A specialty contractor in North Carolina wants to install a 750 kW emergency generator system. The total contract value is $425,000. What license classification is required?
Correct Answer
A) Unlimited Electrical Contractor
Generator systems over 600 kW require an Unlimited Electrical Contractor license regardless of contract value.
Why This Is the Correct Answer
Under North Carolina electrical licensing rules, generator systems exceeding 600 kW require an Unlimited Electrical Contractor license. The 750 kW system in this scenario surpasses the 600 kW threshold, so only an Unlimited license authorizes this work — regardless of the contract dollar value.
Why the Other Options Are Wrong
Option B: Intermediate Electrical Contractor
An Intermediate Electrical Contractor license is insufficient for this project. The Intermediate classification has kW capacity limits that do not extend to systems above 600 kW. The 750 kW generator exceeds the Intermediate license scope.
Option C: Limited Electrical Contractor
A Limited Electrical Contractor license covers smaller-scale electrical work and has both dollar value and capacity restrictions. It cannot authorize a 750 kW system. This is the most restrictive electrical license tier in NC.
Option D: No electrical license required
An electrical license is absolutely required. Emergency generator systems of this size (750 kW) involve significant electrical infrastructure and are squarely within the scope of electrical contractor licensing requirements under NC GS Chapter 87.
Memory Technique
Remember '600 kW = the line for Unlimited.' Any generator over 600 kW needs an Unlimited Electrical Contractor license. Think: '600 is the limit — above that, only Unlimited will do.' The 750 kW system is 150 kW over the limit, requiring the top-tier Unlimited license.
