Thanks for your responses. Sent from my T-Mobile 5G Device -------- Original message --------From: Steve Brody <[email protected]> Date: 4/6/23 4:41 PM (GMT-05:00) To: PSES List Server <[email protected]> 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 [email protected] C - 603 617 9116
