Electrical Panel Upgrades in Troy, MI
A 100-amp service panel was adequate for a home built in 1975 that ran a gas furnace, a few kitchen appliances, and incandescent lighting. It is not adequate for a home that now runs central air conditioning, an EV charger, an electric range, and multiple home office setups simultaneously. Panel overloads cause breakers to trip repeatedly, create heat buildup in the enclosure, and represent a genuine fire risk if the panel is one of the older brands with documented design problems.
Signs a panel upgrade is warranted in a Troy home:
- Breakers trip under normal household load conditions
- The panel is a Federal Pacific Stab-Lok or Zinsco brand, which have documented reliability failures
- Adding a new major appliance, EV charger, or HVAC system requires more capacity than available slots can accommodate
- The home still uses fuses rather than breakers, indicating original pre-1970s electrical service
- Double-tapped breakers are present, a code violation indicating the panel is already beyond capacity
Upgrading to 200-amp service is the standard recommendation for most Troy homes adding significant new load. The work involves a service entrance upgrade, a new meter base (requiring utility coordination), and a new panel with a load calculation to confirm required capacity. See circuit breaker and panel service.
EV Charger Installation in Troy, Michigan
Troy has one of the higher EV ownership rates in Southeast Michigan, driven by proximity to automotive and technology employers and a household income profile that supports early adoption. A Level 1 charger on a standard 120-volt outlet adds 3 to 5 miles of range per hour. A Level 2 charger on a dedicated 240-volt, 50-amp circuit adds 20 to 30 miles per hour and fully charges most electric vehicles overnight.
What EV charger installation typically involves in a Troy home:
- Panel evaluation to confirm adequate capacity for a dedicated 50-amp circuit
- Panel upgrade if the current service is already near capacity or is 100-amp service
- Wiring run from the panel to the garage, which in Beach Forest or Baileys Vineyards homes may involve conduit through finished living space
- EVSE installation, circuit testing, and connection verification
Smart chargers compatible with off-peak utility rate scheduling are available as part of the installation. See EV charger installation detail.
Whole-Home Generator Installation in Troy
Southeast Michigan experiences extended power outages from ice storms, high-wind events, and summer thunderstorm activity. For Troy homeowners with finished basements housing HVAC equipment, sump pumps, and home offices, an outage lasting more than a few hours becomes a significant problem. Whole-home standby generators run on natural gas, transfer automatically on utility loss, and restore power to the entire home within seconds of an outage, without any manual intervention. See generator installation and service for equipment options and the installation process.
Electrical Repair & Wiring in Troy
Older Troy homes present common repair needs: outlets that no longer hold plugs securely, GFCI failures in kitchens and bathrooms, aluminum branch wiring from 1970s construction that requires remediation at all termination points, and switches with worn contacts. All electrical repair work is performed by licensed electricians and permitted where required by Oakland County. See electrical repair services and outlet and switch installation.
Lighting, Surge Protection & Electrical Installation in Troy
Lighting upgrades are a common request in Troy’s high-value residential market: recessed LED conversions, exterior fixture replacements, under-cabinet lighting, and landscape lighting. Whole-home surge protectors protect appliances and electronics from voltage spikes on the utility line, which is relevant for any Troy home running a home office with expensive equipment. For complete electrical installation and lighting installation services, see the respective pages.
Frequently Asked Questions: Electrical Services in Troy
We’ve built our reputation on honesty, quality, and reliability — but don’t just take our word for it.
Do I need a panel upgrade to install an EV charger?
Not always, but often. A Level 2 charger requires a dedicated 50-amp, 240-volt circuit. If the existing panel has available space and capacity, the circuit can be added directly. If the panel is already near capacity or is 100-amp service, an upgrade is typically required first. See EV charger installation.
How much does an electrical panel upgrade cost in Troy?
A 200-amp panel upgrade in a Troy home typically runs $1,500 to $3,500, depending on service entrance accessibility, Oakland County permit requirements, and whether the meter base requires utility coordination. Homes with aluminum service entrance conductors may require additional work beyond the panel itself.
What is aluminum branch wiring and is it a safety issue?
Aluminum branch circuit wiring was common in residential construction from the mid-1960s through the 1970s. Some older Troy homes still have it. Aluminum wiring expands and contracts more than copper under load, which can loosen connections over time and create overheating risks at outlets, switches, and fixtures. COPALUM crimping or AlumiConn connectors at all termination points is the standard remediation. A licensed electrician can assess the scope.
How long does generator installation take?
A whole-home standby generator installation typically takes one to two days for the physical work, plus permitting and utility notification time. Troy and Oakland County require permits for standby generator installations. Utility disconnection and reconnection adds time in some cases.
Can you install outdoor lighting for landscaping or driveways?
Yes. Low-voltage landscape lighting and line-voltage exterior fixture installations are both available. Line-voltage outdoor lighting requires a licensed electrician. See lighting installation.
What does a whole-home surge protector actually protect?
A whole-home surge protector installed at the panel intercepts voltage spikes on the utility line before they reach appliances and electronics throughout the house. It does not protect against a direct lightning strike but does address the indirect surges from nearby strikes and the smaller transient spikes from utility switching events. See surge protection detail.
My lights dim when the AC kicks on. Should I be concerned?
Brief dimming when a large load starts is normal. Sustained flickering or significant dimming throughout the home indicates a loose connection at the service entrance, a failing main breaker, or a voltage drop issue. Have it evaluated. It is the kind of problem that gets worse, not better, on its own.
Do you handle electrical work for home additions or renovations in Troy?
Yes. New construction wiring, service additions, and renovation electrical are handled by Davison’s licensed electricians. Troy building permits are required for most electrical work in additions and renovations. See electrical installation services, or call (248) 781-0305 to discuss the project scope.
