Environment

  • Python version: 3.7.3
  • NetBox version: 2.6.3

Steps to Reproduce

  1. Define a Power Feed 'Feed1' (for example: 380V, 16A, Three-Phase);
  2. Define a new Device Type 'Test PDU' adding a Power Port 'Input1' with maximum draw of 11600W and a number of outlets associated to the three legs (for example: 12 for Leg A, 12 for Leg B, 12 for Leg C);
  3. Create a new device 'PDU1' with 'Device Role 'PDU' using the Device Type template previously created;
  4. Attach the Power Port 'Input1' to the feed 'Feed1';

The 'Power Utilization' box doesn't show the Feed Legs.

Expected Behavior

Same as Netbox 2.6.2, after attaching the feed to the PDU Power Port, the Feed Legs are displayed in the 'Power Utilization' box.

@jeremystretch commented on GitHub (Sep 18, 2019):

This is happening because you've manually defined a maximum aggregate draw for the power port. If you remove that, NetBox will dynamically calculate the draw per leg based on connected outlets.
