Cl 2.5.5, Cl 2.10.2.2 and App K Table K2

Switchboard internal separation, access and clearances

The file follows AS/NZS 3000:2018 with Amendments 1, 2 and 3. Its Cl 2.5.5 and Cl 2.10.2.2 figures are normative. The one exception is the 2.2 m doorway height, which a NOTE gives as advice. Everything from Appendix K is informative, and the tool prints it as an example. The switchboard form tool reads one rule row and one row per rated impulse withstand voltage. The rule row holds the 800 A separation trigger and the accepted forms and suffixes. It holds the face and surrounding clearances and the domestic figure. It holds the two-exit triggers, the clear-space exception and the 2.0 m by 0.9 m clear doorway. It holds the creepage distance and the three conditions that figure needs. Each impulse row holds the clearance, the alternative test voltage and the overvoltage category for its Uimp.
