What are the amperage capabilities of each Box at each voltage?

 

The amperage capacity of the ResiBox is 120A and for the CommBox it is 230 Amps.

The ResiBox has (4) of the 30A/2-pole contactors rated 120-277V for a total of maximum 120A load capacity. The CommBox is limited to 230 amps load when powered at single or 2-phase power. It is built with (4) of the 50A/3-pole relays and an extra 30A/2-pole relay. The latter is only used for additional roof & gutter system or later add-ons.

At 3-phase power, the CommBox presents its full capacity of 600 Amps. Each 50A/3-pole relay can be loaded with up to 150 Amps of the load. This is only true when powered at 3-phase voltage. Please refer to the wiring diagrams and manual to configure your installation.
