The cross phase jumper symbology is misleading and uninformative.
With phase-to-phase symbology, you can easily tell what phases are present, and what phases are closed.
With cross phase jumper symbology, you have no easy way to tell which phase was connected to which, and when you close the jumper, it looks like all phases have been closed, when in fact only one has been.
The cross phase jumper should show the phasing in a clear manor
The issue can be reproduced at will with the following steps:
1. Place a point-to-point jumper between two three phase conductors.
2. Observe the jumper's appearance.
3. Place an A->C cross-phase jumper between two 3-phase conductors.
4. Observe that the symbol does not clearly indicate what phases are involved.
