Review actual bathroom protection requirements, map physical devices and downstream outlets, then record installation checks and dated test results.
Draw the bathroom and list receptacle locations, fixed equipment and proposed changes. Confirm the adopted requirements for the project, including circuit supply, receptacle placement, GFCI protection and any other applicable protection or device properties. Record the reviewing authority or installer and keep uncertain requirements open.
Choose a manufacturer-supported protection arrangement with the installer. Assign a physical device ID and circuit ID, then map every outlet it is intended to protect. Distinguish the GFCI receptacle itself from downstream outlets and ensure access for required testing and reset. Record the exact device model and instructions.
Have the installer review equipment nameplates, actual intended loads and the applicable bathroom branch-circuit rules. Where a generic continuous-load calculation applies, compare the actual breaker catalog with the verified conductor/equipment ceiling. Screen conductor candidates only under documented installation and terminal conditions.
Mark actual receptacle positions, device access and the specified cable route on the plan. Confirm the exact location restrictions and circuit arrangements with the installer; the ordinary wall-span spacing tool is not a substitute for bathroom-specific placement rules. Compare installed scopes including devices, boxes, wall repairs, permits and testing.
Have the authorized installer complete isolation, connections and verification using the exact device instructions, including line/load identification and any required electrical tests. After safe completion, operate the prescribed test/reset controls and verify interruption at every intended protected outlet. Record failed or untested locations explicitly and have problems corrected.
Save the installed device IDs, circuit mapping, test dates, test results and manufacturer instructions. Provide occupants with accessible test/reset information and the installer’s contact. Follow the manufacturer’s routine and retest after relevant changes or events; keep the portable export alongside the local browser record.
Map physical GFCI devices to same-circuit outlets and record each required outlet’s actual downstream test result; keep unknown requirements and failures visible.
Keep the dated equipment list, document references, responsible installer and unresolved decisions; export the record with the calculation cases.
Select only from the exact approved breaker catalog using noncontinuous and weighted continuous current plus the verified protection ceiling.
Screen the finite manufacturer chart using required ampacity, the actual breaker, correction factor and limiting terminal column; review every failed condition.
Record each circuit’s reviewed AFCI requirement and planned physical breaker or approved alternative method; count unique assemblies and resolve unknown decisions.
Count actual continuous cable runs, specified cable type, slack and parallel cables, then allocate usable stock rolls; the tool does not produce a wiring diagram.
Compare actual installed quotes, deposits, chosen contingency and confirmed reimbursements; retain the scope and date of each case.
Loading your checklist…
Correct device connections and actual downstream tests establish the recorded coverage. A room-level quantity estimate cannot establish it.
AFCI addresses certain arc faults; GFCI addresses ground-fault shock hazards. Applicable requirements and supported equipment must be reviewed for the actual project.
Use the actual cable rules and terminal ratings for the specified circuit rather than a fixed AWG recipe.
Keep an understandable map so an occupant can find the device protecting a particular outlet.
An outlet can pass a test while its required device type or placement still needs review.
