# Manufacturer or Product Substitution in Division 26 Electrical submittals

> Source: https://deviationcheck.com/divisions/26-electrical/manufacturer-substitution/

The submittal proposes a different manufacturer or product than the spec names, without an approved or-equal or substitution request.

## What to look for in Division 26 Electrical

Electrical equipment specs frequently name manufacturers with specific catalog numbers (e.g., "Square D QO130, or approved equal"). Submittals often propose alternative brands (Eaton, Siemens, ABB, GE) without an approved equal letter. Look for:
- Switchgear, panelboard, and breaker manufacturer mismatches
- Lighting fixture manufacturer/model substitutions
- Generator and UPS equipment brand changes
- Motor starter and VFD (Variable Frequency Drive) manufacturer swaps

## Severity

Default grade: Blocker. Drops to a Note if the submittal attaches an or-equal approval letter from the architect of record.
