What it is: A new sub-feed lug block designed for Eaton panels. Best for Eaton customers needing a direct lug block upgrade to support additional feeds.
Best for: Electricians or homeowners with Eaton panels seeking a straightforward lug-block replacement to expand sub-feed capacity. It’s selected for its standard compatibility with Eaton’s lug block family.
Why chosen: This unit provides a clean, factory-specified method to add sub-feed capacity without altering the panel’s internal layout. It aligns with Eaton’s design language and mounting footprints.
Caution: Confirm panel model compatibility with Eaton’s support documentation before purchase to avoid fit issues.
225A LUG KIT
What it is: A 225A lug kit designed to support higher feed capacity in compatible panels. Best for mid-range expansion needs in residential or light commercial settings.
Best for: Homeowners or pros upgrading panel feeders that require more robust lug connections without replacing the entire enclosure.
Why chosen: The kit targets higher amperage while staying within common lug configurations, making it convenient for standard 225A panels.
Caution: Verify warranty terms and ensure the kit matches your panel’s lug pattern and terminal layout.
#MBK200 200 Amp 2-Pole Main Breaker Conversion Kit
What it is: A 200A two-pole main breaker conversion kit for Siemens EQ load centers. Best for converting a main lug center to a main breaker center without significant rewiring.
Best for: Installers working with Siemens EQ panels needing a seamless replacement to add main protection. It supports typical residential and small commercial loads.
Why chosen: It provides a direct replacement path, and the listed specs indicate compatibility with Type EQ9685. This can simplify upgrades in compatible Siemens panels.

Buying Guide: Key Considerations for 200 Amp Sub Feed Lug Kits
What amperage is right for my panel?
Choose a lug kit that matches or exceeds the panel’s bus rating and the desired sub-feed load. Oversizing beyond the panel’s tolerance can create unsafe conditions; undersizing can limit future expansion.
Compatibility with panel brand and model
Stick to kits designed for your panel brand (Eaton, Siemens, etc.) and model family. Cross-brand compatibility may be limited and could void warranties or violate codes.
Type of installation
Decide between lug blocks for direct sub-feed access or main-breaker conversion kits. Main-breaker conversions add protection at the panel entry point, while lug blocks typically extend feeder capacity without replacing the main breaker configuration.
Wiring and conductor requirements
Check conductor size ranges (AWG) supported by the lug kit. Ensure the allowed wire sizes match your feeder conductors and comply with local electrical codes.
Warranty and support
Look for a solid warranty and manufacturer support. A longer warranty can indicate confidence in long-term performance, but verify what is covered and for how long.
Installation considerations
Confirm that the lug kit’s mounting and footprint align with your panel’s interior layout. Some configurations require additional hardware or professional installation to maintain code compliance.
Safety and codes
All work should meet local electrical code requirements and may require a licensed electrician for installation. Improper installation can lead to overheating, arcing, or failed inspections.
FAQ
- Q: Can I mix lug kits from different brands?
A: It is not recommended. Use kits designed for your specific panel brand and model to ensure safe, compliant installation. - Q: Do lug kits require rewiring the entire panel?
A: Not necessarily. Some kits simply add sub-feed capacity or convert to a main breaker center, depending on the kit type. - Q: Is a higher amperage lug kit always better?
A: Not always. Choose based on your panel’s rating and anticipated load to avoid exceeding the panel’s design limits. - Q: Should I hire an electrician for installation?
A: Yes. Sub-feed and main-breaker conversions involve critical safety contexts and must comply with code requirements. - Q: How can I verify compatibility with my panel model?
- Q: Are there limitations with 225A lug kits?
A: Some kits are rated for 225A but may require specific panel types or hot-short-term protection considerations; always verify with the manufacturer.
A: Check the panel’s model number, refer to the manufacturer’s compatibility guides, and compare mounting patterns and terminal arrangements before purchasing.
