Plan eligible wall spans and actual outlet coverage, coordinate circuits and conductor selection, then retain installation and protection-test records.
Draw the room with measured openings, fixed features, counters and intended use. Identify which wall or counter spans are subject to the applicable spacing rule and which features actually break a span. Confirm adopted code edition, local amendments, permit scope and who will perform and inspect the work before deciding a device count.
Generate a starting layout for each eligible span, then mark the coordinates on the real drawing. Adjust positions for accessible use, furniture, doors and the applicable mounting restrictions. Enter the actual proposed coordinates in the coverage mode and resolve every uncovered interval before the layout is accepted.
List intended loads and determine circuit assignment with the installation designer. Review receptacle type, rating, accessibility and applicable GFCI, AFCI, tamper-resistant or weather-resistant requirements for the actual location and work scope. Use circuit identifiers consistently across the layout, panel schedule and protection records.
Establish the completed design load and actual approved breaker family. Check permitted conductor ampacity using the installation method, insulation, terminals and correction factors, then compare the breaker candidates with the verified protection ceiling. Assess voltage drop using the selected conductor’s actual impedance and relevant load path.
Obtain a written scope covering devices, cable/raceway, boxes, wall repairs, permits and inspection. Have the authorized installer follow the exact product instructions and required isolation procedures, including verification of absence of voltage before conductor work. Retain required installation details such as approved device types and manufacturer torque values.
After the installation is safely completed, have operation, circuit identification and required electrical tests verified. Record GFCI protection at each intended downstream outlet using the exact device instructions, resolve failed or uncertain results and obtain required inspection approval. Save the final coordinates, circuit directory, device models and dated test record.
Enter only reviewed eligible continuous spans and the actual horizontal-reach rule; do not use a single perimeter with assumed door deductions. · Use Receptacle layout by eligible span, then Check actual receptacle coverage after moving any point; inspect per-span coordinates and uncovered intervals. · Run the coverage check on the final installed positions and save it with the measured drawing.
Keep the dated equipment list, document references, responsible installer and unresolved decisions; export the record with the calculation cases.
Map physical GFCI devices to same-circuit outlets and record each required outlet’s actual downstream test result; keep unknown requirements and failures visible.
Record each circuit’s reviewed AFCI requirement and planned physical breaker or approved alternative method; count unique assemblies and resolve unknown decisions.
Reconcile the documented demand categories and split-phase leg allocation; use the separate space inventory for actual device quantities and occupied positions.
Screen the finite manufacturer chart using required ampacity, the actual breaker, correction factor and limiting terminal column; review every failed condition.
Select only from the exact approved breaker catalog using noncontinuous and weighted continuous current plus the verified protection ceiling.
Use the AC mode with actual conductor R/X, operating current, length, phase arrangement and chosen equipment/design limit; evaluate relevant line-to-neutral paths separately.
Compare actual installed quotes, deposits, chosen contingency and confirmed reimbursements; retain the scope and date of each case.
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.
Total outside insulated-conductor/cable areas and compare full internal raceway areas using the ordinary count-based fill rule, applied once.

The ordinary dwelling wall rule measures along eligible unbroken wall space; wall countertops have a distinct horizontal-coverage rule. Determine eligibility and the adopted edition before using either value.
Use the applicable conductor/cable ampacity and terminal limits, then coordinate the protection rating and equipment instructions.
A GFCI can protect other outlets on its load side. Record the test at the intended protected outlet, not merely the existence of a nearby GFCI.
Use the same circuit and device IDs on the layout, panel schedule and protection record.
Include repairs, permits and testing so a cheaper material allowance is not mistaken for the whole installed cost.
