Question 1

Walk me through how you lock out and tag out a panel before you work on it.

Accepted Answer

This is the one answer that can get you hired or sent home. Shortcuts on lockout are how people get hurt, and the foreman is picturing you alone in a basement with nobody checking. Identify every source feeding the equipment, including backfeeds from generators or solar Shut it off, apply your own lock and tag, and keep the key on you Test your meter on a known live source, test the circuit, then test the meter again Say plainly that you treat every conductor as live until you've proved it isn't

Question 2

A customer says half the outlets in the kitchen stopped working. How do you track it down?

Accepted Answer

Service calls like this are the bread and butter of a lot of shops. They want to hear a method, not a guess. Ask what happened right before it stopped, like a new appliance or a tripped breaker Check for a tripped GFCI upstream, since kitchen circuits are often protected from one receptacle Find the last working outlet and the first dead one, then open them up and look for a loose backstab or burned connection Confirm the fix under load before you pack up

Question 3

How do you stay current on the NEC and local amendments?

Accepted Answer

The code changes on a regular cycle and your city or county may add its own rules. A failed inspection costs the shop a return trip and makes them look bad to the general contractor. Name the continuing education you take to keep your license active Mention how you check local amendments, like calling the inspector's office or reading the jurisdiction's adoption notes Give one example of a change that altered how you wire something, such as where AFCI or GFCI protection is now required Say you'll ask the inspector before rough-in when you're unsure

Question 4

Tell me about a time an inspection failed on your work. What happened next?

Accepted Answer

Everyone fails one eventually. They're checking whether you own it or blame the inspector. Describe the specific write-up, like missing box fill calculations or an unbonded water line Say what you fixed and how fast you got it back on the schedule Explain what you changed so it didn't happen again Keep the tone calm about the inspector, even if you thought the call was picky

Question 5

How do you size a conductor and overcurrent protection for a new circuit?

Accepted Answer

It's a quick way to see if you understand the reasoning or just memorized a chart on the wall. Start from the load and whether it's continuous Pick the conductor from the ampacity tables, then adjust for ambient temperature, bundling and terminal ratings Check voltage drop on long runs Match the breaker to the conductor and the equipment's nameplate

Question 6

You're on a commercial job and the prints don't match what's built. What do you do?

Accepted Answer

Field conflicts happen on almost every job. They want someone who flags it early instead of improvising and hoping. Stop and document it with photos and notes on the print Tell the foreman before you install anything that locks in the wrong layout Suggest a practical fix if you have one, but let the foreman or engineer decide Know that a change like this may need an RFI, and that's how the shop gets paid for extra work

Question 7

What test equipment do you carry, and when do you use each piece?

Accepted Answer

Your tools say a lot about the work you've really done. A CAT-rated multimeter and a clamp meter as the everyday pair A non-contact tester for a quick check, never as the final word An insulation resistance tester (a megger) for motor and feeder work if you've done commercial or industrial A circuit tracer and a receptacle tester for service calls

Question 8

Tell me about a job where you had to tell a customer something they didn't want to hear.

Accepted Answer

Service electricians sell as much as they wire. The shop needs someone who's honest without scaring people off. Pick a real case, like an old panel that needed replacing or aluminum branch wiring Explain the risk in plain words and show them what you found, with a photo if you can Give options at different price points and let them choose Mention how it ended, including if they said no

Question 9

You're running behind and the GC is pushing you to energize before the work's fully checked. How do you handle it?

Accepted Answer

Schedule pressure is constant. They want to know you'll hold the line on safety without starting a war on site. Say you won't energize until terminations are torqued and tested Give the GC a realistic time instead of a flat no Loop in your foreman so the decision isn't only yours Look for something else you can hand over now to keep other trades moving

Question 10

How do you train or work with an apprentice?

Accepted Answer

Most crews pair a licensed hand with apprentices. How you talk about them shows whether you can run a small crew. Give them real tasks and check the work, instead of only handing them the broom Explain why, not just how, especially on grounding and bonding Keep them away from live work they aren't ready for Share one apprentice who got better because of something you did

Question 11

What's the neatest job you've done, and what would you do differently now?

Accepted Answer

Clean, labeled panels and straight conduit runs are how shops win repeat work. They also want to see you can critique yourself. Describe it with specifics, like a panel change or a run of EMT with clean bends Mention labeling the panel directory properly and leaving the site clean Name one thing you'd improve, such as planning the conduit layout before the first bend Offer photos if you have them on your phone

Question 12

Why do you want to work here instead of where you are now?

Accepted Answer

They're checking whether you'll stick around and whether you did any homework on the shop. Name the kind of work they do that you want more of, like service, new construction or industrial Say what you're looking to learn, such as controls or estimating Keep it positive about your current employer Connect it to where you want to be later, like running your own crew
