calculate_voltage_drop — Use for branch circuits, feeders, long runs, copper/aluminum voltage drop, one-way length, single-phase, and three-phase voltage drop questions.
calculate_wire_size — Use for wire sizing, ampacity derating, continuous load checks, terminal temperature limits, NEC/CEC conductor sizing, and EGC upsizing notes.
calculate_box_fill — Use for device box cubic-inch checks, conductor allowances, grounds, NEC clamps/supports, CEC wire connectors, fixture studs/hickeys, and device/yoke counts.
calculate_dwelling_load — Use for residential service sizing, standard and optional dwelling load methods, EV loads, HVAC comparison, ranges, dryers, and future growth.
calculate_motor_flc — Use for motor full-load current, conductor sizing at 125 percent of FLC, and inverse-time breaker/OCPD sizing questions.
calculate_electrical_formulas — Use for formula questions where the user asks for three-phase kW/kVA, energy cost, Ohm's law-style helper math, or electronics reference calculations.
calculate_short_circuit — Use for point-to-point available fault-current screening, conductor run reduction, and interrupting-rating planning.
calculate_arc_flash — Use for arc-flash awareness screening with fault current, clearing time, working distance, equipment type, and electrode configuration.
