Question 1

Does this include power factor or reactance?

Accepted Answer

This educational estimator typically models resistive drop only. AC circuits may require more advanced calculations.

Question 2

Why do codes specify percent drop limits?

Accepted Answer

Because excessive voltage drop can cause poor performance, overheating, and noncompliance with equipment requirements.

Question 3

Is this safe for wiring decisions?

Accepted Answer

Use this for learning and early checks. For actual electrical work, consult a qualified electrician and follow local codes.
