If the circuit is 480V with no neutral, select fixtures that are designed for 480V using two 277V hot legs and the ground. There are auto-sensing ballasts that range from 300V to 600V and accommodate 50hZ and 60hZ to adhere to Canadian, European, and other electrical infrastructures. Here are typical wiring option diagrams for U.S. installations:
Canadian high voltage is 600V that breaks down into two legs of 347V. This requires lighting with Canadian specifications unless using a stepdown transformer. It is best to consult a licensed electrician or an electrical engineer to be sure about purchasing the right fixtures. In-Rush current is also an important consideration. Make sure to check on in-rush current to ensure against overvoltage when turning lights on. Since MIL like Snow-Bright™ does not have in- rush, it is not a concern; however, LEDs that do not incorporate capacitor start-up components will spike current demand. On new installations, it is usually best to keep lighting circuits independent and separate from other applications like snow-making or ski lifts. Lower voltage lighting ranging from 110V to 277V is usually less expensive. Keep in mind that higher voltages use less current (amperage). Fixtures that operate on standard 110V/120V can be used when mounting on buildings because they can be tied into available electricity outlets. Risk Mitigation Nighttime activities have associated risks. Anytime operations are expanded to include activities like night skiing/riding, terrain parks, halfpipes, jumps, moguls, and racing, there is liability. Sports lighting has been associated with accidents, environmental impacts, light pollution, and even eye damage. When faced with such exposure, it is important to consider the most common generalized accusation that those responsible “knew, or should have known” about dangers, risks, exposures, and consequences.
