Who We Are

National Cable Splicing Certification Board (NCSCB) Inc. is a not-for-profit organization devoted to the development and administration of a Personnel Certification program for Medium Voltage Cable Splicers. NCSCB was created in 2004 with representatives from utilities, contractors, manufacturers, organizations, cable splicers and others who are interested in affirming the KSA (Knowledge, Skills and Abilities) of workers who splice and terminate medium voltage electrical power cables.

Currently, the certification consists of a written examination that focuses on common core knowledge of medium voltage cable, accessories and safety related topics. A performance or practical examination is also administered that requires the candidate to demonstrate core knowledge, skills and abilities common for Medium Voltage Cable Splicers working with shielded electrical power cables.

We presently offer three categories of splicing certifications:

  • Written
  • Manufactured kits (splices and terminations)
  • Hand-applied taping


Pricing can be found on our FAQ Page
NOTE: NCSCB has been established for certification purposes only and therefore does not offer any preparatory training. However; a list of suggested training documents can be found on the Preparation Page.

Why Certification?

Many experts agree that the vast majority of Medium Voltage cable and accessory related failures are due to poor workmanship. A properly administered certification program can help assure utilities, contractors, customers and the public that properly trained and equipped personnel will be handling and terminating the cables and components that make up a well-engineered medium voltage distribution system. Certified personnel splicing and terminating medium voltage cables can also help to reduce SAIFI (System Average Interruption Frequency Index) used by most utilities as an indicator of system interruptions.

Frequently Asked Questions

What is Certification in Medium Voltage Cable Splicing?

The NCSCB Inc. has developed a comprehensive program that allows an individual to demonstrate his or her knowledge, skills, and abilities in splicing and terminating shielded electrical power cable. By the passing of both a written and a performance (practical) exam, competency of splicing will be recognized by the issuance of a certification card in the specialties that were examined.

Why offer certification in Medium Voltage Cable Splicing?

Much has been written on the competency and the workmanship of individuals performing medium voltage cable splicing work. Industry supported programs that are developed and administered on a National basis, will go far in establishing levels of competency that meets the needs of industry and the public for safe and reliable delivery of electrical power. Certification will enable us to formally recognize those individuals that have successfully demonstrated an understanding of the knowledge, skills, and abilities of cable splicing.

Who Should Obtain Certification?

All individuals that splice or terminate medium voltage solid dielectric shielded power cables through 35kV. Certifications in PILC and higher voltage cables will be available soon.
The intended candidate for the NCSCB Inc. electrical power cable examinations works primarily as a construction/industrial or specialty electrician/lineman for an electrical utility or an electrical contractor (EC) engaged in network systems, underground distribution construction and maintenance, or commercial/industrial installations.

Prerequisites to Certification

At least two (2) years work in the medium voltage shielded power cable industry. This can be, but not limited to, employment by an electric utility, contractor, engineering, or others in the industry.
The certification is good for a period of seven (7) years from the date of issuance, provided the Splicer maintains his or her NCSCB Inc. membership in good standing.
