Top 10 Questions for House Wirer Helper Interview

1. Describe the process of installing a new electrical outlet.

When installing a new electrical outlet, I would first turn off the power at the circuit breaker panel. Then, I would use a voltage tester to make sure that the power is off. Next, I would remove the faceplate and screws holding the outlet in place. I would then carefully pull the outlet out of the electrical box and disconnect the wires. I would then connect the wires to the new outlet and push the outlet back into the electrical box. Finally, I would screw the outlet into place and replace the faceplate.

2. What are the different types of electrical wire?

• Solid wire: This type of wire is made of one solid piece of metal, usually copper or aluminum.

• Insulated wire: This type of wire has a non-conductive material, such as plastic or rubber, around the metal conductor.
• Bare wire: This type of wire does not have a non-conductive material around the metal conductor.

3. How do you calculate the amperage of a circuit?

To calculate the amperage of a circuit, you need to know the voltage of the circuit and the resistance of the circuit. The amperage is equal to the voltage divided by the resistance. For example, if a circuit has a voltage of 120 volts and a resistance of 10 ohms, the amperage would be 12 amps.

4. What are the different types of electrical fixtures?

• National Electrical Code (NEC): This code is used in the United States and sets the minimum requirements for electrical installations.
• International Electrical Code (IEC): This code is used in most other countries and sets the minimum requirements for electrical installations.
• State and local codes: These codes may have additional requirements that must be followed in addition to the NEC or IEC.

9. What are the different types of electrical inspections?

• Rough-in inspection: This inspection is done before the walls are closed in to make sure that the electrical wiring is installed correctly.
• Final inspection: This inspection is done after the electrical work is complete to make sure that the electrical system is safe and working properly.
