Care should be taken when deciding the program used in any present wiring. ^ Use of sunshine blue for Neutral may well trigger confusion with dim blue for L3. In New Zealand domestic installations, the sole permitted color for Neutral is black. ^ Australian and NZ cable identification colors and European cable identification colors really should not be mixed throughout the similar wiring enclosure. ^ For protection factors, yellow really should not be utilized when environmentally friendly/yellow striped cables are present. ^ a b Canadian and American wiring practices are incredibly equivalent, with ongoing harmonisation initiatives.

This will compensate for the upper resistance and decrease mechanical energy of aluminium, indicating the larger sized cross sectional place is necessary to obtain equivalent present-day potential as well as other functions. Aluminium conductors has to be set up with compatible connectors and Unique care must be taken to make sure the Call area won't oxidise. Raceways and cable runs[edit]
