Rules for AC power cable to Obs?
Does anyone know what the regulations are (in NSW) for underground AC power runs to an observatory? I want to extend my shed power to the Obs, only about ten metres in total. I only need a single 10amp circuit. This is private AC off my inverter/battery bank which is solar charged - so not grid connected. What is ok? Is 300mm deep enough and do I need special conduit and a coverboard, or tape above it? Thanks
