Electrical junction box with built-in isolation transformer
An electrical junction box with a built-in isolation transformer is provided. The junction box comprises an interior base portion having at least one opening, a transformer secured to the interior base portion and in electrical communication with low-voltage and high-voltage terminals, a cover configured to attach to a junction box base plate and housing the interior base portion and the transformer, and a gasket providing a watertight seal between the cover and the junction box base plate.
1. An electrical junction box, comprising:
a cover removably attachable to a base plate of an existing junction box installation, the cover defining an interior cavity;
a base portion coupled to the base plate, the base portion dividing the interior cavity of the cover to form a high-voltage section and a low-voltage section within the interior cavity of the cover, the high-voltage section isolated from the low-voltage section;
a transformer positioned within the interior cavity of the cover and mounted to the base portion, the transformer in electrical communication with high-voltage terminals and low-voltage terminals, the high-voltage terminals positioned in the high-voltage section and the low-voltage terminals positioned in the low-voltage section; and
a circuit board including a microprocessor, the circuit board positioned within the interior cavity of the cover and remotely controlling one or more pool, spa, or landscaping lights wired to the circuit board.
2. The electrical junction box of claim 1 , wherein the microprocessor controls the one or more pool, spa, or landscaping lights.
3. The electrical junction box of claim 2 , wherein the microprocessor controls colors and/or intensities of light generated by the one or more pool, spa, or landscaping lights.
4. The electrical junction box of claim 1 , wherein the circuit board includes a power line carrier receiver for receiving commands for remotely controlling the one or more pool, spa, or landscaping lights.
5. The electrical junction box of claim 4 , wherein the commands are transmitted to the power line carrier receiver over one or more power lines connected to the electrical junction box.
6. The electrical junction box of claim 1 , further comprising a wireless receiver in communication with the circuit board, the wireless receiver wirelessly receiving a command for remotely controlling the one or more pool, spa, or landscaping lights.
7. The electrical junction box of claim 6 , further comprising an antenna in communication with the wireless receiver for wirelessly receiving the command.
8. The electrical junction box of claim 1 , further comprising a switch in electrical communication with the circuit board, for remotely controlling operation of the one or more pool, spa, or landscaping lights.
9. The electrical junction box of claim 1 , wherein the circuit board communicates with a remote device external to the electrical junction box.
10. The electrical junction box of claim 9 , wherein the remote device comprises a pool/spa system controller.
11. The electrical junction box of claim 1 , further comprising a gasket positioned between the cover and the baseplate.
12. The electrical junction box of claim 1 , further comprising a second junction box connected to the first junction box in a ganged arrangement.
