Project Design & Management — NASCLA Electrical Practice Questions

12 questions · 8% of the NASCLA Electrical exam

Worked questions

1. Approved switchgear has a lead time longer than the current installation milestone. What is the best first project-control response?

AHide the lead time until the milestone is missed
BOrder unapproved equipment with no submittal
CRemove testing activities to recover every lost day
Document constraints and update project logic

Why D is correct

A long-lead constraint belongs in the risk, procurement, and schedule processes. The manager should surface it, evaluate compliant mitigation, obtain approvals, and update dependencies; concealment or unauthorized substitution creates larger technical and contractual failures.

2. The owner verbally requests additional receptacles after rough-in begins. What protects the project most effectively?

ARefuse to record the request
BCharge the field crew personally
Get written change authorization
DPerform the work and hope it is paid

Why C is correct

A verbal request should enter the project change-control process. Scope, price, schedule, and authority must be documented under the contract so the owner understands the impact and the contractor preserves entitlement; undocumented work is a classic dispute source.

3. A repeated torque-inspection failure appears across several installed panels. What is the best management response?

AIncrease every torque value above the manufacturer instruction
Contain, correct, and verify the root cause
CCorrect only the one panel the inspector opened
DCover the remaining panels before inspection

Why B is correct

A repeated defect indicates a process problem rather than one isolated punch item. Containment, root-cause analysis, retraining or tool correction, reinspection, and documented verification reduce recurrence while preserving listed installation requirements.

4. A late switchgear delivery affects an activity on the project critical path. What should the manager do first?

ADelete required testing
BInstall unapproved equipment
Quantify and mitigate impact
DHide the delay until installation

Why C is correct

A critical-path delay can move project completion. The manager should update schedule logic, evaluate compliant alternatives, communicate impacts, and obtain approvals instead of concealing the constraint.

5. A drawing dimension conflicts with the specification. What is the defensible response?

Request clarification before affected work
BChoose the cheaper interpretation silently
CBuild both versions without authorization
DErase the specification requirement

Why A is correct

A written RFI identifies the conflict, preserves design responsibility, and lets cost or time consequences enter change control. Silent interpretation can produce nonconforming work.

6. Which package best supports electrical project closeout?

AOnly the final invoice
BUnmarked bid drawings only
CA verbal statement that systems operate
Tests and closeout records

Why D is correct

Closeout must demonstrate acceptance and provide the owner with usable operating and maintenance information. Billing alone does not document testing, configuration, or warranty obligations.

7. A design calculation predicts 9 volts of drop on a 240-volt circuit. What percentage drop is that?

A2.50%
B3.25%
3.75%
D4.50%

Why C is correct

Divide drop by source voltage and multiply by 100: 9 V ÷ 240 V × 100 = 3.75%. This percentage can then be compared with the project's design criterion.

8. A reviewed estimate subtotal is $18,500 and management applies a 6% contingency once. What adjusted subtotal results?

A$18,610
B$19,060
C$20,350
$19,610

Why D is correct

The contingency is $18,500 × 0.06 = $1,110. Add it once: $18,500 + $1,110 = $19,610. Contingency should remain visible rather than being confused with overhead or profit.

Answers and explanations for these are in the app.

The bid reconciliation shown identifies firestopping in the specification but not the estimate. What should the project manager do before contract execution?
Field installation begins before a required equipment submittal is approved. What is the main risk?
A four-person electrical crew is scheduled for three 8-hour days. How many labor-hours belong in the estimate?
An estimate carries 250 feet of conductor at $3.20 per foot. What material extension results before waste and tax?
