Technical documentation for the Leviton G5USB identifies it as a hard-wired safety component with an integrated DC power stage. The unit features a 4.8A (24W) shared USB capacity and a proprietary self-test GFCI algorithm exceeding UL 943 standards. Material analysis confirms the use of heavy-duty brass contacts and high-grade electrolytic capacitors for the DC rectification stage.
Performance metrics indicate that the GFCI sensing coil is physically isolated from the high-frequency USB transformer to prevent nuisance tripping caused by EMI. While the unit is a "shallow-depth" design relative to its features, it still requires a 2.5-inch junction box for optimal wire management. The USB-C ports provide 5V delivery but do not support high-voltage Power Delivery (PD) handshakes.
For installations requiring a 20A branch circuit rating, the Suplevel 20A GFCI combo offers a higher continuous load capacity for workshop environments.
This device is a specialized safety node within the in-wall USB smart outlets classification, combining protection with DC power.
