Siemens i2040l1200cu Main Lug Loadcenter 200A 120/240V

Product Description

The SIEMENS i2040l1200cu is a high circuit main lug loadcenter interior with neutral bar, designed for single-phase residential electrical distribution. Rated at 200 amps and 120/240 volts AC, this interior assembly provides the internal bus and neutral bar components needed to terminate branch circuit breakers within a compatible loadcenter enclosure. Combination mounting type allows flexible installation configurations. Licensed electricians install this component during new construction panel builds or when upgrading an existing electrical service to higher circuit capacity.

The i2040l1200cu is suited for residential applications where a high circuit count is required in a single-phase 120/240-volt distribution panel. Its main lug configuration means the incoming service conductors land directly on the lugs rather than a main breaker, making it appropriate for use as a sub-panel fed from an upstream disconnect or main breaker panel. The neutral bar is included, simplifying neutral wire termination during installation.

Key Features

• 200A amperage rating supports full residential service load distribution
• 120/240 VAC single-phase voltage rating for standard North American residential systems
• Main lug design allows use as a sub-panel or downstream distribution interior
• Neutral bar included for direct neutral conductor termination
• Combination mounting type for installation flexibility
• High circuit capacity interior for applications requiring numerous branch circuits

Compatibility

Designed as an OEM-style replacement or upgrade interior for single-phase residential main lug loadcenter enclosures rated at 120/240 VAC and 200A. Confirm enclosure model compatibility before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NFPA 70 (NEC) and all applicable local codes. De-energize and lock out the upstream service or feeder disconnect before handling any interior components. Verify that the enclosure accepts this interior assembly before mounting. Torque all lug connections per the terminal markings and NEC requirements for the conductor size used.
