Panel indicators, pilot lights, and alike are components necessary for safe and reliable operations of certain machines and equipment. A C44-BCA2-CYO is one such component typically used to spot and diagnose potential fault currents in electrical circuits. This section addresses the working principles and application field of C44-BCA2-CYO.

In brief, C44-BCA2-CYO is a type of fault current indicator (FCI). To comply with the safety guidelines of the Occupational Safety and Health Administration (OSHA) in the U.S.A., building wiring must include a fault current indicator. By doing so, fault currents can be detected and the written warnings on the device will inform the workers of the fault. Fault currents have the potential to cause product damage and disruption to the services.

C44-BCA2-CYO utilizes a differential transformer principle to measure the magnitude of the fault current. When a fault current is present, a bridging current will exist between the neutral and ground wire. The transformer’s role is to detect the flow of the current and produce an instantaneous electrical output at the pick-up relay points. Consequently, this activates the indicator, allowing the user to note the presence of such fault.

The maximum limit of fault current in the circuit should not exceed 20 amperes, which is the limit specified by the National Electrical Code (NEC). When the indicators detect higher than 20 amperes of fault current, then a switch or a switch breaker will be commonly used to protect the line from further damage. However, note that the switch should only be used in cases of absolute emergency and in normal situations all testing should be done by professionally skilled personnel.

C44-BCA2-CYO application field ranges from testing and inspection of residential wiring in single-story detached dwellings and multi-story residential buildings to industrial settings like schools, hospitals, shopping malls, and public buildings. Such indicators are also essential for tests of existing building wiring systems that use low-voltage AC circuits.

In general, C44-BCA2-CYO\'s are used to diagnose the presence of fault currents in the line of an electric network. It is a crucial component in any safety system as the automatic detection of any fault current greatly reduces the potential risk of electric shock and product damage. This widely applicable indicator comes in a wide variety of sizes and shapes to suit the needs of any industrial setting.
