Distribution Design

Power distribution from service to branch

Model your power distribution system from the utility service entrance through switchgear, distribution panels, and branch circuits. Every level has fault current, voltage, and sizing calculated automatically.

What you get

Full system modeling

Model from utility source through transformers, switchgear, distribution panels, and branch circuits.

Fault current at every level

Available fault current calculated at utility, switchgear, distribution, and branch circuit levels.

Voltage from source to load

Bus voltages and voltage drop tracked from the service entrance to the farthest load.

Equipment sizing throughout

Cables, breakers, and equipment sized per NEC at every level of the distribution system.

AIC verification

Equipment interrupting ratings checked against available fault current at every point.

System-wide view

The complete distribution system in one model

Power distribution design requires understanding the system holistically — fault currents propagate down, voltage drops accumulate, and equipment at every level must be properly rated.

  • Model the complete distribution hierarchy in one diagram
  • Fault current propagation visible from source to branch
  • Voltage drop accumulates and is visible at every level
  • Equipment at every level sized and verified automatically

Frequently asked questions

How many levels of distribution can I model?

As many as your system requires. Utility → transformer → main switchgear → distribution → panels → branch circuits. No artificial limits on hierarchy depth.

Can I see fault current propagation?

Yes. Fault current is calculated at every bus, so you can see how it decreases as you move further from the source through transformer and cable impedances.

Does it track cumulative voltage drop?

Yes. Voltage drop accumulates through each cable and transformer in the path. You can see the total drop from source to any load.

Is this suitable for medium voltage systems?

Yes. ekx models systems at any voltage level, from utility medium voltage through low voltage branch circuits.
