In the C&I sector, new “spec” buildings are often built with 400 amp or 600 amp polyphase bolt in meters. Later, when the building is leased it is sometimes determined that the meter and service panel are significantly oversized for the tenants expected load. The Marwell SP-2387-K7-2-2S adapter may be used to install a conventional residential single phase meter, class 200 or 320, at these sites.

Based on popular Marwell K7 conversion adapter, first introduced in January 2002. We simply modified the adapter by removing the “B” phase circuit and neutral. The remaining bus bars are positioned perfectly for a 2S residential meter. Rated for 320 amps continuous, the adapter may be an ideal solution for downsizing those “spec” buildings to support single phase loads.

The bus bars are 1/2 inch square copper, close coupled to Marwell’s patented Mighty-Jaw . A strong combination for heavy duty applications.
