Electrical Load Calculator. Reproduce one source-labelled electrical load schedule from connected volt-amperes and explicitly copied line multipliers—without choosing code factors or sizing a service, feeder, conductor or breaker.
Choose your path
Reproduce one source-labelled electrical load schedule from explicit connected-VA lines and copied multipliers without selecting code factors or sizing a service, feeder, conductor or overcurrent device.
Check arithmetic without a generic form silently assigning demand factors or a 240 V service assumption.
Name the schedule and multiplier sources, copy up to four complete VA lines and inspect connected versus multiplied totals.
Can trace every line while the complete adopted-code calculation and design decisions remain external.
Distinguish entered worksheet arithmetic from a complete NEC/IRC/AHJ load calculation.
Inspect source cards, line names, each copied multiplier and the explicit no-service-sizing boundary.
No universal 75% factor, voltage, current, ampacity or approval claim is generated.
See multiplier arithmetic while learning that equipment classification and applicable tables must be established first.
Run separate education records, including a documented 125% multiplier, and compare the exposed line steps.
Can explain VA × entered percent and identify what the calculator deliberately does not decide.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
Tools you might need next
Audit one documented protection-selection record from source-labelled current components, an explicit multiplier, an already selected device rating, and a documented conductor ampacity—without choosing a breaker or declaring compliance.
Audit voltage-drop arithmetic for one source-selected candidate conductor using documented impedance, path and units—without selecting AWG, ampacity, an allowable drop or code compliance.
Audit one documented series circuit path from source-labelled segment currents, lengths, path multipliers and effective impedances—without assuming copper, choosing wire size or applying a pass/fail threshold.
Copy volt-amperes from the responsible schedule. Watts and VA are not automatically interchangeable; any power-factor or conversion method must be documented outside this tool.
Connected total VA = Σ entered line VAThe same numeric factor is not valid for every load class. Current NFPA material applies 75% only under defined appliance conditions and excludes several equipment categories.
Line schedule VA = connected VA × entered multiplier ÷ 100A complete adopted-code calculation can require other loads, tables, noncoincident choices, voltage/phase and local rules. This output does not determine amperes, service rating, conductor or protection.

Enter four exercise-stated VA lines and their explicit 75/75/100/75 multipliers. The 8,525 VA result reproduces the exercise only; it is not a recommended residential factor set.
A responsible worksheet may supply a multiplier above 100%. Enter 125% only when the named source explicitly owns that value; the calculator does not decide when it applies.
Reproduce selected lines from a reviewed existing-load worksheet while retaining the worksheet source. Capacity for the alteration still requires the complete calculation and authority review.
Audit one de-identified load schedule without hidden electrical assumptions. Name the connected-load and multiplier sources, then enter one through four complete VA lines. The result reproduces only those line multipliers and does not create a code-complete service calculation.
