Preview Questions Electrician | Role Specific Skill

Question 1: What is the NEC requirement for wiring when installing electrical outlets in bathrooms?

Which action should you take?

Choose only one option

They must be weather-resistant

They must be 20-amp circuits

They must be GFCI-protected

They must be duplex outlets

Question 2: How do wire gauges impact the current carrying capacity of wiring in a circuit design for electrical systems?

Which action should you take?

Choose only one option

Thicker wires (lower gauge numbers) are less efficient but safer

Smaller gauge wires allow for more current flow

Wire gauge has no impact on current flow

Thicker wires (lower gauge numbers) carry higher currents safely without overheating

Question 3: How should an Electrician handle the installation of temporary power systems for construction sites?

Which action should you take?

Choose only one option

Install temporary power systems with proper load balancing, circuit protection, and grounding, following safety regulations for site operations

Use random power sources without proper protection

Use permanent electrical systems for temporary power

Focus only on convenience and ignore safety standards

Question 4: What is the minimum height for an electrical panel from the floor as required by the NEC?

Which action should you take?

Choose only one option

4 feet

5 feet

6 feet

3 feet

Question 5: What is the maximum allowable voltage drop for a 120V circuit according to the National Electrical Code (NEC)?

Which action should you take?

Choose only one option

5%

10%

3%

2%

Question 6: What should an Electrician consider when designing a circuit for a critical load, such as medical equipment?

Which action should you take?

Choose only one option

Ensure the circuit is dedicated to the critical load, uses the correct wire size, and includes redundancy like backup power or UPS systems for reliability

Use a shared circuit to reduce costs

Use the same circuit as other non-critical loads

Ignore load requirements and use the same breaker size as for other circuits
