adjacent to the pool equipment )
• Identified by marking of its location on the switchboard at which the circuits supplying the pool or spa originate , or other permanent location
• Appropriately designed and constructed PLUS protected against mechanical damage and damage due to corrosion .
POOL EQUIPMENT LOCATION The Wiring Rules prescribe two measured zones around the perimeter of a pool . The innermost zone ( Zone 1 ) limits the type of electrical equipment in this specific area . The second outer zone ( Zone 2 ) allows non-essential pool equipment to
meet lesser electrical specifications .
Zones are essential to be established during the planning stage , as electrical overhead power lines , their connection points , switchboards , metering enclosures and solar equipment are prohibited from being located within these zones .
Commercial and medical pools require larger and specialist equipment and therefore involve high-level electrical engineering assessments that require additional earthing methods to achieve the same low-risk design .
AVOID EXPENSIVE COST OVERRUNS 1 . Discuss the electrical work with your electrical contractor . 2 . Plan ahead . 3 . Engage with your electrical contractor early in the design / planning process .
4 . Provide your electrical contractor with site plans and equipment specifications .
5 . If possible , eliminate by alternative design any conductive metal within arm ’ s reach ( 1.25m ) of the pool edge .
Please note , this is general guidance of the intent of the Wiring Rules . State regulators may have variances to this advice . Homeowners are strongly advised to engage with a licensed electrical contractor ( Master Electrician ) to seek the best possible outcome .
