Selectivity: breakers that work together

Selectivity means only the faulty circuit trips, not the whole floor. GorkyCAD checks the chain: input breaker → floor → group → socket — and shows where selectivity fails.

How it works

  • GorkyCAD builds the protection chain from your panel;
  • Compares ratings and tripping curves (B/C/D);
  • Flags zones without selectivity — you fix before installation.

FAQ

Why is selectivity important?
Without it, one faulty socket turns off the whole house or floor. With selectivity — only the damaged circuit.
What curves are supported?
B, C, D trip curves with current and time coordination.
