Important notes
  • Confirm the manufacturer cable resistance, loop convention, operating temperature, connectors, and feed arrangement.
  • Licensed electrical review remains required for Australian low-voltage installation decisions.

Formulas

  • \(\displaystyle V_{\mathrm{drop}} = I \times L_{\mathrm{one-way}} \times R_{\mathrm{per\,m}} \times N\)
  • \(\displaystyle V_{\mathrm{end}} = 24 - V_{\mathrm{drop}}\)
  • The result is a preliminary cable planning check, not a certificate or installation approval.
