Any leakage of _____ from electrical equipment is run to ground directly through the grounding system, rather than through other equipment, or through a person that touches the equipment.
1) Current
2) Protons
3) Voltage
4) Resistance
5) Magnetic flux
Current
In an electrical system, the neutral wire:
1. Is connected from the generator to the load
2. Has no over current or fuse in its circuit
3. Is connected to earth at one or more points
4. Carries no current when the electrical load is balanced on each side
5. Carries twice the current when the electrical load is balanced on each side
1) 4
2) 1, 2, 3, 4
3) 1, 2, 3, 5
4) 1, 2, 4
5) 5
The utility's responsibility will not go beyond the:
1) Motor control center
2) First over current device
3) First trunk circuit
4) First branch line
5) Primary transformer
First over current device
Before working on any electrical equipment:
1) Connect a grounding strap
2) Tell someone
3) Make sure the supply is energized
4) Be sure the supply is disconnected
5) Have the switches closed
Connect a grounding strap
A prime factor in determining the voltage to be used in a circuit is:
1) Transformer capacity
2) The resistance of the circuit
3) Degree of access to equipment
4) The number of motors involved
5) Peak demands
Degree of access to equipment
