200A meter mains capability paired with a 120/240V single-phase service delivers robust feeder protection for typical residential loads and future expansion. The business impact is safer utility-grade service boundaries and simpler coordination with downstream breakers, reducing switchgear downtime. In practice, electricians install this unit at the service entrance to support reliable power delivery for single-family homes and small apartment buildings. UL Listed certification and a NEMA 3R enclosure meet code and weather-resistance standards. The business impact is compliance with electrical codes and reduced risk of weather-related failures. In outdoor applications or accessible meter enclosures, durable protection against moisture and corrosion is a key advantage. Aluminum bus construction lowers weight and improves corrosion resistance, yielding easier on-site handling and long-term maintenance savings. This translates to quicker installations and lower lifecycle costs. The five-jaw design with surface mounting ensures secure, high-conductor terminations for feeders using #6-350 kcmil, enabling reliable, scalable connections. The 10 kAIC interrupt rating provides high fault-current protection aligned with modern utility service levels, reducing fault-related downtime and enhancing overall system safety. Top/bottom feed capability adds installation flexibility, enabling retrofits into existing panels and streamlined commissioning across varied site layouts.

FAQs
MBXB200BTS is designed for residential service entrances with 120/240V single-phase systems. It supports top/bottom feed configurations and a five-jaw connection, enabling straightforward integration with common meter bases and existing service panels. Ensure conductor sizes align with #6-350 kcmil ground and feed conductors, and verify enclosure clearance for safe mounting.
A 10 kAIC interrupt rating indicates the breaker can interrupt fault currents up to 10,000 amperes, reducing the risk of arcing and component damage during short circuits. This aligns with utility-grade residential service requirements and supports safer service installations, particularly in areas with higher fault currents or longer feeder lengths.
Yes. The NEMA 3R enclosure provides weather-resistant protection suitable for outdoor or semi-exposed service entrances. UL Listed certification reinforces compliance with widely accepted electrical safety standards, making it appropriate for outdoor meter mains and protected indoor installations alike.
This meter mains unit is ideal for residential service entrances, new-build homes, and small multi-dwelling projects requiring reliable meter mains with aluminum bus conductors, top/bottom feed capability, and a compact footprint. Its single-phase 120/240V rating supports typical home electrical loads while meeting utility and code requirements.
The UL Listed, NEMA 3R-rated design with robust aluminum bus contributes to fewer field faults and longer service life. By reducing installation time with flexible feed options and high fault-ride protection, owners can lower labor costs during commissioning and maintenance, delivering a favorable total cost of ownership over the system’s life.
