Product Information
Leviton Load Center Phase Maps
The Leviton Load Center Phase Maps are illustrations designed to simplify the installation process of the Leviton Whole Home Energy Monitor (LWHEM). These maps help identify where the power wires of the device should be terminated based on the location of the 2-pole device used to supply power. Additionally, the maps provide guidance on where to mount the Smart Mains Metering Accessory CTs (LSMMA) for monitoring whole-home energy consumption. The circuit breaker positions labeled in the illustrations are color-coded to match the correct power wire from the Whole Home Energy Monitor for that specific breaker position.
