Primary/Reserve Power Cabinet Hardware

The lightweight and compact design enables easy wall or floor mounting. The BFIF hardware
kit is needed for floor mounting. If floor mounting three or more cabinets, AC and reserve
power must be connected to the BCCB conduit connection box option by a licensed
electrician. If more than two cabinets require reserve power batteries, the BBDB must be
installed. Wall mounting the system does not require special hardware.
Local electrical codes require certain standards for connecting commercial AC and reserve
power to the Strata CT system.
