What it represents
An additional fused-switch pole represents another conductor of a common multipole device. Each fuse-link and pole needs its terminal and phase identification while the common operating mechanism stays linked.
How to read it
- A shared device tag should not conceal different fuse ratings on separate conductors.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- Link parent switch tag
- Identify pole and fuse terminals
- Verify common operation
A distinction that matters
A child pole is a CAD representation of a common device, not an extra independently operated fused switch.
