What Is a 20A USB A/C Receptacle?
A 20A USB type A/C receptacle is a standard indoor wall outlet that combines a 20A, 125V, NEMA 5-20R AC receptacle with one USB-A port and one USB-C port. This model includes tamper-resistant shutters, 3.6A shared USB output at 5V DC, and a dry-location indoor design for everyday charging access without plug-in adapters. It is a practical choice for conference rooms, office upgrades, public waiting areas, and other commercial interiors that need both legacy USB-A and newer USB-C compatibility.
Who Should Use This Model
- Contractors sourcing indoor 20A USB wall outlet upgrades
- Office and commercial renovation buyers
- Facility managers upgrading conference rooms, lounges, and waiting areas
- Distributors building out hybrid USB A/C receptacle inventory for indoor dry-location projects
When to Choose a Different Model
- Choose a 20A USB GFCI receptacle when the installation location requires ground-fault protection, such as near sinks or other NEC-covered wet or damp locations
- Choose a 15A hybrid USB receptacle when the circuit and receptacle format do not require a NEMA 5-20R device
- Choose a PD or higher-output USB-C receptacle when the project needs faster charging than a 3.6A shared-output design

Frequently Asked Questions (FAQ)
Can I install this 20A hybrid USB receptacle on a standard 15A circuit?
No. NEC 210.21(B)(3) does not permit a 20A receptacle to be used on a 15A branch circuit. Because this device uses a NEMA 5-20R configuration, it must be installed on a correctly matched 20A branch circuit.
Does this 20A USB-C outlet include GFCI protection for wet areas?
No. This is a standard receptacle designed for dry indoor locations and it does not provide GFCI protection. Installations near sinks or other NEC-covered wet or damp locations should use a GFCI or USB GFCI model instead of this standard non-GFCI outlet.
What does a 3.6A shared output mean for this commercial USB outlet?
The USB-A port and USB-C port share a combined 3.6A output at 5V DC. A single device can draw up to 2.4A from one port; when two devices charge at the same time, the current is shared between both ports up to the 3.6A total. Actual charging speed depends on each device’s charging behavior.
Will the USB-C port fast-charge a laptop?
No. This model uses standard 5V USB charging and does not support laptop-class USB-C Power Delivery. Users should plug laptop AC adapters into the NEMA 5-20R receptacle slots and use the USB ports for phones, tablets, and other everyday portable devices.
Are tamper-resistant shutters necessary for a 20A commercial outlet?
Yes, in NEC-covered locations. Tamper-resistant construction is required for covered 15A and 20A nonlocking receptacles in locations such as dwelling units, hotel guest rooms, child care facilities, and other covered public-access settings. This model includes tamper-resistant shutters on the AC receptacle slots.
Does this USB receptacle require a special electrical box?
No special box type is required by default, but installers should confirm that the wall box has enough space for the device body and conductors. This receptacle installs in a standard single-gang wall box and uses standard 125V AC branch-circuit wiring.
Why choose a 20A USB A/C outlet over a 15A version?
A 20A USB A/C outlet uses a NEMA 5-20R configuration for projects that require a 20A receptacle format. It is the correct choice when the branch circuit and connected equipment call for a 20A-rated receptacle rather than a standard 15A NEMA 5-15R device.
Is this model weather-resistant?
No. This product is not a WR model and is intended for indoor dry-location use only. It should not be used as an outdoor or wet-location receptacle.
