Electrical Service Upgrades For Homes In Loveland 100 Amp 200 Amp And 400 Amp
Increase Your Home’s Electrical Capacity With A Properly Sized Service Upgrade
Most homes today use far more electricity than they were originally designed to support. Electrical systems that once handled basic appliances and lighting are now expected to power EV chargers, larger HVAC systems, electric appliances, workshops, and expanded living spaces.
When the incoming electrical service cannot keep up, the entire system begins showing signs of strain. Breakers may trip more often, lights may react when large equipment starts, and adding new electrical equipment can become difficult.
An electrical service upgrade increases the amount of power your home receives from the utility. Unlike an electrical panel upgrade, which improves distribution inside the home, a service upgrade increases the supply feeding the entire electrical system.
At RCI Electric, we evaluate your home’s complete electrical setup and determine whether a service upgrade is the right solution. We help homeowners throughout Loveland and Northern Colorado improve system capacity, reliability, and long-term performance.
What An Electrical Service Upgrade Actually Changes
A service upgrade can:
- Increase the total electrical capacity entering your home
- Allow your electrical system to support higher demand
- Provide additional capacity for EV chargers, HVAC systems, and workshops
- Reduce strain across the electrical system
- Improve performance when multiple loads operate at the same time
A service upgrade is not simply about adding more circuits. It increases the amount of power available to the entire home.
Common Electrical Service Sizes
100 Amp Service
Many older homes still operate with 100 amp electrical service. While this was often sufficient when these homes were built, modern electrical demand has increased significantly.
A 100 amp service may become limited when adding:
- EV chargers
- Electric appliances
- HVAC upgrades
- Home additions
- Workshop equipment
Many homeowners choose to upgrade when their electrical needs exceed what the original service was designed to provide.
200 Amp Service
A 200 amp electrical service is common in many modern homes and supports most standard electrical demands.
It can typically support:
- General household appliances
- HVAC systems
- Modern electronics
- Many EV charging setups
However, larger homes and higher-demand properties may eventually require additional capacity.
400 Amp Service
A 400 amp electrical service is designed for homes with significant electrical demand.
It may be recommended for:
- Larger homes
- Multiple HVAC systems
- Multiple EV chargers
- Workshops
- Fully electric homes
- Properties with extensive electrical equipment
A larger service is not about adding unnecessary capacity. It is about ensuring the electrical system can operate without constantly reaching its limits.
Types Of 400 Amp Service Setups
Not every 400 amp service installation is configured the same way. The correct setup depends on the home, electrical demand, and utility requirements.
Meter Main Or Pass Through Setup
This configuration allows power to enter through a main disconnect or meter main combination before feeding one or more distribution panels.
This setup is commonly used for residential applications where larger electrical capacity is needed.
CT Cabinet Current Transformer Setup
A CT cabinet setup uses current transformers for utility measurement instead of standard direct metering.
This is commonly used for larger homes or more complex electrical systems requiring higher capacity.
Dual 200 Amp Panels
Some homes use a 400 amp service that feeds two separate 200 amp electrical panels.
This allows electrical loads to be distributed across multiple panels and is common in larger homes with multiple systems.
When The Incoming Power Is Not Enough
Some electrical issues are not caused by the panel itself. They happen because the amount of power entering the home is too limited.
Common signs include:
- Breakers tripping even when circuits are properly distributed
- Lights dimming throughout the home when equipment starts
- Electrical issues continuing after a panel upgrade
- The home being unable to support EV chargers or additional equipment
- Electrical demand exceeding the original service size
If the limitation is with incoming power, a service upgrade may be needed instead of only changing the panel. Learn more about electrical panel upgrades.
How Electrical Service Limitations Show Up In Real Use
Whole Home Performance Issues Under Load
When multiple electrical systems run at the same time, an undersized service may struggle to keep up.
New Equipment Creates Electrical Problems
Adding EV chargers, HVAC equipment, or major appliances can expose limitations in the existing service.

Panel Upgrades Do Not Fully Solve The Problem
If the panel has already been upgraded but electrical issues continue, the incoming service may still be undersized.
Voltage Drop Throughout The Home
Voltage fluctuations, dimming lights, or performance issues when large equipment starts can indicate the electrical service is struggling under load.
Increasing Electrical Demand In Modern Homes
Electrical demand has changed significantly over the years. Many homes now require capacity for:
- EV chargers and multiple charging stations
- Larger HVAC systems
- Electric water heaters, ranges, and appliances
- Workshops and garages
- Additional living spaces
- Detached structures
Across Northern Colorado, many homes have expanded their electrical usage without upgrading the incoming service that supports the system.
Utility Coordination During A Service Upgrade
Electrical service upgrades require coordination with the local utility provider.
The process may include:
- Disconnecting and reconnecting electrical service
- Updating service equipment
- Replacing or upgrading meter equipment
- Completing required inspections
- Coordinating approvals before reconnecting power
RCI Electric manages the electrical side of the process to help ensure the upgrade is completed safely and correctly.
What We Evaluate Before Recommending A Service Upgrade
We evaluate the entire electrical system before recommending additional capacity.
Our evaluation includes:
- Current service size and condition
- Total electrical load
- Panel configuration
- Conductor sizing and condition
- Grounding and bonding
- Future electrical plans
This helps determine whether a service upgrade is actually necessary or if another solution would better address the issue.
Load Calculations And Proper System Sizing
Electrical service upgrades should be based on actual demand, not assumptions.
Through load calculations, we determine:
- Total electrical demand
- Required service size
- Available capacity for future expansion
The goal is to create a system that is properly sized for current use and future needs. Learn more about load calculations and electrical system planning.
Electrical Factors That Affect Service Capacity
Several components affect how well your electrical system performs, including:
- Load distribution across circuits
- Voltage drop from undersized conductors
- Condition of service entrance wiring
- Grounding and bonding performance
- Relationship between service size and panel capacity
A properly designed electrical system depends on all of these components working together.
Service Upgrade Vs Panel Upgrade
Service upgrades and panel upgrades solve different problems.
Electrical Service Upgrade
A service upgrade:
- Increases the amount of power entering the home
- Improves available electrical capacity
- Supports larger electrical demands
Electrical Panel Upgrade
A panel upgrade:
- Improves how power is distributed inside the home
- Allows better circuit organization
- May increase available breaker space
Many homes require both solutions depending on their electrical needs. These components work together as part of a complete power distribution system. Learn more about electrical panel upgrades and power distribution.

When A Service Upgrade Becomes Necessary
A service upgrade may be needed when:
- The electrical system cannot support additional equipment
- Demand exceeds the current service size
- The home experiences performance issues under load
- Major electrical additions are planned
When incoming electrical capacity becomes the limiting factor, increasing the service size is often the long-term solution.
