Notes:
- Minimum separation of conductive enclosures to low voltage earthing electrode 500mm for water, sanitary drainage and gas and 600mm for stormwater drainage.
- Low voltage is voltage that exceeds extra-low voltage (not exceeding 50 V ac. or 120 V ripple-free dc.) but not exceeding 1000V ac. or 150 V dc.
