ABSTRACT:
A breaker apparatus for preventing a power line carrier frequency from moving along a power supply lead. The breaker comprises a core member with a first leg, a second leg and a third leg where each leg extends between a top section and a bottom section of the core member. The top section and a first leg portion define a top core section and the bottom and a second leg portion define a bottom core section. The top and bottom core sections are separate sections. A first power supply line enters the core member from one of the sides of the core member and coils around the first leg of the core member and exits from the same side as entering the core member to form a first coil winding. A second power supply line enters the core member from the other remaining of the sides of the core member and winds around the third leg of the core member and exits from the same side as entering the core member to form a second coil winding. The first and the second power supply lines are connected to a power line carrier frequency generator of a home automation appliance. The breaker enables a power line carrier frequency entering the first coil and the second coil from the power supply to be blocked and a power line carrier frequency inputted by the home automation appliance to be blocked.
