HANDS-ON TEST:
COURSE DESCRIPTION:
ElectriCities Apprenticeship Program hands-on test is used to evaluate proficiency for this school. There are three job site scenarios for Transformer School hands-on test: Wye/Wye Bank (120/208), Wye/Open Delta Bank (120/240), and Wye/ Delta Bank (120/240).
Jobsite Scenario - Wye/Wye Bank (120/208)
- Student will make the proper connections required to build a Wye/ Wye (3 pot) bank
- Student will make the proper meter base connections for the Wye/ Wye bank and complete the required voltage test.
- Student will identify each required test point and what the correct voltage should be at each point (i.e., phase-to-ground and phase-to-phase test points)
- Student shall complete the required steps in compliance with the rules listed in the current APPA Safety manual, OSHA standards, and industry standards.
- A score of 80 must be obtained for a passing grade.
Jobsite Scenario - Wye/Open Delta Bank (120/240)
- Student will make the proper connections required to build a Wye/Open Delta (2 pot) bank
- Student will make the proper meter base connections for the Wye/Open Delta bank and complete the required voltage test.
- Student will identify each required test point and what the correct voltage should be at each point (i.e., phase-to-ground and phase-to-phase test points)
- Student shall complete the required steps in compliance with the rules listed in the current APPA Safety manual, OSHA standards, and industry standards.
- A score of 80 must be obtained for a passing grade.
Jobsite Scenario - Wye/ Delta Bank (120/240)
- Student will make the proper connections required to build a Wye/ Delta (3 pot) bank
- Student will make the proper meter base connections for the Wye/ Delta bank and complete the required voltage test.
- Student will identify each required test point and what the correct voltage should be at each point (i.e., phase-to-ground and phase-to-phase test points)
- Student shall complete the required steps in compliance with the rules listed in the current APPA Safety manual, OSHA standards, and industry standards.
- A score of 80 must be obtained for a passing grade.
INSTRUCTIONS:
1. Student must understand the following before proceeding with testing:
- Test Expectations
- Skill Expectations
- Scoring
- Passing Score
- APPA Safety Manual, OSHA Standard, NESC and Industry Standards (to complete this test)
2. Any questions?
3. During Testing...
- A Proctor will observe student’s performance for each of the Skill Expectations and circle each accrued deduction point.
(Note: Proctor will document any other Infractions under the section labeled Other and explain the observed infraction(s) on page 4) - Total Deduction Points: Proctor will add the Deduction Points column and write the amount in the space labeled Total Accrued Deductions Points.
- Final Test Points: Proctor will subtract the Total Deductions Points from the Beginning Points (100) and write that amount in the space labeled Final Test Points and circle Pass or Retake based on Final Test Points (a score of 80+ = Pass and a score below 80 = Retake)
4. Provide Feedback
- Proctor will share results with student at the completion of the test, including any additional Development Recommendations.
5. Result Document Signatures: Proctor and Student must Print, Sign, and Date page 4.
- Student will receive a copy of the final document via email.
6. Return for Files: The original document will be filed with the ElectriCities Learning & Development Specialist.
7. Failed Student: Proctor will contact the student’s Supervisor, if they fail the test, and discuss development Recommendations.
Only the student being tested, and the proctor (ElectriCities Safety & Training staff member) is allowed in the test area. Only ElectriCities’ Safety & Training staff can proctor end of level hands-on testing and graduation exams.
STUDENT REQUIREMENTS - Students are required to bring hand tools and required PPE (hard hat, work gloves, rubber gloves and protectors, ANSI Z87 safety glasses, work boots). Students must either be registered for the particular school or have previously taken the school.
TIMES:
- Thursday: 8:00 a.m.– 5:00 p.m.
CANCELLATION POLICY: If a course is cancelled by ElectriCities, all registrants will be notified with a full registration fee refund. A non-refundable registration fee will be charged for cancellations after the deadline of September 14, 2026.
