Power Systems Built for Expanding Demands
Service Upgrades in Jonesboro for properties with insufficient electrical capacity or planned expansions
Chamberlain Electric LLC provides electrical service upgrades in Jonesboro when existing power capacity no longer supports household or business demands. Older homes typically operate on 100-amp or 150-amp service panels, but modern electrical loads from heat pumps, electric vehicle chargers, workshops, or kitchen renovations often require 200-amp or larger capacity. Service upgrades replace the entire connection from the utility meter through the main panel, expanding what your electrical system can safely deliver.
The process involves coordinating with the utility provider to disconnect power temporarily, installing a new meter base and service entrance cable, mounting a larger main breaker panel, and redistributing circuits to balance loads properly. Code-compliant installations ensure that grounding systems, overcurrent protection, and conductor sizing meet current National Electrical Code standards, which have evolved significantly since many existing services were originally installed. Properties adding significant square footage, converting to all-electric systems, or installing equipment with high startup currents typically trigger the need for service upgrades.
Schedule a property evaluation to determine if your current electrical capacity meets your planned equipment additions.
Service upgrades require utility coordination, proper permitting, and inspection approval before power restoration. The work includes verifying that service entrance conductors are sized correctly for the new amperage rating, confirming that grounding electrode systems meet code requirements, and ensuring that the main panel has adequate space for future circuit additions. In residential projects, this often means moving from fuse boxes or undersized breaker panels to modern load centers with combination AFCI/GFCI breakers for enhanced protection.
After Chamberlain Electric LLC completes the upgrade, you'll notice that multiple high-draw appliances can operate simultaneously without tripping breakers, voltage drops that previously dimmed lights when equipment started no longer occur, and your electrical system has documented capacity for future renovations. The work eliminates the hazard of overloaded service conductors, which degrade insulation over time and create fire risks in undersized systems.
Service upgrades include the meter base, service entrance cables, main disconnect, and panel installation, but typically do not include interior circuit rewiring unless existing branch circuits are damaged or non-compliant. Properties with aluminum wiring, ungrounded outlets, or outdated subpanels may require additional work beyond the service entrance upgrade itself.
Questions Before Expanding Electrical Capacity
Service upgrades in Jonesboro address the gap between what older electrical systems were designed to handle and what modern equipment demands.
How do I know if my property needs a service upgrade?
If your main breaker trips frequently when running multiple appliances, if you're adding equipment like heat pumps or EV chargers that exceed your panel's available capacity, or if your current service is 100 amps or less and you're planning renovations, an upgrade is typically necessary to support the increased load safely.
What does the installation process involve?
The utility company disconnects power at the transformer, existing meter and service entrance equipment are removed, new components rated for higher amperage are installed with properly sized conductors, the system is inspected and approved, and the utility reconnects power once all work passes final inspection.
How long does a service upgrade take?
Most residential service upgrades require four to six hours of on-site work, though complex installations with challenging service entrance routing or required panel relocations may extend the timeline, and utility coordination for disconnect and reconnect adds scheduling considerations.
Will upgrading to 200-amp service increase my electric bill?
The service upgrade itself does not increase consumption; you pay only for the electricity you use, but the larger capacity allows you to operate more equipment simultaneously without overloading the system or creating safety hazards.
What happens to existing circuits during the upgrade?
Existing branch circuits are transferred to the new panel and redistributed across available spaces to balance loads properly, though circuits with outdated wiring methods or insufficient grounding may require replacement to meet current code standards.
