What is an Electrical Panel Upgrade?

An electrical panel upgrade is a process that involves replacing an outdated or insufficient electrical panel with a new, modern one that meets current safety standards and can handle the increased electrical demands of a home. The main reasons for upgrading an electrical panel include:

  • Insufficient capacity for modern electrical needs
  • Outdated or unsafe panel (e.g., Federal Pacific, Zinsco, or Challenger panels)
  • Adding new appliances or electrical equipment
  • Adding Heat Pumps or Heat Pump Water Heaters
  • Preparing for home renovations or additions

However, when people say “electrical panel upgrade,” they often mean an electrical service upgrade, which requires more work than just replacing an electrical panel.

A service upgrade involves replacing the meter socket, main service cable, and grounding system in addition to the panel. Low prices of $1,500 to $3,000 advertised online for electrical panel upgrade cost, often only cover the panel replacement and not the full scope of work required for a complete electrical service upgrade.

Factors Influencing Panel Upgrade Prices

Several factors can impact the cost of an electrical panel upgrade, including:

What's Included in an Electrical Service Upgrade?

A complete electrical service upgrade typically includes:

  • Installation of a new 200 AMP panel & meter with bypass combo
  • Replacement of the main service cable from the meter to the panel
  • Grounding to cold water pipe or ground rod
  • Installation of a whole house surge protector
  • Installation of an outdoor service GFCI receptacle (if required by local code)
  • Other code compliance work
  • All permitting, inspection, and associated fees

Code Requirements for Panel Upgrades in 2024

As of 2024, code requirements for electrical panel upgrades include:

  • Installation of a whole house surge protector to protect sensitive electronic equipment from voltage spikes
  • Proper grounding to cold water pipe or ground rod to ensure safety and reduce the risk of electrical shock
  • Installation of AFCI (Arc Fault Circuit Interrupter) breakers in bedrooms and living areas to protect against electrical fires
  • Installation of GFCI (Ground Fault Circuit Interrupter) protection in kitchens, bathrooms, garages, and outdoor areas to prevent shock hazards
  • Other items specific to local codes and regulations, such as minimum wire sizes, conduit requirements, and working clearances around the panel

Determining Current Panel Size

To determine the size of your current electrical panel, locate the main breaker, which is usually the largest breaker in the panel. The amperage rating of the main breaker indicates the panel size. Common residential panel sizes include

Upgrading Electrical Panel from 100 to 200 Amps

The cost of upgrading from a 100-amp to a 200-amp panel can vary depending on several factors, such as the age and condition of your home’s existing electrical system, the location of your panel and permitting and inspection fees. On average, homeowners can expect to pay between $4,000 and $6,500 for a complete 100 to 200-amp panel upgrade.

This cost typically includes:

  • A new 200-amp meter socket and main breaker
  • A new 200-amp panel with circuit breakers
  • New wiring and conduit as needed
  • Grounding and bonding to meet current codes
  • Removal and disposal of the old 100-amp panel and equipment
  • Permitting and inspection fees
  • Labor costs for a licensed electrician

It’s important to note that the cost may be higher if your home requires additional work, such as upgrading the meter base, replacing the main service cable, or bringing other aspects of your electrical system up to current codes. In some cases, the utility company may need to upgrade their equipment, which can add to the overall cost and timeline of the project.

Power Outage Duration During a Panel Upgrade

During an electrical panel upgrade, power is usually out for 5 to 8 hours on the day of installation. In some cases, the electrician may be able to work around critical circuits to minimize disruption, but it is best to plan for a full day without power. If you have critical electrical needs, such as medical equipment or work-from-home requirements, discuss these with your electrician in advance so they can help you plan accordingly.

Subpanel Installation as an Alternative

Installing a subpanel can be an alternative to a full electrical panel upgrade in certain situations. A subpanel is a smaller electrical panel that is fed by the main panel and can be used to expand the number of circuits in a specific area of the home, such as a garage, workshop, or addition.

The cost of a subpanel installation ranges from $1,400 to $3,500, including permitting and labor for a 50-100A subpanel. This can be a more cost-effective solution than a full panel upgrade if:

  • The main panel has sufficient capacity and is in good condition
  • The home only needs additional circuits in a specific area
  • The home has space for a subpanel in the desired location

Subpanel Benefits and Reasons for Needing One

Subpanels offer several benefits and can be a good solution in various situations, such as:

However, it’s important to note that a subpanel may not be the best solution if your main panel is outdated, in poor condition, or undersized for your home’s electrical needs. In these cases, a full electrical panel upgrade may be necessary to ensure the safety and reliability of your home’s electrical system.

200A to 400A Upgrades

Upgrading from a 200A to a 400A electrical service is a complex and expensive process, particularly for residential homes. The cost associated with such an upgrade can add $10,000 to $15,000 to the project at a minimum. This type of upgrade is more common in commercial settings and is rare in residential properties due to the cost and complexity involved.

To complete a 200A to 400A upgrade, the following steps are required:

  1. Engineering and design work to ensure the new service meets all applicable codes and standards
  2. Separate applications and approvals from the utility company, which may include a load calculation and justification for the increased service size
  3. Significant changes to the utility company’s transformers, lines, and distribution infrastructure to accommodate the higher amperage

The utility company will require the customer to justify the need for the increased capacity and may ask them to pay for some or all of the costs associated with the necessary infrastructure upgrades. In residential settings, 400A services are usually installed in ultra-large homes at the time of new construction, where the electrical demands are high enough to warrant the additional capacity.

Examples of homes that may require a 400A service include:

While it is possible to upgrade existing houses to 400A, it is rare and very expensive. The process involves replacing the meter socket, main service cable, and panel, as well as upgrading the grounding system and potentially making changes to the home’s wiring to accommodate the increased capacity. In most cases, homeowners will need to work with an electrical engineer and the utility company to develop a plan and obtain the necessary approvals. In addition, most 400A (or similarly sized) equipment has lead times exceeding 20 to 40 weeks.
