# Division 26: Electrical submittal deviations > Source: https://deviationcheck.com/divisions/26-electrical/ > Deviation Check - AI submittal review for General Contractors (Aliso LLC). Division 26 covers electrical systems in commercial construction: power distribution, lighting, communications raceways, grounding, overcurrent protection, wiring devices, and related equipment.

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 Full guide: https://deviationcheck.com/divisions/26-electrical/manufacturer-substitution/ ### Performance Specification Gap (default grade: Blocker) A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires. 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 Full guide: https://deviationcheck.com/divisions/26-electrical/performance-specification-gap/ ### Missing Certification or Compliance Documentation (default grade: Fix and Resubmit) A required listing, test report, certification, or compliance document is absent from the submittal package. Required certifications in electrical submittals: - **UL listing** (or ETL/CSA equivalent) - required for nearly all electrical equipment; absence is always a blocker - **NEMA standards compliance** (NEMA 1-13 for enclosures, NEMA MG-1 for motors) - **NEC (NFPA 70) compliance** statement - **IEEE test reports** (C57 for transformers, 1584 for arc flash) - **DLC (DesignLights Consortium)** qualification for commercial lighting - **Energy Star** certification where spec requires - **Buy America / Buy American** compliance (federal/state funded projects) - **Seismic certification** (IBC, OSHPD for California hospitals) for equipment anchorage - **ASHRAE 90.1** compliance documentation for energy-consuming equipment - **Short-circuit and coordination study** data sheets - **Factory test reports** for switchgear, generators, UPS systems Full guide: https://deviationcheck.com/divisions/26-electrical/missing-certification/ ### Aesthetic Deviation (default grade: Fix and Resubmit) A visible attribute (color, finish, texture, profile) differs from the spec or the architect-approved sample. Less common in electrical but applies to: - Lighting fixture finish color (white, black, bronze, custom RAL) - Switchplate and device cover colors - Panelboard door finish - Exposed conduit finish (where architecturally exposed) Full guide: https://deviationcheck.com/divisions/26-electrical/aesthetic-deviation/ ### Detail or Installation Mismatch (default grade: Fix and Resubmit) The submitted detail, dimension, anchorage, or installation method differs from what the spec or drawings require. - **Wire sizing** different from spec (e.g., spec calls #10 AWG, submittal shows #12 AWG) - **Conduit type** mismatch (EMT vs rigid vs flexible, spec may require specific type in certain locations) - **Mounting height** for devices differs from spec or drawings - **Circuit breaker trip curve** type (thermal-magnetic vs electronic trip) - **Grounding method** (separate ground conductor vs metallic raceway) - **Seismic bracing** method differs from spec - **Connection type** (bolted vs compression vs set-screw) - **Surge protection** location or rating differs Full guide: https://deviationcheck.com/divisions/26-electrical/detail-installation-mismatch/ ### Submittal Package Incompleteness (default grade: Fix and Resubmit) A required submittal element (cut sheet, schedule, calculation, sample) is missing, leaving the package unreviewable as submitted. Commonly required items in Div 26 specs: - Single-line diagrams - Panel schedules with circuit assignments - Equipment nameplate data / catalog cut sheets - Wire and cable schedule - Lighting fixture schedule with photometric data (IES files) - Load calculations - Short-circuit study results - Arc flash labels / study - Coordination study (time-current curves) - Seismic anchorage calculations - Warranty documentation - O&M (Operation and Maintenance) manuals --- Full guide: https://deviationcheck.com/divisions/26-electrical/submittal-package-incompleteness/ ## How Division 26 deviations are graded - **Any SCCR or AIC rating below spec requirement:** Always BLOCKER (life-safety - explosion/fire risk) - **Voltage mismatch:** Always BLOCKER (equipment damage, electrocution risk) - **Missing UL/ETL listing:** Always BLOCKER (NEC requirement, code violation) - **Wire gauge undersized vs spec:** BLOCKER (fire risk per NEC) - **NEMA enclosure rating lower than spec:** BLOCKER if outdoor or wet location, FIX_AND_RESUBMIT if indoor dry location - **Missing arc flash study:** BLOCKER (OSHA/NFPA 70E compliance) - **Lighting CCT or CRI mismatch:** FIX_AND_RESUBMIT (aesthetic, not safety) - **Missing DLC listing for lighting:** FIX_AND_RESUBMIT (energy code compliance, not life-safety)
