# Performance Specification Gap in Division 26 Electrical submittals

> Source: https://deviationcheck.com/divisions/26-electrical/performance-specification-gap/

A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires.

## What to look for in Division 26 Electrical

Key performance parameters in electrical submittals:
- **Voltage rating** (120V, 208V, 277V, 480V) - must match spec exactly
- **Ampacity / continuous current rating** - breakers, conductors, bus bars
- **Short-circuit current rating (SCCR)** - must meet or exceed spec; undersized SCCR is a life-safety blocker
- **Available Interrupt Current (AIC)** rating for breakers and fuses
- **NEMA enclosure rating** (1, 3R, 4, 4X, 12) - indoor vs outdoor, corrosion resistance
- **Efficiency ratings** for transformers (DOE 2016 compliant), motors (NEMA Premium), lighting (lumens per watt, DLC listed)
- **Color temperature (CCT)** and **Color Rendering Index (CRI)** for lighting
- **Wire gauge (AWG)** and insulation temperature rating (THHN, XHHW)
- **Conduit fill percentage** - NEC Article 310/366 limits
- **Arc flash incident energy** rating for PPE category compliance

## Severity

Default grade: Blocker. Always a Blocker when the gap touches life-safety or structural performance.
