In regards to Low Voltage Landscape Lighting applications: I was told by the Department of Consumer Affairs that in the state of NJ, is mandatory that anything over 10Volts be installed by a licensed electrician. They have to direct bury all the wiring and you must apply for a permit. So if you own a Low Voltage Landscape Lighting business you must either be a licensed electrician or contract one per job. This varies per state, but it just came to my attention at a lighting seminar even though this had been in effect since 1998! Anybody else hear about this? when I called certain townships even the electrical official had no idea what i was talking about.
