Electrical docking station
Systems and apparatuses for access-controlled electrical docking stations that automatically switch power to an electrical system between generator power and utility power are disclosed herein. An illustrative electrical docking station can include a cabinet that houses a circuit breaker, a generator interface to connect generators to the electrical docking station, an Automatic Transfer Switch, and a power supply. The power supply can supply converted DC power and protection to different accessories for the electrical docking station including an alarm, a supervisory control and data acquisition (SCADA), and a locking mechanism. The locking mechanism can be configured to lock a door to the generator connectors in a closed position when the ATS is energized by a generator and to not lock the door when the door is in an open position. In some such circumstances, the alarm can shine green or provide an audible alarm and shine red respectively.

5. The electrical docking station of claim 4 , wherein the generator connection compartment includes a bottom surface with one or more cable slots, each cable slot having a width that allows the cable to pass through the cable slot but prevents the connector from passing through the cable slot.
6. The electrical docking station of claim 4 , wherein the generator interface is positioned at an angle that is non-perpendicular with a back side of the cabinet.
7. The electrical docking station of claim 1 , wherein the cabinet includes a riser connected to an interior surface of the cabinet, the riser being adjustable relative to the interior surface of the cabinet to accommodate hardware of various sizes.
8. The electrical docking station of claim 1 , further comprising:
(e) a power supply electrically connected between the generator interface and the electro-mechanical locking mechanism, the power supply being configured to convert high-voltage AC input power from the generator interface to DC output power and to send converted generator power to the electro-mechanical locking mechanism.
9. The electrical docking station of claim 1 , further comprising:
(e) an alarm connected to the cabinet and configured to provide an alert if the building electrical system and the generator interface are electrically connected through the transfer switch and the door to the generator connection compartment is in the open position.
10. The electrical docking station of claim 9 , wherein the alert comprises an audible signal.
11. The electrical docking station of claim 9 , wherein the alert comprises a visual signal.
12. The electrical docking station of claim 9 , wherein the alert comprises an audible signal and a visual signal.
