Is there a standard for this? I'm trying to find information about any codes or standards regarding illuminated indicators on power switching equipment. For example:
A device is designed to automatically switch a load from Supply 1 (230V, 30A, single phase) to an alternative supply. The two supplies are isolated from each other at all times. The device has illuminated lights (with written legends) to indicate things like the presence of either supply, and the supply the load is connected to.
I have seen systems with different colours for power supply and load, and some with the same colour for everything. Is there any standard or industry agreement for this?
