How do I know if I need a 200A or 400A upgrade?
A load review is the starting point. The answer depends on current loads, future equipment, service requirements, and property goals.

What Happens During a 200A or 400A Electrical Service Upgrade?
A service upgrade typically involves reviewing existing loads, planning future loads, coordinating permits and inspections, utility coordination where needed, and replacing or upgrading service equipment.
Short Answer
A 200A or 400A service upgrade is not just a larger panel. It is a planning process around current electrical demand, future equipment, utility requirements, inspections, equipment layout, and the safest way to support the property’s needs.
The right scope depends on what the customer is adding now and what they may add later.
Why Service Upgrades Happen
Service upgrades are often considered when a property is adding larger electrical loads or needs more usable capacity. Common triggers include EV chargers, battery systems, backup generators, additions or ADUs where applicable, commercial equipment, full panels, older equipment, and future capacity planning.
For commercial spaces, upgrades may also be tied to tenant improvements, dedicated circuits, equipment feeds, lighting changes, or higher-load business operations.
Load Review and Planning
Load review helps determine whether 200A, 400A, or a different scope makes sense. Bigger is not automatically better. The decision should reflect the real loads, future goals, service requirements, equipment location, and how the property will be used.
Permits and Inspections
Service upgrades commonly involve permits and inspections. Requirements and timing can vary by scope and jurisdiction, so the electrical plan should leave room for review, coordination, and field conditions.
Utility Coordination
Utility coordination means working around utility-side requirements that may affect the meter, service conductors, shutdowns, reconnection, or service equipment. Not every project has the same utility involvement, but service upgrades often need this step reviewed early.
200A vs 400A
A 200A upgrade may be enough for many properties, while 400A may be considered for larger homes, commercial spaces, multiple high-demand loads, or future power needs. The right decision should be based on load planning, not guesswork.
What Customers Should Prepare
Helpful starting information includes photos of the existing panel and meter area, a list of planned equipment, future electrical goals, preferred equipment locations, and any timeline constraints. This helps BNV Electric understand whether the project is mainly a panel upgrade, a service upgrade, or part of a larger electrical scope.

FAQs
Does an EV charger require a service upgrade?
Not always. Some panels can support a charger, while others need panel work, load management, or a larger upgrade.
Does solar or battery backup affect service upgrade planning?
Yes, it can. Solar and battery equipment should be considered with panel capacity, critical loads, equipment location, and future backup-power goals.
Does the utility need to be involved?
Utility coordination may be needed for service upgrades, meter work, shutdowns, reconnection, or utility-side requirements.
Can BNV Electric handle panel/service upgrades for homes and businesses?
Yes. BNV Electric plans panel and service upgrade electrical work for local homes, businesses, and properties.
