I know that when sizing cable for a particular motor circuit it needs to be 125% of the FLA of the motor.
My question is what happens when you are tapping off of a bus to feed the line side of a breaker in a combination motor starter? Does this tap also only need to be 125% of the motor FLA or should the tap be sized per some other breaker (upsteram?) rating? What section of the code references this?
My second question is can an instantaneous motor breaker be used to feed multiple motor overloads to in turn feed several motors?
Lastly, I seen before where feeders have hit the line side of a breaker and then were jumpered to the line side of another breaker and so on to basically supply incoming power to the line side of several breakers. How many times can these jumpers be jumped to connect various breakers? Is this basically like a bus or is it considered to be a varation of the tap rule? I'm guessing it is considered a bus and needs to adhere to the rules for sizing bus.
