How to write a new circuit / wiring permit narrative
New circuit permits are usually fast approvals — if the reviewer can see the load, the wire size, and the overcurrent protection at a glance. Vague applications ("adding some outlets") are what slow them down.
What your narrative needs to include
- What the circuit serves (EV charger, hot tub, kitchen appliance, garage outlets)
- Circuit rating and breaker size (e.g. 50A two-pole GFCI breaker)
- Conductor type and gauge (e.g. 6 AWG copper THHN in EMT)
- Where it originates (panel location, available capacity)
- GFCI/AFCI protection where required

Project Description
This project involves installation of one new dedicated 240-volt, 50-ampere branch circuit to serve a Level 2 electric vehicle charger in the attached garage. The circuit originates at the existing 200A main panel, which has verified spare capacity.
Scope of Work
- Install one 50A two-pole breaker in existing main panel
- Run 6 AWG copper THHN conductors in 3/4-inch EMT from panel to garage wall location, approximately 35 feet
- Install NEMA 14-50 receptacle in surface-mount box at 48 inches above finished floor
- Label circuit at panel directory
Materials & Methods
6 AWG copper THHN conductors, 3/4" EMT conduit with compression fittings, NEMA 14-50 receptacle, 50A two-pole breaker matched to panel manufacturer.
Work Not Included
EV charger equipment installation beyond the receptacle. Panel replacement or service upgrade.
Contractor Statement
All work will be performed per the currently adopted National Electrical Code, including load calculation verification of available panel capacity.
Mistakes that get new circuit / wiring permits kicked back
- Not naming the load the circuit serves
- Missing breaker size or wire gauge
- No statement that the existing panel has capacity, prompting a load-calc request
