Electrical services

The useful split is service-side versus load-side. Service-side means everything from the utility drop to the main breaker: the meter base, the service entrance conductors, the grounding electrode system, and the panel itself. That work involves conductors that stay energized even when your main breaker is off, which is why it needs a licensed electrician and usually a utility disconnect. Load-side is everything past the breaker — circuits, devices, fixtures.

Most homeowner spending falls into three buckets. Diagnostics, where you pay for someone's time to find out why something is failing. Capacity work, where the house cannot carry what you want to plug into it. And code-catch-up work, triggered when you sell, renovate, or an insurer inspects.

A trustworthy electrician will tell you which bucket you are in before quoting. If someone walks in and quotes a full panel replacement without opening the panel, testing anything, or asking what loads you plan to add, get a second opinion. Electrical fires are a real risk — the Electrical Safety Foundation International puts residential electrical distribution systems as the third leading cause of home structure fires — but that risk is also the easiest thing in the trade to use as a scare tactic.

Verify the license before work starts, not after. Electrical licensing is issued at the state level in most states and at the county or city level in some. Ask for the license number and check it on the issuing board's public lookup for your state. Also ask for a certificate of insurance showing general liability and workers' compensation, sent by the insurer, not a photocopy.

How to choose

Match the license class to the job

Journeyman-level electricians can perform the work; a master electrician or licensed electrical contractor usually holds the permit. For panel or service work, confirm who is pulling the permit and that their name is on it.

Insist on a diagnosis before a quote

For anything intermittent — flickering, occasional trips, warm outlets — pay a diagnostic fee and get a written finding. A quote for a fix with no stated cause is a guess you are paying for.

Separate 'unsafe now' from 'not to current code'

Existing work installed legally under an older code edition is generally allowed to remain. That is different from an active hazard. Ask which one you have, in writing.

Get load calculations for new equipment

Before an EV charger, heat pump, hot tub or range install, the electrician should do a service load calculation. If they skip it and just say 'your panel is full,' ask to see the math.

Confirm permit and inspection are included

For panel, service or new-circuit work, the quote should name the permit fee and say the job includes a final inspection. Work done without a permit can complicate a home sale and an insurance claim.

Do not DIY panel or service work

This is not a caution about difficulty. Service conductors are energized upstream of your main breaker, and unpermitted panel work commonly voids coverage and fails at resale.
