Junction Box Wiring
All TuffSeal junction box models have been designed to connect and trim up to four
load cells per board.
It is possible to use this box with other combinations. Use the expansion port on the
main board, to connect multiple junction boxes in series to accommodate applications
that have more than four load cells.
