Generator installation involves more than dropping a unit in your yard. Here's how Overwatch Electric approaches every job.
We visit your property, review your electrical panel, and calculate which circuits or square footage you need covered. This step determines the right generator size for your situation.
Our electricians install the transfer switch and make all necessary panel connections. This is the most critical part of the job and must meet South Carolina electrical code.
We wire the generator to the transfer switch, complete proper grounding, and route any conduit needed to keep the installation clean and protected.
Before we pack up, we run a full operational test and walk you through how to operate the system, including what to expect during an automatic switchover if you have a standby unit.
Find clear answers about service options, scheduling, preparation, and what to expect before you request an estimate.
Q1
Yes. Most permanent standby generator installations require an electrical permit in Columbia and surrounding jurisdictions. Overwatch Electric handles the permitting coordination so the installation meets local code requirements.
Q2
A transfer switch disconnects your home or business from the utility grid before the generator powers your circuits. Without one, backfeed can injure utility workers and damage your equipment. It's a required part of any proper generator installation.
Q3
In most cases, yes. We assess your current panel capacity during the site visit. Some older panels may need an upgrade before a generator can be safely integrated, and we'll tell you upfront if that's the case.
Q4
Size depends on what you want to power. We run a load calculation based on your critical circuits or full-home needs. Choosing too small a unit causes overloads; choosing too large costs more than necessary. We help you find the right fit.
Q5
We handle the electrical work for both types. Standby units require a permanent transfer switch and dedicated wiring. Portable generators can use a manual transfer switch or interlock kit. We'll recommend the right setup based on your usage and budget.
Q6
Most residential standby generator installations take one day for the electrical work, assuming the generator unit is already on-site and no major panel work is needed. More complex commercial jobs may take longer, and we'll give you a realistic timeline before starting.
Q7
Overwatch Electric installs generators throughout Columbia, Lexington, Irmo, Pontiac, Chapin, and West Columbia, SC. If you're unsure whether we cover your location, call us and we'll confirm.
Q8
We test the full system before leaving and walk you through operation. If you have a standby unit with automatic transfer, we verify the switchover works correctly. Any follow-up electrical questions after the install, you can reach us directly.
