Recently, we found that there are many friends calling for consultation or looking for non-standard distribution box (stainless steel distribution box) size problems on the Internet. Here are some references for you:

1. The distance between components shall be convenient for cable connection, component operation, component maintenance and replacement, component flashover distance, etc.
2. The position of how many cables need to be reserved shall be determined according to the cable model and specification, especially the incoming and outgoing ends. If the cable is large and the space is small, it may not bend the cable.
3. Also consider whether there is enough space between the panel mounting elements and the elements in the box, and whether the installation position of the panel elements can open the door, etc.
