The NC SP-PH electrical license lets plumbing, heating and air-conditioning contractors perform the equipment-related electrical work allowed by NCBEEC rule .0807. The SP-PH exam has 40 questions over three hours, with 28 correct answers needed to pass. Prepare with the 2020 NEC and the North Carolina Electrical NASCLA guide.
What work can an SP-PH license holder do?
SP-PH covers electrical work directly related to plumbing, heating or air-conditioning equipment. It does not authorize general building wiring.
Rule .0807 limits this work to systems at 600 volts or less, phase to phase, outside hazardous locations. The protected isolating device and its supply connections must be installed by others. Additional rules govern panel-fed equipment, connection locations and control wiring.
Before bidding a job, identify who will install the supply circuit and disconnect, and confirm that your portion fits the SP-PH scope.

What experience do you need for SP-PH?
You need 3,000 hours of creditable experience, including at least 2,000 primary hours. Qualifying work in plumbing, heating or air conditioning can count. You must also document your role in a lawful NC plumbing, heating or air-conditioning business, as required by rule .0201.
Applicants must be at least 18 and provide two character references. Apply to NCBEEC for approval before scheduling with PSI. The application checklist and forms explain the supporting documents.
Which books are on the SP-PH exam?
Bring these two approved references:
- 2020 National Electrical Code (NFPA 70).
- NASCLA Contractors Guide, North Carolina Electrical, 14th edition.
NFPA 72 is not an SP-PH exam reference. Study NC electrical licensing law and Board rules too. Both are included in the exam handbook.
How to study for the Plumbing/Heating electrical exam
Start with wiring methods, motors, overcurrent protection and business law. These are major sections of the SP-PH exam outline. Also practice grounding, equipment requirements and calculations.
- Work through the JCR manual with the videos. Pause each worked example and solve it before watching the explanation.
- Find the NEC rule behind each answer. For motor questions, identify whether the question asks about conductors, overloads or short-circuit and ground-fault protection before choosing a table.
- Drill the questions you miss. Record the correct reference and the mistake. Rework the problem without the answer in front of you.
- Practice under the exam time limit. Select 40 mixed questions and allow three hours. Review correct answers that took too long, as well as wrong ones.
Common SP-PH license questions
Is SP-PH a plumbing or HVAC license?
It is an electrical contracting classification issued by NCBEEC. It covers the restricted electrical work described above. It does not replace the license needed for your plumbing or heating business.
Do I need SP-PH if I already hold an NC electrical contractor license?
A Limited, Intermediate or Unlimited electrical license covers work within the specialty classifications, subject to the regular license’s own limits. A separate SP-PH license is not required under rule .0801.
Does passing the exam activate my license?
No. After passing, complete the NCBEEC license application before offering electrical contracting services.
