Data circuit

[hhsting]

I have radiation room where their is xray. There are 120V 20A breaker circuits and engineer says these r data circuits.

Would anyone know can their be data circuits 120V fed from 20A breaker?

One guess is that they are for equipment racks or enclosures that hold electronics used for processing/storing/analyzing/exporting data that comes from the actual x-ray machine. So cutting power to them will not directly power down the radiation source.
These days a wide variety of imaging devices have only a digital output from a sensor array rather than producing an image on film.

Yeah that could be possible. I've had low voltage door access controls that were powered via cord plug stepdown transformer (similar to a phone or laptop).
What about low-voltage wired/wireless lighting controls. Typically there is some sort of device or POE injector that is fed from 120V and provides low-voltage output for devices.
What about pump controllers. Ive had 120V 20A circuits fed out to septic pump control panels. Control panel internal circuiting then powers 120V equipment and low voltage alarm floats.
