A Class C-20 warm air heating contractor wants to install both heating equipment and the electrical connections. What additional licensing requirement must be met?
Correct Answer
C) Obtain a Class C-10 electrical license
Electrical work requires a Class C-10 license. The C-20 license does not authorize electrical connections beyond low-voltage controls.
Why This Is the Correct Answer
A C-20 license authorizes warm air heating, ventilating, and air conditioning work, but it does not include electrical wiring beyond low-voltage controls. Any line-voltage electrical connections require a Class C-10 Electrical Contractor license. This is a hard scope boundary enforced by CSLB.
Why the Other Options Are Wrong
Option A: File for a specialty license exemption
Filing for a specialty license exemption is not a valid mechanism under CSLB rules for performing work outside your licensed classification. No such exemption process exists for electrical work.
Option B: Complete additional electrical training hours
Completing additional electrical training hours does not grant authority to perform electrical work. Licensing, not training alone, is required. The CSLB evaluates qualifications through examination, not informal training hours.
Option D: Partner with a licensed electrician
Partnering with a licensed electrician is a common practical solution, but it is not the licensing requirement described. The question asks what the contractor themselves must do if they want to perform the electrical work personally.
Memory Technique
C-20 = Cold and Hot air. C-10 = Current (electricity). When a job needs both, you need both licenses. The number 10 literally looks like a wire and plug.
