LoadBank Calc
iOS Universel / Utilitaires
LoadBank Calc is a fast, offline electrical panel load calculator for electricians and engineers. Calculate total connected loads, check NEC 80 percent continuous load rules, and manage circuit schedules with kW totals.
WHAT IT CALCULATES:
Panel Schedule:
- Add circuits with name, voltage, amperage, and breaker size
- See each circuit's kW load at a glance
- Track total connected load across all circuits
- Organize by branch circuit for clean panel documentation
Load Summary with NEC 80 Percent Rule:
- Total connected load in kW
- NEC demand load calculations per Article 220
- Panel utilization percentage with visual indicator
- Maximum continuous load based on panel ampere rating
- Clear PASS or FAIL status for the 80 percent rule
Circuit Entry:
- Enter circuit name, voltage, and amperage
- Select breaker size from standard ratings
- Choose load type: continuous or non-continuous
- Automatic VA and kW calculation
- NEC derated values for continuous loads
VOLTAGE CONFIGURATIONS:
- 120V single phase
- 208V single phase
- 240V single phase
- 208V three phase
- 480V three phase
KEY FEATURES:
