Frequently asked questions
NEC recommends keeping continuous loads below 80% of panel capacity for safety and code compliance.
NEC compliance refers to adhering to the National Electrical Code, which sets safety standards for electrical installations.
The 80% limit ensures panels have a safety margin to prevent overheating and potential electrical failures.
Yes, input data for each panel separately to calculate individual loads.
While designed for commercial use, it can also be used for residential panels.
Regular checks are recommended, especially after adding new circuits or equipment.
Consider redistributing loads or upgrading the panel to handle increased capacity.

An electrical engineer needs to calculate the load on a 200A panel for a commercial building.
Sample input
- Total circuit load: 150A
- Panel capacity: 200A
Result
The current load is at 75% of the panel's capacity. This is within the NEC-recommended limit of 80%.
About Panel Load Calculator
The Panel Load Calculator is essential for maintaining electrical safety and efficiency in commercial settings. By calculating the load on an electrical panel, it ensures compliance with the National Electrical Code, which is crucial for preventing circuit overloads that can lead to failures or hazards. The tool is particularly valuable for engineers, facility managers, and contractors who need to ensure systems are not only functional but also safe and up to code. With precise calculations, users can confidently plan expansions, troubleshoot issues, or verify installations meet the necessary standards.
How it works
- Input total circuit load and panel capacity.
- The tool calculates the percentage of panel capacity used.
- Compare the calculated load against NEC guidelines.
- Provide feedback on load status and recommendations.
When to use it
- Electrical engineers assessing panel load during building design.
- Facility managers tracking electrical usage for compliance.
- Contractors ensuring panel installations meet regulations.
