True/False
When projecting a ground through a set of disc, the disc shall have the same tag number as the grounds
True
What conditions must be met before projecting grounds

True/False
In the interest of saving time during emergency situations, it may be necessary to limit a Type 1 inspection, even further, to include only that equipment that is directly involved in the emergency, and its solution
True
True/False
On a 230kv Bus, a CLEARANCE is issued , then the ground is closed
True
What equipment/circuit/Work Authority does the LD generate tags for
- 4.8kV feeders (except as noted above)
- 34.5kV circuits into a Substation
- Transmission lines - Inter-utility Tie Lines
- Transformers with more than one area of jurisdiction
- OKs TO Work Hot with a Hold on 34.5kV circuits
- OKs TO Work Hot with a Hold on Transmission circuits
True/False
May go on Local to perform emergency switching w/o contacting the LD to avoid personal injury
True
True/False
Applying portable grounds if possible and unusually hazardous is required after the CLEARACNE is issued and before work begins at circuits 7.5kv and below
True
Who cannot work in a station w/o an ESO
Building Repairers
Carpenters Gardeners
Maintenance Laborers
Painters
Plumbers
Non Power System personnel
True/False
Ear Protection must be worn within 20ft. of Air Blast CBs (noise hazard) indoors
False
True/False
Racking in ground devices must be done by an operator
True
True/False
While washing hot insulators and a fire appears, keep spraying until the fire is out
True
True/False
Equipment that is out on a clearance and is missing parts, status is the same as other equipment out on a clearance
True
True/False
□□□□CLEARANCE IN THE FIELD always gets a slash upon issuance
True
True/False
The boxes of a □□□□CLEARANCE IN THE FIELD stamp are used to record the number of such Clearances in the field that exist simultaneously on the same circuit
True
True/False
Work is to be done at DS-208 under a Primary CLEARANCE, LD will tell RS-I, DS-208 has a CLEARANCE in the Field on the line
True
MAD
4.8kv
5kv

Switch and Leave Policy does not apply to which Work Authority
SWR
Which work condition is allowed under a Switch and Leave
Multiple Crews
Test Relays and Trip CBs
RTU work
Aerial Work
Man Lift
None of the above
Switch and Leave applies to
SSO
ESM
ESC
ECC

True/False
< 600v, employee cannot be assigned to work alone except when clearing trouble, responding to hazard, emergency situation, or when performing work not contacting energized conductors
True
True/False
Prior approval of superintendent of crew required to project grounds
False
Who does not need an ESO
QEW
Authorized Person
A Person that is authorized to receive Work Authorities on circuits and equipment from the Load Dispatcher or their Field Representatives
Authorized Person
True/False
138/230Kv Bus ground switch can be opened for work without asking LD and substituted with portable grounds
True
True/False
Line Patrol Mechanics can work on Pot Heads if already grounded and tagged without an operator present
False
True/False
Issuing of an OK TO work hot on a circuit should not prevent issuing of a CLEARANCE except if OK TO conflicts/violates the CLEARANCE
True
What is discussed regarding limits and hazards
Opens, electrical/physical hazards, nature of work performed, equipment/tools needed
Who can work under Work Authorities and re-issued OKs TO
Authorized Person
True/False
Cannot connect CBs to source load test under a CLEARANCE, only under an OK To
True
If a worker bids a Clearance on this type of CB and the bid does not specify that air be left in the receiver, what must the operator do
-The air tank supply valve must be closed and left closed.
-The DC control switch and low pressure alarm switch must be opened and left open.
-The air tank must be completely drained of air by opening and leaving open it’s drain valve.
-The air tank supply and drain valves must be properly tagged to prevent further valve operation
What are some of the risk/dangers of paralleling regulators one step of neutral.
Excessive and dangerous circulating current will result which may cause equipment damage, personnel injury, or relay operation
