FAQ
What is a UL 891 generator docking station?
A generator docking station is a permanently installed, UL 891-listed dead-front switchboard that provides a safe, tool-free connection point for temporary backup power. It eliminates improvised cabling during utility outages by using Series 16 cam-lock receptacles to connect portable or rental generators directly to your facility's distribution system. Learn more on our Generator Docking Stations page.
Can CODI generator docking stations be used for load bank testing?
Yes. CODI builds dual-purpose generator and load bank docking stations engineered to comply with NFPA 110 Section 8.4 requirements. These combined units allow critical facilities like hospitals and data centers to perform mandatory routine load testing on permanent standby generators and safely deploy temporary backup power using the exact same enclosure. View our system topologies and SLDs.
What electrical codes apply to temporary generator connections?
CODI generator docking stations comply with NFPA 70 (NEC) Article 408 for switchboard construction and wire bending space. They fulfill:
- NEC 700.3(F) & 701.12(G): Mandatory temporary connection means in emergency and standby power systems.
- NEC 406.13: Code-compliant support for single-pole separable interconnects (cam-locks).
- UL 891: Standard for dead-front electrical switchboards.
What are the maximum voltage and ampacity ratings for CODI switchboards?
CODI UL 891 switchboards are rated for low-voltage AC systems up to 600V nominal (1,000V maximum within UL scope), with continuous main bus ampacities ranging from 400A to 5,000A+. Short-Circuit Current Ratings (SCCR) are available from 65kAIC up to 200kAIC to match specific site fault current requirements. Configure your specs on our Switchboards page.
Does CODI force proprietary circuit breaker lock-in?
No. CODI utilizes an open-OEM architecture that accommodates molded-case and insulated-case circuit breakers from all major manufacturers. We routinely build with breakers from:
- Eaton
- Siemens
- ABB
- LS Industrial
This eliminates proprietary vendor lock-in, simplifies facility maintenance, and allows specifying engineers to match existing site hardware standards.
How do CODI switchboards address arc-flash safety?
CODI switchboards support NFPA 70E arc-flash risk reduction through integrated Energy-Reducing Maintenance Switching (ERMS) per NEC 240.87. Systems can be configured with Zone-Selective Interlocking (ZSI), maintenance mode switches, and infrared (IR) inspection windows for compliance-ready thermal scanning without opening live panels.
What is the difference between an MLO and an MCB panelboard?
An MLO (Main Lugs Only) panelboard terminates incoming conductors directly on the bus lugs and relies on an upstream device for main overcurrent protection, whereas an MCB (Main Circuit Breaker) panelboard includes an integral main breaker that functions as both primary overcurrent protection and a local disconnect. CODI builds custom UL 67 panelboards in both configurations from 100A to 1,200A. See options on our Panelboards page.
What enclosure ratings are available for CODI equipment?
CODI manufactures electrical enclosures to match any operating environment:
- NEMA 1 (Type 1): Indoor general-purpose electrical distribution.
- NEMA 3R / 3RX (Type 3R): Weatherproof outdoor enclosures rated against rain, sleet, and snow.
- NEMA 4 / 4X: Washdown-rated and stainless-steel enclosures for severe corrosive environments.
Why are CODI lead times faster than national catalog OEMs?
CODI manufactures and assembles 100% of its electrical distribution gear in Littleton, Colorado, bypassing the rigid backlog pipelines of national catalog manufacturers. Our vertically integrated fabrication—including in-house copper bus production, enclosure fabrication, and multi-brand component stocking—allows us to engineer, build, and ship custom low-voltage gear in a fraction of traditional OEM lead times.
Where is CODI Power Controls equipment manufactured?
All CODI Power Controls switchboards, panelboards, and generator docking stations are engineered, fabricated, and assembled in the USA at our 100,000 sq. ft. facility in Littleton, Colorado. We invite facility managers, contractors, and specifying engineers to visit our plant or review our manufacturing capabilities online.
