100 Amp to 200 Amp Service Upgrades

If your home still has a 100 amp electrical service, there is a good chance it is being asked to do more than it was built for. Modern homes use more power every year. Central air, electric water heaters, kitchen appliances, home offices, hot tubs, EV chargers, workshops, and smart home equipment all add demand. At Pro Town Electric, we provide 100 amp to 200 amp service upgrades to give your home the power capacity, safety, and reliability it needs now and for the years ahead.

A service upgrade is one of the most important electrical improvements you can make to a home. This is not just a panel swap. A true 100 amp to 200 amp upgrade usually involves replacing or updating the main electrical panel, meter base when required, service entrance cable, grounding and bonding system, main disconnect, and other service equipment so the entire electrical service can safely handle a higher load. We look at the full system and make sure every part works together the right way.

Why homeowners upgrade from 100 amps to 200 amps

Many older homes were built when electrical demand was much lower. Back then, there were fewer large appliances and fewer dedicated circuits. Today, that same home may be trying to support multiple televisions, computers, kitchen devices, HVAC equipment, laundry machines, and newer additions like electric vehicle charging. If your service is undersized, you may notice warning signs that your electrical system is under strain.

Common reasons to upgrade include:

• Adding central air conditioning or heat pump equipment
• Installing an EV charger
• Remodeling a kitchen, basement, garage, or addition
• Adding a hot tub, sauna, workshop, or outdoor living area
• Replacing gas appliances with electric models
• Frequent breaker trips or lack of space for new circuits
• Planning ahead for future electrical needs
• Meeting insurance or utility requirements on an older home

In many cases, a 200 amp service gives a homeowner more flexibility and peace of mind. It can also improve day-to-day performance by reducing overload issues and giving room for proper circuit distribution.

What is included in a 100 amp to 200 amp service upgrade

Every property is a little different, but our service upgrades are designed to address the full electrical service, not just one visible part. We start by evaluating the existing equipment, the condition of the panel, available circuit space, service wire size, grounding, and the overall power demands of the home. From there, we recommend the proper scope of work.

A typical upgrade may include:

• Removal of the existing 100 amp service equipment
• Installation of a new 200 amp main breaker panel
• Replacement of the meter socket or meter base if required
• New service entrance conductors
• New weather head, mast, or service riser when needed
• Grounding electrode system upgrades, including ground rods and bonding
• Main bonding and neutral separation where code requires
• Circuit identification and panel labeling
• Coordination with the utility company for disconnect and reconnect
• Permit handling and electrical inspection

Our goal is to leave you with a safe, code-compliant electrical service that is ready for current loads and future upgrades.

How we determine if a 200 amp service is right for your home

Not every home needs the same electrical capacity. That is why we do not treat service upgrades like a one-size-fits-all job. We look at your current usage, major appliances, HVAC system, square footage, and any planned additions or equipment. We may perform a load calculation to determine whether a 200 amp service is the right fit. This helps make sure your upgraded service matches the actual electrical demand of the property.

We also check for practical concerns such as panel location, existing wiring conditions, utility requirements, access issues, and whether there are code updates that need to be addressed during the work. If there are problems with the old panel, corroded components, crowded breakers, or outdated grounding, we will explain what we find and what needs to be corrected.

Signs your current 100 amp service may be too small

• Breakers trip when several appliances run at the same time
• Lights dim or flicker when large equipment turns on
• Your panel is full and has no room for additional circuits
• You rely on extension cords or power strips in several areas
• You are adding new electric appliances or a home addition
• Your home has an older fuse box or outdated electrical panel
• Your utility or insurance provider has flagged the service equipment

These signs do not always mean an upgrade is the only answer, but they often point to capacity or safety issues that should be reviewed by a licensed electrician.

The benefits of upgrading to 200 amp service

A properly installed 200 amp electrical service can bring several important benefits to your home:

• More power capacity: Support modern appliances and equipment without overloading the system.
• Improved safety: Older service equipment can wear out over time. An upgrade can replace aging parts and bring the service up to current code standards.
• Room for expansion: A larger panel gives you space for additional circuits for remodeling, EV charging, outbuildings, and more.
• Better reliability: Reduce nuisance breaker trips and electrical strain.
• Increased home value: A newer 200 amp panel is often seen as a strong upgrade by buyers and inspectors.
• Future-ready electrical system: Prepare for electric appliances, smart home upgrades, battery backup, or solar-related improvements.

For many homeowners, the upgrade is about more than just capacity. It is about confidence that the electrical system can keep up safely.

Our service upgrade process

At Pro Town Electric, we believe electrical work should be straightforward and well planned. We walk you through the process so you know what to expect.

1. Initial evaluation: We inspect the current service, panel, meter setup, grounding, and overall condition of the system.
2. Load review and recommendations: We discuss your current power usage and future plans, then recommend the right upgrade scope.
3. Estimate and scheduling: We provide clear information about the work involved and schedule the project at a practical time.
4. Permits and utility coordination: We handle required permits and work with the utility company on the disconnect and reconnect process.
5. Installation: We replace the necessary service equipment, upgrade grounding and bonding, and organize circuits in the new panel.
6. Testing and inspection: We test the system, verify proper operation, and complete the required inspection.
7. Final walk-through: We explain the new panel layout, answer questions, and make sure you are comfortable with the finished work.

Because service upgrades involve the main power supply to your home, some temporary outage is expected during the switchover. We plan the work carefully to keep disruption as limited as possible.

Important code and safety considerations

Main service upgrades must be done correctly. This work involves utility power, service conductors, grounding, bonding, breaker sizing, panel ratings, and local code compliance. Small mistakes can create serious hazards, including overheating, shock risk, equipment damage, or failed inspections. That is why this is work for trained, licensed professionals.

Our certified electricians follow current electrical code requirements and industry best practices. We pay close attention to details like conductor sizing, grounding electrode connections, proper breaker selection, neutral and ground separation where required, working clearances, surge protection options, and accurate circuit labeling. We do not cut corners. We do the work the right way so your electrical service is safe and dependable.

Common upgrade situations we handle

• Older homes with original 100 amp panels
• Homes with fuse boxes being converted to breaker panels
• Service upgrades before a major remodel
• Electrical preparation for EV chargers
• Homes adding new HVAC or electric heating equipment
• Panel upgrades required for hot tubs, pools, or detached structures
• Replacement of damaged, rusted, or outdated service equipment

If you are not sure whether your home needs a full service upgrade or a panel replacement, we can inspect the system and explain the difference. In some homes, the issue is circuit space. In others, the entire service is undersized. We help you make the right call based on safety, code, and long-term value.
