ELECTRICAL PANEL UPGRADES
Future-proof your home's capacity and remove fire hazards safely.
ELITE, CODE-COMPLIANT CRAFTSMANSHIP
Federal Pacific, Zinsco, and older split-bus panels pose severe fire hazards. We upgrade outdated 100-amp service panels to modern 200-amp panels to support heavy cooling, EV charging, and modern HVAC systems.
Your home’s electrical panel, often called the breaker box or service panel, is the central distribution point for all electrical current in your property. As residential energy demands have skyrocketed over the past few decades due to multi-zone air conditioning systems, electric vehicle chargers, hot tubs, and heavy-draw kitchen appliances, older panels are simply unable to keep pace. Operating an older 100-amp panel at near-maximum capacity causes the bus bars to heat up, degrading breaker contacts and leading to hidden mechanical failures. Furthermore, outdated split-bus panels, which lack a single main breaker to shut off all power, violate modern safety codes. We perform complete service panel upgrades, replacing outdated setups with modern, commercial-grade 200-amp panels that provide clean, safe, and reliable electrical distribution for your entire home.
Why Choose Mister Wright for Electrical Panel Upgrades?
Complete Utility & Permit Management:
Upgrading a service panel requires strict coordination with municipal inspectors and local power utilities (such as SRP or APS). We handle all building permits, schedule the utility disconnect/reconnect times, and manage the final inspection so you don’t have to deal with the bureaucracy.
Calibrated Torque Testing:
To guarantee long-term safety, we torque every single breaker terminal screw and bus bar connection to the manufacturer’s exact specifications using calibrated tools, preventing thermal hotspots.
Premium Hardware Only:
We only install heavy-duty, copper-bus panels from leading brands like Eaton (CH Series) or Square D (QO Series). These panels offer superior conductivity, mechanical durability, and faster breaker trip speeds compared to budget-grade panels.
Upfront Flat-Rate Estimates:
A panel upgrade is a major home investment. We provide an exact, upfront flat rate covering all materials, labor, permits, and utility coordination—with absolutely zero hidden fees.
The $99 Waived-With-Repair Guarantee
Our diagnostic fee is a transparent $99. If you go ahead with our recommended electrical resolution, that diagnostic fee is completely waived!
THE 4-STEP WRIGHT PROCESS
We remove the guesswork and stress from home electrical work. Here is how we ensure perfect, code-compliant safety.
Load Study & Permit Filing
We perform load calculations, submit schematics to local municipal authorities, secure building permits, and coordinate disconnect schedules with SRP or APS.
Old Service Box Extraction
We extract the old panel, label all circuit conductors, and prepare the main service entrance conduit for modern, heavy-duty wire gauges.
Service Panel Installation
We mount the new copper-bus enclosure, install a 200-amp main breaker, wire the branch circuits, and torque all connections to exact manufacturer specs.
Grounding & Final Inspection
We install dual ground rods, bond the domestic plumbing system, label the panel clearly, and coordinate the final inspection with the city inspector to restore permanent utility power.
Why Code-Compliance Matters
Federal Pacific and Zinsco panels have documented failure rates exceeding 50% for failing to trip during overloads, heating up hidden wiring. A service change eliminates this risk instantly. Every installation we perform is led by Master Electrician Saul Rios, ensuring it is fully insured, bonded, and backed by a comprehensive safety audit that complies 100% with the latest National Electrical Code guidelines.
Before upgrading any service, we perform a comprehensive load calculation based on NEC Article 220. This ensures your service is properly sized. We factor in the square footage of the home (3 watts per sq. ft.), two dedicated 20-amp laundry/appliance circuits, and the exact nameplate draw of all major appliances (AC units, ranges, dryer, EV chargers). Upgrading the panel also means updating your grounding system to comply with current codes. Modern code requires driving two copper-clad ground rods spaced at least 6 feet apart into the earth, bonded with a continuous #4 AWG bare copper wire. Additionally, we must bond your metal interior water piping and gas lines to the main service ground to prevent static voltage build-up and ensure that any short circuit trips the breaker instantly rather than energizing your plumbing fixtures.
FAQ Specific to Electrical Panel Upgrades
What is the difference between a 100-amp and a 200-amp panel?
A 100-amp panel provides 24,000 watts of electrical capacity, which is easily exhausted by a modern home running a central air conditioner, clothes dryer, and kitchen appliances. A 200-amp panel provides 48,000 watts of capacity, allowing you to run multiple heavy-load appliances, EV chargers, and HVAC systems simultaneously without overloading the service.
Why are Federal Pacific and Zinsco panels considered dangerous?
Federal Pacific (FPE) 'Stab-Lok' and Zinsco panels have a high manufacturing failure rate. Under load, their breakers frequently fail to trip during an overload or short circuit, causing current to flow unchecked. This heats up the wiring and can cause hidden fires. Many insurance companies will refuse to write policies for homes containing these panels.
Do I need a new panel to install a Level 2 EV charger?
Not necessarily, but it depends on your current load calculation. If you have a 100-amp panel and a gas water heater/dryer, you might have room. If your home runs all-electric appliances and AC, you will likely need to upgrade to a 200-amp panel to add a 50-amp charger safely without overloading the system.
What is whole-home surge protection, and is it required?
Yes, under NEC Article 242, whole-home surge protection devices (SPDs) are now required on all new or upgraded service panels. These devices are installed directly inside your main panel and redirect high-voltage surges (from lightning or grid switching) safely to the ground, protecting your smart appliances and electronics.
How long will my power be out during a panel upgrade?
On the day of installation, your power will typically be turned off for about 4 to 6 hours. We coordinate the utility shut-off and reconnect times very closely to minimize downtime. We also utilize on-site generators to run critical items or lights if needed during the swap.
