A general contractor subcontracts electrical work on a commercial building. The electrical subcontractor must be licensed as what tier in South Carolina?
Correct Answer
A) Tier III electrical
Commercial electrical work requires a Tier III electrical contractor license regardless of the project value in South Carolina.
Why This Is the Correct Answer
South Carolina's contractor licensing system requires Tier III electrical licensing for all commercial electrical work. This is the highest electrical tier and reflects the complexity, safety requirements, and code knowledge needed for commercial projects. The requirement applies regardless of the project's dollar value.
Why the Other Options Are Wrong
Option B: Tier II electrical
Tier II electrical licensing is appropriate for residential work but is not sufficient for commercial projects. Using a Tier II subcontractor on commercial work would put the general contractor and subcontractor in violation of SC licensing law.
Option C: Any tier depending on project value
Project value does not determine the required electrical tier in South Carolina. The type of construction (commercial vs. residential) determines the tier requirement, not the contract amount.
Option D: Tier I electrical
Tier I is the lowest electrical tier and covers the most limited scope of work. It is not acceptable for commercial electrical subcontracting.
Memory Technique
Commercial = Top Tier. 'Commercial' and 'Tier III' both represent the highest level. Think: 'Big buildings need the best license — Tier III.' Tier I and II stay residential.
