Issues and safety precautions to take with a 50-70 feet 12v bus line? Answered
i am thinking of building a emergency LED setup with some 1w or 3w LEDs which will be connected to a 12v bus line powered from a deep cycle battery. I will be using a fuse between the battery and the bus line. I am thinking of placing a cluster of LEDs every few feet(7-10 feet). Each LED will be powerd using a mr16 LED driver using power from the bus line and the driver should consume somewhere around 350ma of current. Each LED will be mounted on a heatsink. Max LEDs in a LED cluster will be 3 no.s . Total current used when all the LEDs are on should be around 6 amps max.
So, the question is, what kind of safety issues should i look out for and what type of wire i should use for bus line and the lines to leds. Also, should i be using relays for LEDs or will switches be fine? And what precautions should i take ?
