A question on registered electrical engineers
Thread Content
Dear marine friends, I have a question related to registration issues: For the control circuits of remote-controlled and unattended substations, which approach is appropriate? A. Wiring with automatically resetting control switches； B. Wiring with the control switch in a fixed position ； C. Wiring of the open/close button ； D. Wiring of the on/off button with lighting. Please help analyze it, thank you
Based on logical reasoning, it should be A; it is required to have an automatic reset function that can operate without human intervention.
