um. u have to switch the power off in your room via the fuse boxs or circut breakers(just to be safe{even thu i dont do it when im dealing with electural stuf} due to the fact that my dad has tought me a lot of stuff of about that kind of stuff the only time i cut the power off is when im doing shit to the dryer plug, oven plug, water heater, and the fan in our attict, all using the higher voltage of power) just for learning shut off the power, the circuit breakers on my house our in the laundry room. then get the plastic covers for electrisity, they have different gauge wires so ask the guy at the hardware store for covers for standered home wireing, or buy the black tape, it should have UL on the in side of the roll(witch stands for united labators i belive, all they deal with a UL from what ive seen is electrisity) and wrap all of the wires in seperate sheats of tape or in there own wire covers. its preaty mutch that easy.
