How to write a electrical panel upgrade permit narrative
A service upgrade touches the utility, the meter, and every branch circuit in the house, so reviewers read these applications closely. Your narrative needs to name the amperage change, the equipment, the conductor sizes, and the grounding work — in plain language a plan reviewer can approve without calling you.
What your narrative needs to include
- Existing and new service amperage (e.g. 100A to 200A)
- Panel make, model, and rating
- Service entrance conductor size and material
- Grounding electrode system work (reviewers look for NEC 250 compliance)
- Whether the meter base is being replaced, and the utility coordination note
- What is excluded — the utility side, subpanels, branch circuit rewiring

Project Description
This project involves upgrading the existing electrical service at the subject property from 100-ampere to 200-ampere capacity to meet current residential load requirements. The work includes replacement of the main service entrance equipment and associated wiring from the utility meter to the new panel location.
Scope of Work
- Remove and dispose of existing 100A main breaker panel
- Install new Square D QO 200-ampere main breaker panel at existing panel location
- Replace service entrance cable from meter base to new panel with 2/0 AWG copper conductors rated for 200A service
- Install new 200A main disconnect breaker
- Transfer all existing branch circuits to new panel with new breakers
- Install new grounding electrode system per NEC 250
Materials & Methods
Square D QO 200A indoor main breaker load center (QO140L200PG or equivalent). Service entrance cable: 2/0 AWG copper. All work performed per the currently adopted NEC with local amendments.
Work Not Included
Utility company service upgrade (separate utility coordination required). Subpanel installations. Branch circuit rewiring beyond the panel.
Contractor Statement
All electrical work will be performed in accordance with the National Electrical Code as locally amended. Final inspection will be requested upon project completion.
Mistakes that get electrical panel upgrade permits kicked back
- Writing "upgrade panel" with no amperage — the single most common kickback
- No mention of grounding; reviewers check for it on every service change
- Forgetting to state the utility side is excluded, which triggers scope questions
- No conductor size, so the reviewer cannot verify the service rating
