WHAT IS A 100 AMP PANEL?
What Is a 100 Amp Panel Upgrade and Do You Need One in Las Vegas?
A 100 amp panel is a standard electrical service size that provides enough power for smaller homes with basic appliances, a single AC unit, and no major high-demand equipment like an EV charger or pool. A 100 amp panel upgrade in Las Vegas typically replaces an old fuse box or a failing, outdated panel with a modern, code-compliant circuit breaker panel.
Unlike a 200 amp upgrade, which is built for homes with heavy electrical demand, a 100 amp panel upgrade is the right, cost-effective choice when your home's electrical needs are modest and unlikely to grow significantly. It still gives you the safety benefits of a modern circuit breaker system - properly rated breakers, AFCI and GFCI protection, and a panel that meets current Clark County code.
You likely need a 100 amp panel upgrade in Las Vegas if: you still have an old fuse box, your current panel is undersized or failing, or you have a smaller home with no plans for an EV charger, pool, or major addition. For homes with higher demand, we typically recommend a 200 amp upgrade instead - our licensed electricians will assess your home and give you an honest recommendation either way.
⚡ Safer Than a Fuse Box
Replacing an old fuse box with a modern 100 amp breaker panel eliminates a major fire and shock hazard. Breakers trip safely on overload; fuses can be a hidden danger.
🛡️ Fully Permitted and Code-Compliant
Every 100 amp panel upgrade we perform in Las Vegas is fully permitted with Clark County and inspected, so you have documentation and legal protection for the work.
📈 Cost-Effective for Smaller Homes
If your home doesn't need the extra capacity of a 200 amp service, a 100 amp panel upgrade gets you a safe, modern panel without paying for capacity you won't use - without a second visit from a Las Vegas electrician later if your needs stay the same.

Do You Need an Upgrade?
Common 100 Amp Panel Upgrade Projects in Las Vegas
These are the most common reasons Las Vegas homeowners call us for a 100 amp panel upgrade. If any of these apply to you - a 100 amp panel upgrade is likely the right solution.
Replacing an Old Fuse Box
The most common 100 amp panel upgrade in Las Vegas. We remove the old fuse box completely and install a modern, code-compliant 100 amp circuit breaker panel - safer and easier to use.
Homeowner's Insurance Requirements
Many Las Vegas insurance companies now require a modern circuit breaker panel as a condition of coverage. A 100 amp panel upgrade brings your home up to current safety standards and can help you secure or renew coverage.
Frequent Breaker Trips
If your panel trips constantly or breakers won't reset reliably, your panel is failing or undersized. A 100 amp panel upgrade replaces worn-out components with a fresh, properly rated panel.
Selling or Refinancing Your Home
Las Vegas home inspectors and buyers flag outdated panels during the sale process. A new 100 amp panel with a clean permit history removes this red flag and protects your sale timeline.
Older Home Rewiring Projects
Older Las Vegas homes undergoing a partial rewire or renovation often need a 100 amp panel upgrade first, since the existing panel can't safely support new circuits or modern code requirements.
Smaller Homes With Modest Demand
If your Las Vegas home has basic appliances, a single AC unit, and no EV charger or pool planned, a 100 amp panel upgrade is the right, cost-effective choice instead of paying for unneeded 200 amp capacity.
