Hi, I’m Peter, Master Electrician with PRO Electric plus HVAC.
Bristow is a community I know well — neighborhoods like Victory Lakes, Braemar, and Avendale are filled with families who want safe, comfortable homes.
Many of these houses were built in the 1990s and early 2000s, during a wave of rapid development.
Here’s the catch: a lot of those homes are still running on their original electrical panels, many of which are 100-amp or 150-amp services.
Back then, that was considered “good enough.” But in 2025?
For many Bristow families, those panels are struggling to keep up with daily life.
Why Bristow Homes Are Feeling the Strain
Built for Yesterday’s Demands
When these panels were installed, builders weren’t thinking about:
- Two or three large HVAC systems
- Home theaters and finished basements
- High-capacity kitchen appliances
- EV chargers pulling 40–60 amps
- Dozens of laptops, tablets, and devices charging around the clock
A 100-amp or even 150-amp panel was fine in the late 1990s.
But Bristow families today are living in homes that ask double or triple the electrical load those panels were designed for.
The Signs of Overload
I get calls from Bristow homeowners with the same symptoms:
- Flickering lights when the AC kicks on
- Overloading from an Infrared Sauna
- Breakers tripping when the oven and microwave run together
- Buzzing or warm panels that indicate hidden stress
- No space left in the panel for a new EV charger or hot tub circuit
The Hidden Risk: Problem Panels in Bristow
While Bristow has fewer older homes than Fairfax or Annandale, I still find dangerous panels like:
- Federal Pacific Stab-Lok: Breakers that sometimes never trip, even under fault.
- Zinsco: Loose breaker connections that cause arcing and melted bus bars.
- Early builder-grade panels: Installed in the 90s and early 2000s, some were undersized or cheaply made. Many are reaching the end of their safe lifespan.
What Bristow Families Risk By Waiting
Fire Hazards
A breaker that fails to trip or a bus bar that overheats isn’t just inconvenient — it’s a fire waiting to happen.
Failing Inspections
If you’re planning to sell, outdated panels will be flagged by home inspectors.
Buyers and insurers are more cautious now than ever about Federal Pacific, Zinsco, and undersized 100-amp panels.
Everyday Frustrations
Tripping breakers, dimming lights, and limited panel space make daily living frustrating. It’s a sign your panel is already at its limit.
How I Evaluate an Electrical Panel in Bristow
Panel Condition
-
Checking brand and model
-
Looking for overheating, arcing, or corrosion
-
Identifying double-lugged breakers or improper wiring
Service Size
- Confirming if the panel is 100, 150, or 200 amps
- Running a load calculation against HVAC, kitchen appliances, and planned upgrades
Grounding and Bonding
- Inspecting grounding rods and water pipe bonding
- Ensuring bonding jumpers are in place and secure
Why a 200-Amp Upgrade is Right for Bristow Homes
More Capacity for Growing Families
With 200 amps, you’ll have the headroom to run HVAC, EV chargers, and all your modern appliances without pushing your system to the brink.
Modern Safety Features
Upgrading allows me to install:
- AFCI breakers for fire protection
- GFCI breakers in kitchens, baths, and outdoor spaces
- Whole-home surge protection to safeguard electronics and HVAC
Peace of Mind and Resale Value
When your home inspector sees a clean, code-compliant 200-amp service, it’s a major selling point.
Buyers know they won’t need to invest in a panel upgrade right after closing.
Stories From Bristow Families
Victory Lakes Townhome
One family called because their dryer and dishwasher tripped the breaker every time they ran together.
Their 100-amp panel was simply maxed out. After a 200-amp upgrade, the problems vanished — and they were finally able to add an EV charger.
Braemar Single-Family Home
This house had a Federal Pacific Stab-Lok panel. The homeowners didn’t know it was dangerous until a breaker refused to trip during an overload.
When I opened the panel, the bus bar showed heavy scorching. We upgraded to 200 amps, corrected grounding issues, and installed surge protection. The family told me they finally felt safe again.

Final Word From Peter
If your Bristow home still has its original 100-amp or 150-amp panel, it’s already living beyond its expected lifespan.
You wouldn’t trust a 30-year-old furnace or roof to protect your family — why rely on a panel that powers everything in your home?
A modern 200-amp service means safety, comfort, and future-proofing for the way your family actually lives.
