How is wire identified?
Marked on the component terminal block
On the terminal ring of the wire
Its type identification imprinted along its length
Where should the wire identification and markings be placed?
Identification markings should be placed at each end of the wire and at 15-inch maximum intervals along the length of the wire
Identification markings should be placed at each end of the wire and at 16-inch maximum intervals along the length of the wire
Identification markings should be placed at each end of the wire and at 13-inch maximum intervals along the length of the wire

2/1-inch deflection with normal hand pressure
2/3-inch deflection with normal hand pressure
½-inch deflection with normal hand pressure
Splices must be staggered why? Select all that apply.
minimizes any increase in the size of the bundle
preventing the bundle from fitting into its designated space
causing congestion that adversely affects maintenance
There should be no more than?
Two splices in any one wire segment
Three splices in any one wire segment
One splice in any one wire segment

What is Grounding?
Process of electrically connecting conductive objects to either a conductive structure or some other conductive return path for the purpose of safely completing either a normal or fault circuit.
Process of electrically connecting conductive connectors to either a conductive structure or some other conductive return path for the purpose of safely completing either a normal or fault circuit.
Process of electrically connecting conductive objects to either a conductive structure or some other conductive return path for the purpose of safely completing either a complex or fault circuit.
What is Bonding?
Electrical connecting of three or more unconducting objects not otherwise adequately connected
