Let’s discuss the installation of conduit and cable boxes for instrument cables!
Thread Content
Regarding the installation of instrument cable conduit boxes, there are differences between the GB and SH specifications. So under what circumstances are elbow junction boxes generally used, and at how many straight sections are straight-through junction boxes used? ? ?
Is there no relevant information in the specifications?
No relevant regulations were found. Could the original poster post the differences for us to take a look? Generally, wire boxes are used for the convenience of wiring or when there are bends.
