Square-D QO112L200GRB 200 Bus Amp Single-Phase
Square-D brand load centers can be used for multiple purposes, for wiring that meets the national electric code (NEC). All of these can be used as AC load centers or sub-panels. Panels using QO plug in breakers are rated up to 50 VDC for use as 12V or 24V DC Load Centers. It can also be used to combine the AC output for multiple inverters feeding the grid. When used as DC load centers they should be protected by a high interrupt capacity, fuse or circuit breaker between the load center and the battery. Use one of the Class T or Class R fuses, or the DC breakers used in the outback and xantrex DC power centers.
When used to combine the AC output of multiple grid-tie inverters, and meet the requirements of NEC 690.64 (B)(2) the bus amp rating for the load center must be larger than the sum of all of the over-current devices feeding it, from both the utility and all inverters.
The 277/480V load centers can be used to combine the output from multiple inverters to feed a 277Y/480VAC grid interconnection. One 30A continuous duty breaker is used for each inverter that is set up for 277V hot to neutral.
Load centers are not supplied with any breakers - order condiut hubs for outdoor load centers.
