Outlet Load Calculator

Audit one documented connected-load VA schedule against a source-labelled capacity basis and explicit percentage—without converting watts, selecting a breaker/circuit or declaring overload/compliance.

Use this result well

Inputs that matter
One de-identified reviewed connected-load schedule; named load and capacity sources; an already documented VA capacity and copied capacity percentage; and one through three complete groups with whole simultaneous quantity, VA per item and explicit multiplier
Output to expect
Source-preserving group VA, connected-load total, entered applied capacity, signed VA difference and capacity-use arithmetic
How it works
Sum whole quantity x entered VA per item x only the entered group multiplier and compare with entered capacity x its entered percentage; do not convert watts to VA, infer 180 VA or 80%, select a breaker/circuit or declare overload/compliance
  • Confirm apparent-power values, power-factor/conversion basis, simultaneous quantities and each group/capacity multiplier against the responsible calculation and equipment data.
  • Verify receptacle allowances/count treatment, continuous and demand loads, dedicated/special circuits, voltage/phase, conductor, protection, AFCI/GFCI, adopted requirements and AHJ acceptance separately.

Choose your path

Built around the job you need to finish

Reproduce one source-labelled connected-load VA schedule against an already documented capacity basis and percentage without converting watts, selecting a circuit or declaring overload/compliance.

Electrical designer auditing a plug-load schedule

Sum explicit item groups without a generic form silently assigning 180 VA, 80% or one circuit treatment.

Name the load and capacity sources, copy up to three complete groups and inspect applied capacity versus connected total.

Can trace every VA and multiplier while circuit/protection selection remains in the complete design.

Plan reviewer checking provenance

Distinguish apparent-power schedule arithmetic from watts, breaker capacity and a compliance conclusion.

Inspect source cards, whole quantities, VA-per-item values, both multiplier levels and the signed difference.

No W-to-VA assumption, available-watts claim, overload label or upgrade instruction is generated.

Apprentice comparing connected-load records

Learn why receptacle allowance, simultaneous equipment and continuous-load treatment cannot be inferred from a generic outlet count.

Run separate education records with explicit source-owned group and capacity percentages.

Can reproduce the arithmetic and list dedicated-circuit, conductor, protection and authority checks the tool omits.

Reference & details

How it works

Keep Load and Capacity Sources Separate

The connected-load schedule owns item quantities, apparent-power values and group multipliers. The separate responsible calculation owns the capacity basis and applied percentage; neither is inferred from a breaker label.

Record = connected-load source + capacity source

Reproduce Group VA

Every group keeps its own name and source-owned multiplier. The tool never treats watts as VA, assigns 180 VA by outlet count or invents diversity/continuous-load treatment.

Group VA = whole simultaneous quantity × entered VA per item × entered multiplier

Read Capacity Difference as Arithmetic

Positive, zero or negative results are signed arithmetic only. They do not establish available watts, overload, circuit rating, dedicated-circuit requirements, conductor, protection or approval.

Difference = entered capacity × entered % − connected-load total

Example Scenarios

A reviewer copies workstation and printer groups in VA from an approved schedule, plus the separately documented applied capacity. The tool exposes group and total arithmetic without approving the circuit.

A designer uses measured or documented apparent-power values and explicit simultaneous quantities from a reviewed record. Watts, nameplate data and power factor must be reconciled by that source before entry.

An apprentice runs separate de-identified records with copied group/capacity percentages. A negative difference becomes a question for responsible review, not an automatic overload or upgrade instruction.

FAQ

No. Receptacle allowances and counting rules depend on the controlling calculation and occupancy/application. Copy the exact VA per item and quantity from the named source.

Not unless the responsible source documents the conversion or equivalence for that equipment and condition. Apparent power can differ from watts because power factor and operating state matter.

The applicable treatment can depend on continuous/noncontinuous loads, listings, equipment and adopted requirements. The tool does not insert a universal 80% factor.

No. It is a VA arithmetic difference against the entered capacity basis. It does not verify operating current, power factor, circuit rating, equipment behavior or installation suitability.

No. Dedicated/special circuit rules, conductor and breaker selection, AFCI/GFCI, voltage/phase and final approval require the complete adopted design and authority review.

About Outlet Load Calculator

Reproduce the arithmetic in one reviewed connected-load record. Name the load and capacity sources, copy the already documented VA capacity and percentage, and enter up to three complete item groups with whole simultaneous quantity, VA per item and explicit multiplier. The result is an audit record, not a circuit-layout or protection decision.
