Home Generator and Transfer Planning

Compare actual running W/VA and simultaneous starting events with generator continuous, temporary and duration ratings; show candidates that fit.

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

Compare actual transfer-switch normal and generator current-path ratings with a documented service or selected-load design and save the basis.

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

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

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

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

Simple in-browser notepad with auto-save. Write quick notes that persist in your browser. Download as text file. No signup needed.

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

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

Model an isolated vertical rod in homogeneous soil, explore a bounded target depth and compare actual tests with uncertainty and a chosen threshold.

Generate positions on actual eligible wall spans, then check measured receptacle coordinates for uncovered gaps using a documented reach rule.

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.

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