Dedicated Circuit Installation & GFCI Protection

New 20A dedicated circuit from panel to kitchen or garage outlet with proper wire routing and code compliance.

1. Circuit planning & permitPull the required permit for new circuit work before beginning. Confirm the panel has a free 20A slot (or tandem breaker availability per the panel's labeling). If the panel is full, present options to the customer: install a tandem breaker if space allows, add a subpanel, or evaluate other options. Plan the wire route from the panel to the outlet location — avoid running wire through exterior walls where possible to minimize insulation disturbance. Determine if walls need to be opened or if the wire can be fished through wall cavities. Photograph the existing panel before opening it.
2. Outlet box location & rough-inMark the outlet location per customer preference and code requirements — kitchen counter outlets must be within 24" of any point along the counter per NEC 210.52. Install a single-gang or duplex outlet box rated for the application — use an old-work cut-in box for finished walls (ensure it mounts securely to the drywall without movement). Verify outlet height is consistent with existing outlets in the room (typically 12" from finished floor to center of box). Do not locate outlet boxes in any location where drilling to the panel would require penetrating fireblocking that cannot be properly repaired and re-protected.
3. Wire routing & fishingDrill 3/4" holes through top plate and bottom plate aligned to the outlet box location. Use a flex bit or right-angle drill to drill through plates without opening the wall further. Fish 12/2 NM cable from the panel location to the outlet box using a fish tape or fish sticks. Where cable must pass through fireblocking, use an approved firestop caulk or putty to seal all penetrations after wire is in place — this is a code requirement in all jurisdictions. Secure the cable to framing every 4.5 feet and within 12" of each box with appropriate staples — do not staple through insulation.
4. Panel connectionTurn off the main breaker before opening the panel. Verify the main is off with a non-contact voltage tester on the hot bus before touching any panel components. Remove a knockout for the new circuit's cable entry and install an appropriate cable connector. Strip the cable jacket 6" inside the panel. Connect the black (hot) conductor to the new 20A breaker's terminal — leave sufficient wire to reach the breaker without tension. Connect the white (neutral) to the neutral bus bar and the bare copper ground to the ground bus bar. Torque all connections to the manufacturer's specifications (typically 20 in-lbs for 12 AWG lugs).
5. GFCI outlet installation & wiringStrip 3/4" of insulation from the cable conductors at the outlet box. Connect the black wire to the GFCI outlet's LINE hot terminal (brass screw or terminal labeled LINE). Connect the white wire to the LINE neutral terminal (silver screw). Connect the bare copper ground to the green grounding screw. Do not use the LOAD terminals unless intentionally protecting downstream outlets on the same circuit. Fold wires carefully into the box — do not force the outlet in with crushed or kinked wires. Install the outlet in the box with the ground slot down (standard orientation). Install the cover plate and verify it is flush with the wall surface.
6. Testing & verificationEnergize the new circuit by turning on the new breaker. Use a non-contact tester at the outlet to confirm the circuit is hot before plugging anything in. Test the GFCI using the TEST button — confirm power is interrupted at the outlet face. Press RESET to restore power. Use a plug-in outlet tester (3-light type) to verify correct hot, neutral, and ground polarity and confirm no open ground or reversed wiring. Measure voltage at the outlet under load using a multimeter — voltage should be between 115 and 125V. Record voltage reading in the job documentation.
7. Inspection, labeling & closeoutSchedule the required rough-in and final electrical inspection with the AHJ. Have the permit card on site for the inspector. Label the new breaker in the panel directory with the circuit description (e.g., 'Kitchen Counter — North Wall'). Repair all drywall openings made during installation. Photograph the completed outlet, the panel with the new breaker labeled, and all visible cable runs. Provide the customer with the passed inspection paperwork and explain GFCI test frequency (monthly) and reset procedure.
