Led meter board for a transfer switch

A method for indicating a power level of a power source, the method comprising:

• measuring a first current power value provided by a power source in electrical communication to a load center through a power transfer switch;
• calculating a first provided percentage value of the known maximum available power of the power source to the load center, the first provided percentage value of the known maximum power comprising the first current power value provided by the power source to the load center divided by the known maximum available power level of the power source;
• and
• transmitting at least one control signal to a display associated with the power transfer switch, the power meter comprising a plurality of light emitting diodes (LED), with each one of the plurality of LEDs corresponding to a particular range of percentage values of the known maximum available power from the power source;
• wherein a first one of the plurality of LEDs blinks at a first blinking rate, the first blinking rate corresponding to the calculated first provided percentage value of the known maximum available power of the power source to the load center.

A power transfer switch comprising:

• a switch comprising a first position that provides power from a first power source to a load center in electrical communication with the power transfer switch and a second position that provides power from a second power source to the load center;
• a display comprising a plurality of light emitting diodes (LED) for displaying an indication of a power level provided by the power transfer switch to the load center;
• and
• a control circuit comprising a processor and at least one memory device, the processor executing one or more instructions stored in the at least one memory device, the instructions causing the control circuit to:
• obtain a maximum available power level of the second power source in the at least one memory device, the maximum available power level of the second power source associated with an overload condition of the second power source;
• calculate a first provided percentage value of the maximum power of the power source to the load center, the first provided percentage value of the maximum power comprising a first current power value provided by the power source to the load center divided by the maximum available power level of the power source;
• wherein each one of the plurality of LEDs of the power meter corresponds to a particular range of percentage values of the maximum available power from the power source and a first one of the plurality of LEDs blinks at a first blinking rate, the first blinking rate corresponding to the calculated first provided percentage value of the maximum available power of the power source to the load center.
