Electrical Circuit Utilization Analyzer — Rank Your Most Heavily Loaded Circuits
Compare several circuits at once and immediately see which ones consume the largest percentage of their entered rating.

Circuits to compare
Why utilization is useful
Comparing absolute current alone can hide the difference between circuits with different ratings. Utilization expresses each load as a percentage of its own entered capacity.
Example
A circuit carrying 12 A against a 16 A rating is at 75% utilization, while 12 A against a 20 A rating is 60%. The first circuit therefore ranks higher even though the current is identical.
Why rank circuits?
A fleet-level view helps maintenance and planning teams find where the largest modeled margins are being consumed rather than reviewing circuits in an arbitrary order.
What the threshold does
The threshold highlights circuits you may want to review under your chosen planning approach. It is intentionally user-controlled rather than presented as a universal electrical rule.
Limitations
The tool does not evaluate conductor condition, phase balance, protective devices, voltage drop, fault conditions, transient demand or local installation requirements.
Frequently asked questions
Can different circuit ratings be compared?
Yes. Each circuit keeps its own rating and is ranked by utilization percentage.
Does the top-ranked circuit need replacement?
No. Ranking simply identifies the highest modeled percentage for review.
Can I use measured loads?
Yes, provided you understand what operating condition and time period the measurement represents.
