Abstract
Embodiments of this present disclosure may include a handle disposed on an outer surface of a housing of electrical circuitry. The handle may provide access to at least a portion of the electrical circuitry. The handle may include a status indicator that emits light in response to a control signal from control circuitry. The status indicator may be disposed around the handle. The control circuitry may detect a state of the electrical protection circuitry. The control circuitry may also transmit the control signal to the status indicator based on the state. The control signal may control one or more properties of the light emitted by the status indicator, and thus indicate to an operator the state of the electrical circuitry.
