Electrical work is largely invisible — wires go into walls and ceilings, connections happen inside boxes, and by the time everything is closed up, you can’t see what was done or how it was done. That makes the questions you ask during the job more important, not less. A few targeted questions at key moments keep you informed, catch deviations from the agreed scope, and confirm that the work is being done safely and correctly.
“A homeowner who asks to look at the wire gauge before it goes into the wall, or asks to see the breaker label before the panel is closed, is doing exactly the right thing. I never mind those questions — and any electrician who does mind should make you nervous. You have a right to understand what’s being installed in your home.”

Before Work Starts
Can you walk me through the work plan for today?
A brief pre-job conversation tells you what will be done, where the electrician needs access, and what to expect in terms of power interruptions. For significant jobs, ask which circuits will be de-energized and for how long.
When will the power be off, and to which circuits?
Electricians often need to de-energize circuits to work safely. Ask upfront: which circuits, for how long, and whether the full panel will need to be shut down at any point. This helps you plan — refrigerators, security systems, and work-from-home setups may need to be addressed.
Questions During the Work
Can I see the wire you’re using before it goes into the wall?
This is your opportunity to confirm that the wire gauge matches what was quoted. Ask to see the wire, read the label (14 AWG, 12 AWG, 10 AWG, 8 AWG, 6 AWG), and confirm it matches the circuit specification in your quote. Undersized wire on a circuit is a code violation and a fire risk.
What a good answer looks like: The electrician shows you the wire, reads the label, and confirms it matches the circuit specification.
Can I see the breaker before it goes into the panel?
Before the panel is closed, ask to see the breaker being installed. Confirm the brand matches what was quoted and that the ampere rating matches the circuit being protected. Mismatched breakers — a 20-amp breaker on a circuit wired with 14 AWG wire rated for 15 amps — are a code violation.
What a good answer looks like: A clear view of the breaker, with the brand and ampere rating visible and matching the quote.
Is AFCI or GFCI protection being installed where required?
Ask the electrician which circuits require AFCI (arc-fault) or GFCI (ground-fault) protection under the applicable electrical safety code, and confirm those devices are being installed. AFCI is required on bedroom circuits and increasingly on other living areas; GFCI is required in bathrooms, kitchens, garages, outdoors, and anywhere near water.
What a good answer looks like: A specific list of which circuits have which protection, confirmed against the code requirement.
Are all connections being made inside proper junction boxes?
Electrical connections must be made inside accessible junction boxes — never inside walls, ceilings, or floors without a box. Ask whether all connections are being made in proper boxes and whether those boxes will remain accessible.
Questions If Something Unexpected Comes Up
What did you find, and what does it mean for the job?
In older homes especially, electrical work reveals surprises — knob-and-tube wiring that needs to be isolated, undersized service, grounding issues, aluminum wiring, or double-tapped breakers. When an electrician raises an unexpected finding, ask for a clear explanation of: what they found, what the risk is, what the options are, and what the cost of each option is.
Do I need to approve this before you proceed?
Any work outside the original scope should require your explicit approval — in writing — before it begins and before any additional cost is incurred. Ask directly.
Will this require an amended your local electrical safety authority notification?
If the scope of work changes significantly, your local electrical safety authority notification may need to be updated. Ask whether any discovered issues affect your local electrical safety authority filing.
At the End of the Job
Can you show me what was done before you close everything up?
Before panels are closed, junction boxes are covered, and walls are patched, ask the electrician to walk you through what was done. This is your last chance to see the physical installation — the breakers, the connections, the wire routing. A confident electrician will walk you through it without hesitation.
Is everything tested?
Ask whether all new circuits have been tested under load before the electrician leaves. New outlets should be tested with a circuit tester. New circuits should be verified with the appropriate loads. GFCI outlets should be tested with the test button.
When will your local electrical safety authority inspector be coming?
If an electrical inspection is required, ask when it’s scheduled. You don’t need to be home for every inspection, but you should know when it’s happening and what the inspector will be looking at. Ask the electrician to let you know the result.
