Schneider Electric Homeline HOMCRBGK1C Generator Interlock Kit for 100–125A QOM1 Main, Outdoor NEMA 3R

This outdoor-rated interlock kit is designed for Homeline "S" Series load centers (NEMA 1 and NEMA 3R) and mechanically prevents the main service breaker and a generator-fed 2‑pole branch breaker from being on at the same time. It allows you to backfeed a generator through a Homeline branch breaker (15–125A) while ensuring service isolation, and it includes labels and wiring guidance to simplify installation and inspection.

How does this interlock kit maintain safety when using a portable generator?

The kit creates a physical lockout between the QOM1 main breaker and the designated 2‑pole generator breaker so both cannot be closed together. That prevents accidental backfeed to utility lines and protects utility workers and equipment.

• Mechanical interlock prevents simultaneous main and generator breaker engagement.
• Designed for QOM1 2‑pole mains (100–125A)
• Works with Homeline 2‑pole branch breakers rated 15–125A for generator feed.
• UL listed and ANSI certified for recognized safety standards.

Will this kit fit my outdoor Homeline load center?

Yes, the HOMCRBGK1C is made for Homeline "S" Series load centers in both NEMA 1 (indoor) and NEMA 3R (outdoor) enclosures, provided the panel uses a QOM1 main breaker. Confirm your load center model and main breaker type before purchase.

• Compatible with Homeline "S" Series load centers.
• Specifically interlocks QOM1 2‑pole mains (100–125A).
• Intended for single main breaker panels with space for a 2‑pole branch breaker backfeed.
• Includes labels and wiring diagram to match installation needs.

What installation details and accessories are included?

The kit ships with the interlock hardware, translation labels, and a wiring diagram so electricians and qualified installers have the documentation needed for correct mounting and inspection. No separate generator subpanel is required, which can save space and cost.

• Interlock brackets and hardware matched to Homeline dimensions.
• Wiring diagram for correct breaker placement and connections.
• Interlock translation labels for compliance and inspection.
• Outdoor-compatible components for NEMA 3R installations.

How do I choose the right breaker sizes when using the interlock?

Select a Homeline 2‑pole branch breaker sized for the generator output and the circuits you intend to run; the interlock supports branch breakers from 15A up to 125A. Ensure the breaker and wiring match the generator's rated amperage and local electrical codes.

• Branch breaker range supported: 15–125A (2‑pole).
• Match breaker ampacity to generator continuous and peak ratings.
• Verify conductor sizing and overcurrent protection per code.
• Hire a licensed electrician for safe, code-compliant installation.

Who is this for: The HOMCRBGK1C interlock kit is for homeowners and contractors who want a compact, code-friendly way to power selected circuits from a portable or standby generator without adding a separate generator panel. It's ideal for installations using Square D Homeline "S" Series load centers with a QOM1 main breaker (100–125A) and for anyone prioritizing mechanical safety, outdoor compatibility, and clear installation documentation.
