Real answers from a working electrician
Clear, factual explanations of what's behind your electrical panel doors: what the work involves, what the National Electrical Code (NEC) requires and why it affects cost, and what's worth understanding about your own electrical system before you decide what your home needs. Written by Jesse Dunlap, a Colorado Licensed Master Electrician in the trade since 1998. No fear-marketing, just straight answers.
Circuit Protection
The breakers a modern panel needs: arc-fault circuit interrupters (AFCI), ground-fault circuit interrupters (GFCI), and surge protection. What each one protects against, why the 2023 NEC requires them, and what that means for the cost of a new panel.
Arc-Fault (AFCI) Protection
What arc-fault breakers detect, the fires they prevent, and why nearly every circuit in a new panel needs one.
Ground-Fault (GFCI) Protection
How ground-fault protection prevents shock in kitchens, baths, garages, and outdoors, and where code requires it.
Whole-Home Surge Protection
Why surge protection moved into the panel, what it guards against, and what it does not.
AFCI Nuisance Tripping
When an arc-fault breaker keeps tripping: telling a real fault from a nuisance trip, and what to do about it.
Permits & Code
What the permit and inspection process protects you from, and how to confirm the person doing the work is licensed.
EV Charging
What home charging actually involves: the charging levels, whether your panel can carry the load, and why the install details matter on the Front Range.
