glad that worked out 4 ya miriam! It also doubles as the dimmer to my incandescent lamp when not used otherwise. It would be beneficial, though i haven't tried it yet is to use a GFCI outlet even tho it's ungrounded. The Gfci will trip pretty quick for an imbalance like a short. Please DO NOT take anything Im saying here as gospil. AC can kill, and a qualified electrician can advise you. Also do research online. At the very least a 1.5 A fast blow fuse would be good
