I just have some questions I cant seem to find or understand because I am teaching myself the electrical code book
what is a target table? how a switch operates?
what does the distance from the centre point depend on, what does that mean?
what does the cec do? is this an organization council?
what is another name for low voltage protection? 3 wire control? why?
what is eol and how does it operate? is that end of line for fire systems? is it a supervisory current meaning it keeps the fire alarm current in line?
I know an overload is when the current is above the wires ampage? and is it connected in the power service and control service?
I know the electrical definition of a service factor but I don't really understand it, could it be explained?
how do I calculate this question? a service factor of 1;15 what is the maximum current for the overload setting? what tables do I use?
I cant answers all of this question?
wex 100 hp motor, 575 volt, and sf of 1:15
a) fla of the motor table 44 -99 amps
b)maximum overload current? how do I do this?
c)what is the wire size using type r90?
what size time delay fuse would we use?
what is a jog circuit, I know that when you use the start button the path is completely ocmplelt by what diffenrece does the jog button have?
I have no one to teach me so please help would be great in good detail and explanation
