General question about the standard or regulations involving how a pull cord e-stop circuit is wired.
Can a pull cord circuit be wired through a PLC for a stop command to be implemented, or does it have to be hard wired back to the contactor of the starter for the conveyor motor?
Are both...
I have a fuse that apparently has two ratings. On the datasheet for the fuse on the SIBA site, it has a rated current of 140A. It was sold to my group as a 250A fuse.
SIBA 3019614.250
The In = 250RC140A
My understanding is that this is a 140A rated fuse with the 250A referring to the designation...
Because I'm not an engineer, and I'm currently in heated discussions with an electrical engineer, I need some theoretical assistance with the following circuit.
13.8kV primary to 600V secondary, 600V secondary to 600V/4.16kV autotransformer to 4.16kV softstarter, softstarter to 4.16kV motor...
Good day all,
With the available settings in ETAP in reference to the SEL-751A, how do I incorporate the fiber-optic arc-flash detector to lower the category of the busses that I am faulting. The only curves I can alter are the normal phase, neutral, ground, and negative sequence overcurrent...
