I'm working on wiring a layout in my sons room and wondering what fire/safety concerns there might be. I was specifically wondering how safe are some of the electrical connections and components might be. For instance do bridge rectifiers, miller signs converter modules, or exposed leads on leds pose much heat or shorting risks? The layout is about 18 inches off the ceiling and will have no incandescent bulbs, but a few accessories such as crossing gates and miller signs. I have no concept of how safe or unsafe lower voltage ac or dc is, so any insight or cautions would be helpful. Thanks.
