Panel upgrades: 100 vs 200 vs 400 amps

The panel is the heart of the system, and amperage is its capacity. A 100-amp panel was standard for mid-century homes running lights, a fridge, and little else. A modern home with central air, an electric dryer, and one EV charger wants 200 amps; add a heat pump, induction range, hot tub, and a second EV and the NEC Article 220 load calculation starts pointing at 400.

A 100→200A upgrade ($2,000–$4,000) includes the panel cabinet, all breakers, grounding electrode work, labeling, permit, and utility coordination for the disconnect/reconnect. What it often does not include: a new meter socket ($300–$600), a new service mast or riser ($400–$800), or touching any branch circuits. A 400A service ($4,500–$8,000) is usually implemented as two 200-amp panels with a 400-amp meter base — ask for that explicitly, because some quotes price a single exotic 400A panel that costs more to maintain.

When is 200A enough? For the vast majority of homes under 3,500 sq ft, yes — even with one EV charger. Get the load calc in writing before paying for 400A; upsizing service you will never use is the most expensive kind of peace of mind.

Rewiring cost per square foot

A full copper rewire runs $6–$12 per square foot in 2026. For a 2,000 sq ft home that's $12,000–$24,000 — the wide band is access, not materials. Homes with an open attic, basement, or crawlspace let electricians fish wire fast; slab-on-grade homes with no attic access force drywall cuts in nearly every room, and the patch-and-paint aftermath is on you (budget $2,000–$5,000 for drywall repair separately — most electricians don't include it).

Existing wiring type shifts the price: plain copper replacement sits at the low end, aluminum branch wiring adds ~10% (every splice needs listed AlumiConn or COPALUM connectors), and knob-and-tube adds 20–30% because each run must be fished fresh and the old porcelain left dead in the walls. If your rewire quote doesn't mention AFCI breakers for the living-space circuits, it's missing $400–$800 of code-required hardware — get it itemized.

EV charger install: where the money goes

A Level 2 home charger install breaks into three parts: the charger unit ($500–$800 for a good 40–48A unit), the dedicated circuit ($600–$1,700 depending on the wire run), and the permit ($150–$250). The $1,000–$2,500 total assumes your panel has capacity. The budget-killer is discovering mid-project that it doesn't — a full 100-amp panel turns the job into a $4,000–$6,500 charger-plus-upgrade. Always get the panel-capacity check before the charger quote, and ask your utility about rebates: $300–$1,000 charger rebates are common in 2026 and some utilities discount the electrician's labor too.

Permits and the NEC in plain English

Permits ($100–$500 by scope) are required for panel upgrades, new circuits, rewiring, and EV chargers in most jurisdictions. The permit buys you an inspector's visit — the only independent verification that the work meets the National Electrical Code. The 2020/2023 NEC editions most states enforce now require AFCI protection on nearly all living-space circuits and GFCI in wet locations; when an electrician opens a circuit, code upgrades ride along at $45–$75 per breaker. Unpermitted service work is the single most expensive shortcut in this trade: it can void homeowner's insurance and unravel a home sale at inspection.

DIY vs. hiring a pro

Like-for-like device swaps — a new outlet where one existed, a switch, a light fixture — are legal DIY in most states and save $150–$250 per device. Stop there. Panel work, new circuits, and service upgrades require a licensed electrician and permit nearly everywhere, and the stakes are literal fire: electrical failures cause an estimated 51,000 US home fires yearly. The economical compromise: let the pro do rough-in, panel, and inspection, then install your own designer outlets and plates afterward.

Six money traps

1. The cash panel swap with no permit — saves $300–$500, risks your insurance and your sale.
2. Charger quotes that skip the panel check — the $1,500 quote becomes $5,000 when the panel is full.
3. "$99 per outlet" without the trip fee — always ask the out-the-door total for your device count.
4. Aluminum splices without listed connectors — wire nuts on aluminum are a fire starter; insist on AlumiConn/COPALUM.
5. No load calculation for big additions — hot tubs, EV chargers, and shop subpanels need an NEC Article 220 calc in the quote.
6. Bids 30%+ below the pack — that's the one skipping the permit, the AFCI breakers, or the warranty.

How to read an electrician's quote

A real quote itemizes: materials (panel model, breaker types and count, wire gauge and footage), labor hours and rate, permit fee, and utility coordination. It names the panel brand — avoid Federal Pacific and Zinsco replacements being quoted as "equivalent"; they aren't made anymore for a reason. It states who patches drywall (usually not the electrician). It lists the license number — verify it with your state board in two minutes. Get three quotes; if one is dramatically cheaper, it's missing something the other two included. And never pay more than 30–50% upfront on residential work.

Frequently asked questions

What does a 200-amp panel upgrade include?

A proper 200-amp upgrade includes the new panel cabinet, all circuit breakers, grounding electrode system work, labeling, permit, and utility disconnect/reconnect coordination — $2,000–$4,000 installed in 2026. It does not automatically include a new meter socket ($300–$600 extra) or rewiring old branch circuits, which are separate line items.

How long does a panel upgrade take?

The physical swap takes one day — typically 4–8 hours with the power off. The calendar time is longer: 1–3 weeks for the permit, plus utility scheduling for the disconnect/reconnect, which some utilities only do on certain days. Plan for a full day without power and keep the fridge closed.

Is knob-and-tube wiring dangerous?

Knob-and-tube itself isn't automatically dangerous, but 80-year-old insulation is brittle, it has no ground wire, and it was never designed for modern loads — which is why many insurers refuse coverage or charge more until it's replaced. Replacement runs $6–$12 per sq ft plus a 20–30% premium for fishing wires through finished walls. If you're buying a house with it, budget the rewire into your offer.

How much does it cost to add a dedicated circuit?

A new dedicated 20-amp circuit costs $300–$800 in 2026 depending on distance from the panel and wall access — $500–$1,200 for a 240V appliance circuit (dryer, range, EV charger). Long runs through finished walls, attic work, or trenching to a garage push it higher. If the panel has no free breaker spaces, add a subpanel ($800–$1,500) or a panel upgrade.

Should I upgrade to 400-amp service?

Most homes never need 400 amps — 200 amps covers an EV charger, heat pump, induction range and workshop for a typical family (do the NEC Article 220 load calc first). Consider 400A ($4,500–$8,000) only for very large homes (4,000+ sq ft), two EV chargers plus electric heat, or a detached shop with heavy equipment. Oversizing the service you can't use is pure waste.

What is the difference between AFCI and GFCI?

GFCI (ground-fault) protects people from shock in wet locations — kitchens, baths, garages, outdoors — by tripping when current leaks to ground. AFCI (arc-fault) protects against fires by detecting dangerous arcing in damaged wiring, required on most living-space circuits under current code. Many locations now need dual-function AFCI/GFCI breakers ($45–$75 each). Your electrician, not the internet, decides which your jurisdiction requires.

How do I know if my panel needs replacing?

Replace it if: it's a Federal Pacific or Zinsco brand (documented breaker failure risks); breakers trip constantly under normal loads; you see rust, scorch marks or a burning smell; it's still fuses and your insurer complains; or you're adding an EV charger/heat pump and the load calc says you're over capacity. A healthy modern 200A panel needs no replacement — don't let anyone sell you one.

Can an electrician work without turning off power?

No legitimate electrician works hot on residential service equipment — panel swaps and service work are always done de-energized with utility coordination. Minor device swaps are done with the individual breaker off and verified dead. Anyone who offers to 'work it live to save the permit' is telling you exactly how much your safety is worth to them. Walk away.
