NEMA 5-20R GaN Dual USB-C Fast Charging Receptacle
- 20A NEMA 5-20R receptacle format for properly matched commercial branch-circuit applications
- Two pure USB-C ports support modern charging deployment without a legacy USB-A port
- Either USB-C port can deliver up to 36W Power Delivery when used on its own
- Maximum combined USB output is 36W, with dynamic sharing when both Type-C ports are used

20A Circuit Rules and Dual USB-C Output
A 20A 36W GaN dual USB-C receptacle is not a general-purpose upgrade for any wall box because it combines a NEMA 5-20R commercial branch-circuit format with a charging configuration aimed squarely at modern Type-C device ecosystems. This model keeps the AC side at 20A / 125V and replaces mixed-port charging with two USB-C ports, where either port can deliver up to 36W Power Delivery when used alone and the total USB output is capped at 36W across both ports. UL / cUL positioning, tamper-resistant shutters, and a non-GFCI indoor dry-location design make this SKU suitable for executive workstations, meeting rooms, libraries, and other specification-driven interiors that want both 20A receptacle compatibility and cleaner desk-level charging. This page needs separate treatment because 20A circuit matching, pure Type-C deployment, and shared-power behavior create a very different purchase decision from 15A models or hybrid USB-A/C alternatives.
Who Should Use This Model
- Contractors sourcing a 20A NEMA 5-20R USB receptacle for code-matched commercial branch circuits
- Facility teams upgrading executive boardrooms, airport workstations, libraries, and tech-forward shared spaces
- Distributors serving buyers who want dual USB-C deployment instead of mixed old-and-new charging ports
- Project purchasers who need a 20A T-slot format plus stronger tablet and lightweight laptop charging support
When to Choose a Different Model
- Choose a 15A dual USB-C model when the project uses standard NEMA 5-15R applications rather than 20A circuit compatibility
- Choose a hybrid USB-A/C receptacle when the site still needs to support legacy USB-A charging cables
- Choose a USB GFCI model when the installation is near sinks, breakroom wet zones, bathrooms, kitchens, or other locations requiring ground-fault protection

Frequently Asked Questions (FAQ)
Can a 20A dual USB-C receptacle be installed on a 15A branch circuit?
No. NEC 210.21(B)(3) does not permit a 20A receptacle to be installed on a 15A branch circuit. This model uses a NEMA 5-20R configuration and should be matched to the correct 20A application.
Will either USB-C port charge a laptop?
Yes, for some lightweight laptop models. Either USB-C port can provide up to 36W Power Delivery when used alone, which is suitable for many tablets and lighter notebooks, but it is not intended for larger laptop platforms that normally require 65W or more.
What happens when both USB-C ports are used at the same time?
The total available USB output is shared within a 36W maximum combined limit. When both Type-C ports are active, the receptacle dynamically distributes power across the two devices instead of supplying full 36W output to each port simultaneously.
Why choose a pure dual USB-C receptacle instead of a hybrid USB-A/C model for a commercial build?
A pure dual USB-C receptacle is better for projects that want to standardize around current charging habits rather than carry a legacy USB-A port into the wall. This format makes more sense in newer offices, boardrooms, and shared workspaces where users already rely heavily on Type-C cables.
Is this a GFCI receptacle for breakrooms, kitchens, or sink-adjacent areas?
No. This is a standard non-GFCI receptacle for indoor dry locations. Areas that require ground-fault protection should use a GFCI or USB GFCI device instead.
Do tamper-resistant shutters matter on a commercial dual USB-C receptacle?
Yes. Tamper-resistant construction is an important code and safety feature for many covered installation types under NEC 406.12. This model includes TR shutters as part of its specification profile.
Does a 20A high-output dual USB-C receptacle usually need a deeper wall box?
Yes. A device that combines 20A receptacle hardware with dual Type-C charging electronics and higher PD output usually needs more installation space than a basic outlet. Installers should evaluate box depth, conductor volume, and NEC 314.16 box fill planning before specifying this SKU.
Where is this model a better fit than a lower-output USB receptacle?
This model is a better fit for executive boardrooms, libraries, airport workstations, coworking zones, and similar dry indoor spaces where users may charge tablets or lightweight laptops, not just phones. It also makes more sense when the buyer needs both a 20A NEMA 5-20R receptacle format and a pure Type-C charging strategy.

5-Step Quick Wiring Guide
Follow standard U.S. wiring protocols. Always verify power is off before installation.
- Power Off & Verify: Turn off the breaker and verify the box is de-energized with a voltage tester.
- Identify Conductors: Locate the Black (Hot), White (Neutral), and Bare/Green (Ground) wires.
- Connect Ground: Secure the bare copper or green wire to the Green grounding terminal.
- Connect Neutral & Hot: Connect the White wire to the Silver terminal, and the Black wire to the Brass terminal.
- Mount & Test: Fold wires neatly into the box, mount the receptacle, install the wall plate, and restore power to test.
