Reconcile documented split-phase demand categories and per-leg current, then count actual panel spaces and circuits in a separate inventory.

Check configured EVSE AC current against ordinary circuit limits, then estimate charging energy and time using vehicle acceptance and efficiency.

Count unique planned AFCI and dual-function breakers from reviewed circuits, retaining approved alternative protection and unresolved decisions.

Map actual GFCI devices and downstream outlets, record tests and expose unknown requirements without inventing circuit or device counts from rooms.

Compare copper and aluminum chart sizes using required ampacity, correction factors, terminal ratings and protection limits; save the full basis.

Compare documented feeder ampacity and actual AC impedance, recalculate voltage drop for every conductor and identify when no candidate fits.

Compare actual breaker catalog ratings with weighted circuit current and verified conductor or equipment limits; identify when no candidate fits.

Calculate DC path drop or approximate single-phase and balanced three-phase AC drop using actual conductor data, circuit current and a chosen limit.

Build an installed quote, compare lifetime costs and calculate material packs. Separate payment-day cash from later reimbursements using your project records.

Plan continuous cable cuts from a specified circuit route, actual slack and parallel cable counts, then allocate stock rolls and quoted cost.

Plan a centered grid from luminaire spacing criteria and height above the work plane; get fixture counts, pitch, offsets and actual coordinates.

Check actual lamp or driver W/VA, load range, lamp counts and compatibility against the exact dimmer’s documented load-type and ganging limits.

Allocate indivisible lighting groups to proposed circuits using actual input VA and continuous-load weighting; show a feasible plan or oversized groups.

Compare mixed insulated conductors or cables with full raceway internal areas; apply the ordinary count-based fill limit once and screen candidates.
