Feature → Business Impact → Application: High-current copper bus, 2000A rating improves electrical reliability and reduces thermal losses, enabling efficient distribution for heavy feeders in industrial facilities. This supports uptime targets and lowers cooling costs in high-load environments. Application: main feeder trunks feeding large downstream panels in manufacturing plants or data centers. Feature → Business Impact → Application: NEMA 3R outdoor/indoor enclosure provides weather-resistant protection, reducing the risk of moisture ingress and corrosion in outdoor locations. This minimizes maintenance cycles and extends service life for installations exposed to the elements. Application: exterior electrical rooms and outdoor equipment closets with frequent exposure to rain or dust. Feature → Business Impact → Application: Top/bottom feed and three-wire single-phase configuration simplifies field wiring, accelerating installation and reducing labor time while maintaining compliance with common electrical codes. Application: service entrances and main distribution points in commercial and industrial facilities. Feature → Business Impact → Application: Large conductor accommodation (8 × 750 kcmil or 16 × 1/0–300 kcmil) supports substantial load capacity with flexibility for future expansion, reducing the need for rework. Application: upstream feeders to large motor loads and critical process lines. Feature → Business Impact → Application: 32.88 in × 60.14 in × 17.39 in footprint and 250 lb weight offer a rugged, space-conscious solution that can be integrated into tight rooms or retrofit projects. This improves layout planning and serviceability. Application: plant-wide main terminations where space and access are constrained. Feature → Business Impact → Application: UL Listed certification reinforces compliance readiness for electrical assemblies, helping with regulatory approvals and reducing audit risk. Application: new builds and upgrade projects in manufacturing, with stringent safety and quality expectations.

FAQs
The 1MTB2000RC supports top or bottom feed configurations for a three-wire, single-phase system and accommodates conductor sizes of (8) 750 kcmil or (16) 1/0–300 kcmil. This enables flexible routing from a main service disconnect to downstream panels while maintaining full 2000A capacity.
Yes. The unit features a NEMA 3R enclosure, designed for outdoor and underground service environments. This provides weather and ingress protection, reducing maintenance needs and enabling reliable operation in exposed areas.
The terminal box is UL Listed, ensuring compliance with recognized safety standards. This certification supports regulatory approvals, quality assurance, and smoother acceptance during audits and commissioning.
Plan for a 120/240V, single-phase distribution path with top/bottom feed routing, ensuring space for the 32.88 in depth, 60.14 in height, and 17.39 in width. Confirm conductor counts align with the (8) 750 kcmil or (16) 1/0–300 kcmil capacity and verify room for future expansion if needed.
The product carries Eaton's warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. This aligns with typical industrial equipment expectations and helps mitigate maintenance and replacement costs over the initial years of operation.
