We keep the process straightforward so you know what to expect from first contact through completed installation.
We evaluate your current panel, discuss your power needs, and identify the right upgrade path for your property in Columbia or the surrounding area.
Before any work begins, we walk you through what the upgrade involves, including materials, timeline, and any utility coordination that may be needed.
Our licensed electricians complete the panel upgrade safely and cleanly, following all applicable South Carolina electrical codes throughout the installation.
Once installation is complete, we test the new panel, verify everything is functioning correctly, and answer any questions you have before we leave.
Find clear answers about service options, scheduling, preparation, and what to expect before you request an estimate.
Q1
Common indicators include frequently tripping breakers, flickering lights, a panel that feels warm to the touch, or a fuse box that hasn't been updated in decades. If you're adding large appliances or an EV charger, your current panel may also need increased capacity.
Q2
Most modern homes operate well with a 200-amp service panel. Older properties may still have 60 or 100-amp panels, which often fall short of today's electrical demands. The right size depends on your specific usage and future plans.
Q3
Yes, someone should be present during the upgrade since power to your property will be temporarily shut off during the installation process. We work efficiently to minimize the time your power is off.
Q4
Yes, electrical panel upgrades typically require a permit in South Carolina. Overwatch Electric handles the permit process and ensures all work is inspected and code-compliant before the job is considered complete.
Q5
Absolutely. If your current panel lacks the capacity for a Level 2 EV charger, upgrading the panel first is often a necessary step. Overwatch Electric installs both panel upgrades and EV chargers, so we can coordinate both services.
Q6
Most residential panel upgrades are completed within a single day. Commercial or more complex jobs may take longer depending on the scope. We'll give you a realistic timeline during the assessment phase.
Q7
Yes. In addition to Columbia, we serve Lexington, Irmo, West Columbia, Chapin, and Pontiac. If you're unsure whether we cover your area, give us a call and we'll confirm quickly.
Q8
If our electricians identify other concerns during the upgrade — such as outdated wiring or safety hazards — we'll communicate that clearly and discuss your options before proceeding with any additional work.
