## Key Features

- **Equipment Grounding Conductor (EGC) Calculator**: Sizes EGCs per NEC Table 250.122 for OCPD ratings ranging from 15A to 6000A with support for copper and aluminum.
- **Voltage Drop Adjustment**: Automatically calculates proportional EGC increases when circuit conductors are upsized per NEC 250.122(B).
- **Grounding Electrode Conductor (GEC) Tool**: Determines GEC sizes based on NEC Table 250.66, including specific sole-connection exceptions.
- **Bonding Jumper Calculator**: Calculates bonding jumpers per NEC Table 250.102(C)(1) utilizing the 12.5% rule for parallel service conductors.
- **Offline Functionality**: Designed for full operational capability without an internet connection, making it suitable for remote job site environments.
