In a bathroom application, I recently installed two 300watt halogen vanity lights that are controlled by one single-pole switch. On the same power source (hot wire) are two other lighting sources (and switches)in the bathroom. Prior to installation, all switches operated normally. When I installed the dimmer switch (first a 600w then a 1000w-halogen) for the vanity light, however, ALL THREE switches failed to operate. (Yes, I even switch the wires to cover all options) Strangely enough, when I moved the dimmer swithch to one of the other two switch locations (all are single-pole), the dimmer did work. The switch for the dimmer receives the "hot" wire from the adjacent switch. My efforts tend to indicate that the wiring may be the problem. Can you help me to understand what may be my problem?

Generally there is one hot wire or circuit per switch box that feeds all the devices. The white or neutral wires are usually twisted together. When you installed the dimmer switch you must have disconnected the hot wire to the other switches by mistake. Sounds like you got things corrected, otherwise the breaker would have tripped indicating otherwise. Glad to hear that you used a 1000-watt dimmer on that 600-watt load. Be careful!
