What’s the purpose of the Prepare step, and give one example of how you personally do it before a call.
To set yourself up for success by being ready and confident; example: reviewing customer notes, organizing tools, or rehearsing mindset.
What’s the required working clearance depth in front of a 120/240 panel?
36 Inches (NEC 110.26)
What’s the maximum continuous load you can place on a 20A circuit in a house?
16 amps (80% of rating).
In the Greet step, what’s one thing you can say or do to immediately set a positive tone with a skeptical homeowner?
Smile, use their name, show respect for their home (shoe covers, polite greeting).
What’s the minimum burial depth for residential direct-burial UF cable under dirt?
24 inches.
A customer complains their lights dim whenever the microwave runs. What’s the most likely electrical cause?
Voltage drop from an overloaded or undersized circuit.
During the explore step, why is it more effective to ask questions instead of telling the customer what’s wrong?
Questions help the customer connect the dots themselves, which builds trust and reduces resistance.
What NEC article requires arc-fault protection for outlets in bedrooms?
NEC 210.12
You open a panel and see a double-lugged neutral under the same terminal. Why is this a problem?
It can cause loose connections, overheating, and violates NEC 408.41 (one neutral per terminal).
Presentation step, what’s one strategy you can use to build value in the higher options so the customer doesn’t automatically choose the cheapest?
Highlight safety, longevity, warranties, or added benefits in higher options (example: “This option not only fixes today’s issue but also prevents future failures, saving you money long-term”).
What is the maximum number of disconnects allowed for one service under the 2023 NEC?
Six disconnects
A homeowner has a detached garage. What’s required for grounding at the garage if it has a sub-panel?
A 4-wire feeder (hot, hot, neutral, ground) and a separate grounding electrode system at the garage.
In the present, what’s the best way to handle an objection without sounding defensive or pushy?
Acknowledge the concern, restate the value, and redirect with empathy (ex: “I understand budget is important, that’s why we made sure to give flexible solutions”).
Can neutrals and grounds share the same bar in a sub-panel?
They must be isolated.
A homeowner calls about breakers tripping randomly throughout the house. What could a floating neutral cause, and how would you test it?
It can cause fluctuating voltages (some circuits overvoltage, others undervoltage). Test with a meter under load between hot-neutral and hot-ground.
