How it works

GFCI device and downstream coverage record

Map actual outlets to physical GFCI devices and retain each outlet's reviewed requirement and observed test result. One properly installed device can protect multiple downstream outlets; room count does not determine device or circuit count. Keep uncertain locations explicitly unresolved.

Count unique physical GFCI devices separately from outlets; a required outlet is recorded covered only when its mapped device exists on the same circuit and the outlet test is recorded passed.

Map actual outlets to physical GFCI devices and retain each outlet's reviewed requirement and observed test result. One properly installed device can protect multiple downstream outlets; room count does not determine device or circuit count. Keep uncertain locations explicitly unresolved.

Use the exact equipment, dimensions, current ratings, operating conditions and applicable requirements described in the selected mode. Unknown values are not replaced by a generic wire, device count or capacity. Illustrative examples are arithmetic examples, not an approved installation.
