Why Homeowners Move From 100 Amp To 200 Amp
A 100 amp panel was enough decades ago. Modern homes use more power. Air conditioning, electric ovens, dryers, hot tubs, EV chargers, and finished basements add up fast. A 200 amp service increases available capacity and reduces nuisance trips.
Common reasons to upgrade:
- Frequent breaker trips or warm panel cover.
- Lights dim when major appliances start.
- Plans for EV charging or a standby generator.
- Additions, remodels, or converting gas to electric.
- Insurance or inspection flagged the panel.
Result you can expect:
- More circuits with room to grow.
- Better reliability under peak loads.
- Compliance with current electrical code and labeling.
What A 200 Amp Service Upgrade Includes
A proper upgrade is more than swapping a box. It is a system change from the utility connection to the grounding.
Typical scope:
- Site evaluation and load calculation.
- Permit and utility coordination.
- New 200 amp meter base and service entrance conductors.
- New 200 amp main breaker panel with labeled circuits.
- Correct grounding and bonding upgrades.
- Arc fault and ground fault protection, where required.
- Surge protection option for whole‑home safety.
- Inspection and final utility release.
Our licensed electricians also perform safety evaluations, circuit testing, and efficiency upgrades. No work starts without your approval, and payment is collected after the job is completed to your satisfaction.
Indianapolis and Surrounding Cities: Permits, Power Company, and Inspections
In Indianapolis, electrical service upgrades require a permit and inspection. We handle the paperwork with the City of Indianapolis Department of Business and Neighborhood Services. For most metro addresses, we coordinate with AES Indiana for service disconnect and reconnect scheduling. In surrounding cities like Carmel, Fishers, Noblesville, Greenwood, Zionsville, Avon, Westfield, Brownsburg, and Plainfield, we follow each jurisdiction’s permit process and the serving utility’s requirements.
Why it matters:
- Safe disconnect and reconnect keeps the timeline tight.
- Approved meter base and service mast heights avoid failed inspections.
- Proper grounding and labeling support insurance and future resale.
Is 200 Amp Enough For Today and Tomorrow?
For most single‑family homes, 200 amps is the right sweet spot. It supports common combinations like central AC, electric range, dryer, dishwasher, microwave, and a future EV charger.
Plan for known upgrades:
- One 40–60 amp EV charger circuit is typical. Many models work well on 40 amps.
- Electric range and oven often need 40–50 amps.
- Heat pump or mini splits vary. Check nameplates.
- Hot tubs often need 50 amps with GFCI protection.
During your load calculation we add realistic diversity so you get capacity without overspending.
Signs Your 100 Amp Service Is Holding You Back
You might not need special tools to spot the clues.
- Panel is full or has tandem breakers stacked everywhere.
- Breakers are hard to reset, warm, or noisy.
- Lights dim when HVAC or microwave starts.
- You hear arcing or buzzing.
- Old or recalled equipment like certain Pushmatic or obsolete brands.
If you see scorch marks, loose covers, or smell burning, call us right away. Safety first.
What Happens On Installation Day
- We arrive on time and review the plan with you.
- Protect floors and clear work areas near the panel and meter.
- Shut down power when the utility is ready.
- Replace meter base, service mast or lateral conductors as needed, and install the new 200 amp panel.
- Reconnect circuits, label every breaker, and install surge protection if selected.
- Perform safety tests and cleanup.
- Inspection and power restoration follow the approved schedule.
Most upgrades finish the same day, depending on utility timing and inspection windows.
Safety, Code, and Labeling Details That Matter
There is more to safety than a larger main breaker.
- Grounding and bonding must be correct at the new service. We verify grounding electrodes and bonding jumpers.
- Kitchens, baths, laundry, garages, and outdoors require GFCI protection in defined locations.
- Many living spaces require AFCI protection. We meet current local adoption of code.
- Clear working space in front of the panel is required for safe access.
- Accurate, permanent labeling helps every future project go smoother.
Our team installs neat, organized panels and labels each circuit, which homeowners consistently praise.
200 Amp Panel Options and Add‑Ons
You can keep it simple or add protection and smart features.
- Standard main breaker panel with copper or aluminum bus options.
- Whole‑home surge protector to defend appliances and electronics.
- Combination AFCI and GFCI breakers where needed.
- Generator interlock kit or transfer switch for standby power.
- Subpanel for workshops, finished basements, or additions.
We help you choose what fits your home and budget.
Future‑Proofing For EV Chargers And Generators
Panel capacity drives everything. During your upgrade assessment we check EV charging plans and generator readiness.
- EV charger assessment ensures your 200 amp panel and feeder sizing will support a 40–60 amp circuit without nuisance trips.
- Standby generator planning includes transfer equipment, neutral regulation needs, and load shedding options.
- Clear labeling of EV and generator breakers simplifies maintenance.
This is the best time to run conduit, reserve spaces, and set up the transfer infrastructure.
Cost Factors For A 200 Amp Service Upgrade
Every home is different. Pricing depends on scope and site conditions.
Common drivers:
- Overhead vs. underground service. Underground often requires coordination and trenching.
- Meter base location, service mast height, and utility clearance.
- Panel relocation, drywall repair, or line length changes.
- Grounding upgrades and replacement of outdated feeders.
- Permit, inspection, and utility fees.
- Add‑ons like surge protection, subpanels, or generator readiness.
We provide clear pricing up front, explain options, and apply any available promotions. Members of our Shape Plan save 10 percent on repairs and receive priority scheduling. The plan includes an Electrical Pitstop, a checkup valued at $89.
Timelines You Can Expect
Planning helps avoid surprises. A typical path:
- Same‑ or next‑day assessment and quote.
- Permit submission within one business day after approval.
- Utility scheduling for disconnect and reconnect. Timing varies by utility load.
- Installation usually completed in one day once the utility window is set.
- Inspection and power restoration the same day when feasible.
We coordinate with AES Indiana and nearby utilities so your downtime is as short as possible.
How To Prepare Your Home For The Upgrade
A little prep speeds the day and keeps dust down.
- Clear 3 feet in front of the panel and path to the meter.
- Unplug sensitive electronics or use a surge strip.
- Plan for a brief outage. Keep fridge closed and doors shut in summer or winter.
- Crate pets and secure gates.
We protect floors, work clean, and haul away debris.
Choosing The Right Electrician For The Job
Service upgrades are not a handyman project. You want a licensed, insured team with permits, inspections, and utility coordination included. Ask these questions:
- Are you licensed and insured for electrical service work?
- Will you handle permit, inspection, and utility scheduling?
- What is included in grounding and labeling?
- Do you offer whole‑home surge protection and generator options?
- Can I see reviews for similar panel projects?

Can I DIY An Upgrade From 100 To 200 Amps?
No. Service upgrades require a licensed electrician, permits, and utility coordination. The risks include shock, fire, and denied insurance claims. A failed inspection can delay power restoration and cost more than hiring a professional in the first place.
Upgrade 100 Amp To 200 Amp Service: A Simple Decision Framework
Use this checklist to decide in minutes:
- List your major loads: HVAC, range, dryer, water heater, hot tub, EV.
- Count open panel spaces. Tandems are a warning sign, not a solution.
- Note symptoms: dimming, tripping, warm breakers, buzzing.
- Confirm future plans: EV, remodel, finished basement, or generator.
- Get a licensed evaluation and load calculation.
If two or more items raise concern, it is time to upgrade 100 amp to 200 amp service.
Integrated Upgrades That Pair Well With A 200 Amp Panel
Maximize the value of the project by bundling work while the panel is open:
- Whole‑home surge protection to protect HVAC and electronics.
- Dedicated circuits for microwaves, sump pumps, freezers, and offices.
- AFCI upgrades in living areas for safety and code compliance.
- Subpanel for garages or workshops to simplify future projects.
- GFCI upgrades for kitchens, baths, laundry, garages, and outdoors.
These changes are faster and cleaner when done during the service upgrade.
