JHBB switchboard frame has been designed to provide a solid platform on which to build customised switchboard products. Individual switchboard sections are built from formed steel channels and angles, then secured together with thread-rolling screws. These thread-rolling screws, when compared with regular self-tapping screws, provide superior torque and strip-out resistant qualities.
Section dimensions are determined by the type, size, quantity, and arrangement of the components and devices being installed.
All covers, doors, and frames are made of formed steel for extra rigidity. A deep front corner channel and side plate covers the sides. The back is covered with removable plates that have formed edges. All covers are secured with slot/hex head thread rolling screws which greatly minimize the chances of thread strip-out.
The standard paint finish on all JHBB switchboards is an over an iron phosphate pretreatment. Non-standard finishes are an available option when specified.
JHBB switchboards are available in either indoor or outdoor enclosures.
JHBB section 2000 A or less has removable lifting bars and is clearly labeled with handling procedures. The sections are shipped separately to allow the installer extra flexibility when moving the sections to the desired location. Once in place, the sections are secured together, linking the strength of each frame. Optional multiple-section shipments do not have
lifting bars.
