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.

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 DSR E&M 2022 (CPWD), edition 2026-06-12 — apply your local market / cost-index variation.
