Install Conduit, Cabling, and J-Boxes 15
8.0 Install Conduit, Cabling, and J-Boxes
Load cells are supplied with 60' cables. Since each cell is temperature-compensated for the supplied cable length,
do not change any cable length. There will be room to coil excess cable inside the junction box after making final
connections.
All cabling must be enclosed in 3/4" weatherproof conduit from the load cell to the junction box in accordance with
applicable electrical codes. NEMA 4 junction boxes are supplied from the factory with 30" sections of flexible
conduit and waterproof conduit adapters where necessary to maintain NEMA 4 integrity.
