(iv) within self-contained equipment supplied at low voltage;

(f) electricity generation systems including any wiring systems, switchgear, controlgear or accessories installed to provide control or protection to those generation systems (excluding stand-alone power systems with a power rating that is less than 500 volt-amperes);

(g) electric fences used for security purposes but not including electric fences intended primarily for the containment of animals;

(h) electrical equipment installed in a hazardous area and electrical equipment associated with the protection of a hazardous area but not installed within the hazardous area;
