Electrical Engineering Toolboard
A working panelboard for the calculations I run all the time — each tool is its own feeder breaker, one click to open it. New feeders get added over time, and existing ones keep getting refined.
Calculates fill ratio from tray specs and circuit schedule, checks against code-allowed occupancy, with metric/imperial toggle and a design title block.
Checks feeder voltage drop under CSA C22.1 — enter system voltage, conductor size and run length to see if it clears the allowed percentage.
Plant-wide electrical load allocation as a single-line overview — shows distribution branches and load spread, with sizing recommendations.
Cable selection and protective device setup for small dry-type transformers — primary/secondary conductor sizing plus overcurrent protection settings.
Reserved slot — new calculation tools will be wired into this panel over time.
