I am putting in a small laundry room in my garage. I have an electrical plug in the room currently active. I ran electricity from it to another outlet then though a wall switch connected to a single bulb ceiling light. The new and old outlets work great, though when I turn on the overhead light the 30 AMP fuse blows. I had nothing plugged into the outlets at this time. Any suggestions as to why the light is blowing the fuse.

Thanks
