I am reviewing the use of an "In-Roadway lighting" system which is typically used at crosswalks. Many of these systems operate at 12 VDC, 3 amps, with LED lamps, operating from wires placed in a sawcut in the road surface. These systems are fairly safe, being similar to low voltage landscape lighting.
One system operates at 38.4 kHz, about 30 volts, perhaps 4 amps. The LED lamps are inductively powered from the cable.
I'm trying to determine what the shock hazard at 38.4 kHz would be. any comments or suggestions on where to look?
