Which South Carolina electrical license do you need?
South Carolina uses separate commercial and residential contractor paths, not one all-purpose electrician license. For state-level contracting authority, the commercial path licenses the business entity and certifies a qualifying party. The residential path issues an RBE residential electrical contractor license. The state sources reviewed for this guide establish contractor and qualifier credentials rather than a separate statewide journeyman card.
Section 40-11-30 requires a contractor license for mechanical contracting when the total cost of construction for the project is greater than $10,000. Section 40-11-20 defines total cost of construction as costs incurred by the owner, contractors, subcontractors, and other parties for labor, material, equipment, profit, and incidental expenses for the entire project. Do not apply the threshold only to the electrical contract.
The same chapter defines mechanical construction to include electrical components, fixtures, or devices but expressly excludes burglar alarm work. Residential work is a different lane. The Residential Builders Commission says it licenses or registers qualified people for residential work on buildings no more than three floors high and with no more than 16 units in one apartment building. Start by classifying the project, then choose the board. For the broader career ladder, see our electrician license guide.
Commercial EL versus residential RBE
| Path | State authority | Practical trigger | Credential |
|---|---|---|---|
| Commercial / mechanical | Contractor’s Licensing Board | Entire project’s total cost of construction exceeds $10,000 | Entity license with Electrical subclassification and primary qualifying party |
| Residential | Residential Builders Commission | Covered residential buildings and electrical work | RBE residential electrical contractor license |
The Electrical subclassification covers wiring-related material and equipment used to generate, transmit, or use electrical energy below 600 volts. Its listed work includes panels, controls, conductors, conduit, cable, devices, lighting, feeders, and distribution systems. The same subclassification includes the design, installation, and servicing of fire alarm systems. Chapter 11’s mechanical-construction definition expressly excludes burglar alarm work. Fire-alarm scope is therefore not a blanket burglar-alarm authorization.
The split is about legal authority, not just customer type. A residential credential should not be treated as automatic authority for commercial work, and an employee’s experience does not replace the entity license. Read our South Carolina contractor license guide for the broader board structure.
The current mechanical license groups
Electrical sits under the mechanical-contractor side of Chapter 11, so use the mechanical group schedule, not the larger general-contractor limits. Section 40-11-300 requires the total cost of construction for the entire project to determine the license group and forbids dividing work to avoid group requirements. The current per-project caps are:
| Mechanical group | Maximum total project cost | Minimum net worth | Minimum working capital |
|---|---|---|---|
| One | $35,000 | $7,000 | $3,500 |
| Two | $100,000 | $15,000 | $10,000 |
| Three | $200,000 | $30,000 | $20,000 |
| Four | $400,000 | $60,000 | $40,000 |
| Five | Unlimited | $300,000 | $200,000 |
Group One limits bids and jobs to $35,000 per job and requires $7,000 net worth or $3,500 working capital. Group Two limits them to $100,000 and requires $15,000 net worth or $10,000 working capital. Group Three limits them to $200,000 and requires $30,000 net worth or $20,000 working capital. Group Four limits them to $400,000 and requires $60,000 net worth or $40,000 working capital. Group Five allows unlimited bids and jobs and requires $300,000 net worth or $200,000 working capital.
Section 40-11-262 permits a surety bond instead of a financial statement and sets the bond at the net-worth amount for the requested group.
Experience and exam requirements
For the commercial path, section 40-11-230 requires at least 70% on the required technical exam and at least 70% on the South Carolina law exam for general and mechanical contracting. To serve as the entity’s primary qualifying party, the applicant must document full-time employment for at least two years within the previous five years in the requested classification or provide other board-approved experience proof. The same section requires the primary qualifying party to serve in management and be actively involved in supervision and operations.
For the residential path, the Commission’s licensing instructions require applicants to pass the PSI examination and have one year of verifiable experience under a licensed person in the trade. The application materials also call for identity records, work-experience support, a credit report, and other listed documentation.
Do not mix these experience rules. The commercial primary-qualifier standard is two years within the previous five; the residential examination route uses one year of supervised, verifiable trade experience.
Application process
Commercial Electrical subclassification
- Calculate the entire project’s total cost of construction, then choose the mechanical group whose cap covers it.
- Designate a qualifying party and document the primary qualifier’s required experience and management role.
- Pass the technical and South Carolina law examinations.
- Prepare the financial statement required for the selected group, or the permitted surety bond alternative.
- File the entity application, fees, primary qualifying-party information, and supporting documents.
- Wait for issuance before bidding work that requires the license.
Section 40-11-240 requires the entity to submit an approved application, fees, a financial statement or surety bond, and the primary qualifying party’s name and certificate number for each requested classification.
Residential RBE license
- Pass the required PSI examination.
- Document one year of supervised experience.
- Complete the RBE application and listed identity, lawful-presence, credit, and experience records.
- Pay the application and license charges.
- If the licensee does not own at least 51% of the business, address the Commission’s certificate-of-authorization requirement.
The current Commission fee table lists a $135 RBE application fee and a $220 RBE license fee. Exam charges are separate.
Exam waivers are not license transfers
Commercial applicants should treat reciprocity as an exam question, not permission to start contracting. Section 40-11-290 allows a technical-exam exemption when an applicant verifies passing an essentially equivalent exam in another state, but the applicant may still have to pass the South Carolina business, law, and project-management exam and must meet the chapter’s other requirements.
On the residential side, the Commission currently lists technical-exam waiver agreements for the Residential Electrical License with North Carolina and Mississippi and accepts the NASCLA Electrical Exam. The South Carolina Business Management and Law Exam is still required.
A waiver can remove one test. It does not supply the South Carolina entity credential, financial group, experience record, or residential application.
South Carolina electrician license FAQ
Does South Carolina have a statewide journeyman electrician card? The state sources reviewed here establish contractor licenses and qualifying-party certificates, not a separate statewide journeyman card. Local employment, permitting, or competency rules can still apply.
When does the commercial contractor threshold apply? Section 40-11-30 sets the trigger above $10,000, measured from the total cost of construction for the entire project rather than only the electrical contract.
Which commercial classification covers electrical work? The Contractor’s Licensing Board uses the Electrical subclassification under mechanical contracting. Its fire-alarm scope does not erase the statute’s exclusion of burglar alarm work from mechanical construction.
What are the electrical contractor project caps? Mechanical Groups One through Four cap the entire project’s total cost of construction at $35,000, $100,000, $200,000, and $400,000. Group Five is unlimited.
How much experience does the commercial primary qualifying party need? At least two years of full-time employment within the previous five years in the requested classification, or other board-approved experience proof.
How much experience does an RBE applicant need? One year of verifiable experience under a licensed person in the trade.
Does an out-of-state license transfer? No automatic transfer is stated. An equivalent exam may support a technical-exam exemption, but the remaining South Carolina requirements still apply.
