Subject: Multiple electrical power sources
A new question.
A client's product is using two independent AC power sources on a product,
but I can't find anything in 61010-1 60204-1 that provide any guidance on
compliance.
The obvious is that the sections of the product that are fed from source A
or B are not interrelated in any way that would create a hazard for for the
other section, that there be a warning label adjacent to each input that says
there are multiple AC sources, and that each section has it's own circuit
protection and disconnect, even if a facility disconnect is used for both.
What am I missing?
Thanks,
Steve Brody
