Question 1

Is the power off at the breaker, and is it safe right now?

Accepted Answer

If you smell burning or see sparks, kill the breaker for that circuit (or the main if you're not sure which one) and tell the electrician what happened.

Question 2

Has a breaker tripped, or are you fully without power?

Accepted Answer

A single tripped breaker usually points to a circuit issue. Whole-house outage may be an incoming-supply or panel problem — useful info for the pro.

Question 3

How old is your electrical panel?

Accepted Answer

If your panel is 25+ years old or aluminium-wiring era, mention it. Some repairs require a panel upgrade first.

Question 4

Did anything happen right before the issue started?

Accepted Answer

A storm, water leak, or new appliance install often triggers electrical faults. Context narrows down the diagnosis.

Question 5

Are there pets or kids you need the pro to know about?

Accepted Answer

Open panels and exposed wiring are dangerous. Tell the electrician so they can plan workspace around little hands and curious noses.

Question 8

What is a Circuit breaker panel?

Accepted Answer

The main electrical panel that distributes power to circuits and contains breakers that trip when a circuit is overloaded. Panel upgrades are often needed when adding capacity or in older homes.

Question 9

What is a Sub-panel (electrical)?

Accepted Answer

A sub-panel is a secondary electrical distribution panel fed from the main service panel. Sub-panels are added when a home runs out of breaker spaces, when a long distance from the main panel makes new circuits impractical, or when a detached structure (garage, workshop, ADU) needs its own breakers. The sub-panel is connected to the main panel by a 4-wire feeder (two hots, one neutral, one ground) sized for the sub-panel's amperage rating — commonly 60, 100, or 125 amps. The critical code requirement that distinguishes a sub-panel from a main panel: in a sub-panel, the neutral and ground bars must be separated, not bonded together. The neutral connects only to the neutral bar (which is isolated from the panel enclosure), while the equipment grounding conductor connects to the ground bar (which is bonded to the enclosure). This separation prevents parallel current paths that can cause shocks and equipment damage. Installation requires a permit and a licensed electrician — costs run $1,000–$3,500 depending on amperage, distance from the main panel, and whether trenching is needed for outbuildings.

Question 10

What is a Load center (electrical panel)?

Accepted Answer

The modern industry term for a residential electrical panel — the metal enclosure where the main breaker and branch circuit breakers are housed, distributing electricity from the utility feed to individual circuits throughout the home. A load center is rated by amperage (100A, 150A, 200A, or 400A) and number of spaces/circuits (20-space/40-circuit to 42-space/84-circuit, with tandem breakers allowing two circuits per space). Current standard for new homes is 200A/40-space; homes with EV chargers, heat pumps, or electric ranges often need 200A minimum, and all-electric homes may require 400A or a load-management panel. Leading manufacturers: Square D (Schneider Electric), Eaton, Siemens, and Leviton (smart panels). A standard 200A panel upgrade from an older 100A or fuse box: $1,800–$4,500 including permit, utility coordination, and inspection. Smart load centers (Leviton Smart Load Center, Span Panel at $3,500–$6,000) add per-circuit monitoring, remote control, and EV/solar/battery integration through a companion app. All load center work requires a licensed electrician and permit in every US jurisdiction. When upgrading, the electrician must also bring wiring up to current NEC code at the panel — AFCI breakers for bedrooms, GFCI for wet areas, and proper grounding/bonding.
