (items 2.5.2). The item rates are CPWD's Delhi base rates; the quantities and the item mix are NirmanDost's scenario, not a CPWD bundle — adjust both to your site and apply your local cost index.

Notes
- Budget the MCBs, RCCBs and the incomer separately — the board item is the empty, bussed enclosure. See the related recipes for those rates.
- For a single-phase home, the SPN board recipe is the right one.
- Rates shown are CPWD Delhi base rates from CPWD DSR E&M 2022, as published (our extract of the book is dated 2026-06-12) — apply your local market / cost-index variation.
- CPWD has published later editions since (its site lists DSR E&M 2025); the 2022 figures here are reference rates, not the schedule in force for a current tender.
- The item mix and quantities on this page are a NirmanDost worked scenario; the rates, units and descriptions in each row are CPWD's, verbatim. Every code opens in CivicMate for the source row.
