Have Questions About Your  Electrician?


Common Questions

Frequently Asked Questions

  • How does a generator interlock kit keep backup power safe?

    An interlock kit prevents the main breaker and the generator breaker from being on at the same time. That stops backfeeding onto utility lines, protecting line workers and your equipment while letting a portable generator power selected household circuits.

  • Should wiring to a backyard pool or spa be run underground?

    Underground conduit is common for pools, hot tubs, and swim spas because it keeps wiring protected and out of sight. Burial depth, conduit type, and routing must follow code, and the path should avoid patios and future landscaping plans.

  • Do I need to be home for the county electrical inspection?

    Often, yes, if the inspector needs access inside the house, panel, or garage. Exterior-only work may not require your presence. We coordinate inspection timing and let you know in advance what access the inspector will need.

  • Half of my house lost power. What could cause that?

    Losing power to half the home often points to a problem with one leg of the incoming service, a failing main breaker, or a loose connection at the meter or panel. Treat it as urgent and call for prompt diagnosis.

  • My GFCI outlet will not reset. Does it need replacing?

    A GFCI that will not reset may have no power reaching it, a ground fault downstream, moisture in an outdoor box, or a failed device. Testing the circuit shows whether the outlet or something connected to it is the problem.

  • Are smart switches and dimmers worth installing?

    Smart switches and dimmers let you schedule lighting, control it remotely, and set scenes, which adds convenience and can improve security while you are away. Many require a neutral wire, so checking existing switch boxes comes first.

  • Would you fix electrical work left unfinished or done incorrectly by another contractor?

    Yes. We regularly correct problems left behind by others, from loose connections and missing protection to code violations found during inspections. We evaluate the existing work, explain what needs to change, and provide honest pricing before starting repairs.

  • When is an electrical problem urgent enough for an emergency call?

    Call right away for sparking outlets, buzzing or hot panels, partial or total power loss, water near electrical equipment, or wiring damaged by storms. With 24/7 service, CMB Electrical Services can respond quickly to make the situation safe.

  • Which appliances need their own dedicated circuit?

    Refrigerators, microwaves, dishwashers, garbage disposals, washers, dryers, electric ranges, water heaters, HVAC equipment, hot tubs, and EV chargers typically need dedicated circuits. Separate circuits prevent overloads, nuisance tripping, and overheating when several appliances run at once.
