The Different Types of Electrical Contractors

Posted by on May 2, 2023


In the dynamic field of electrical contracting, there are three main types of electrical contractors you’re likely to encounter: Inside Electrical, Outside or Line Contractors, and Integrated Building Systems (IBS) or Voice/Data/Video (VDV) Electrical Contractors. Each type specialises in a unique facet of electrical work, with Inside Contractors focusing on interior electrical systems, Outside Contractors handling high-voltage power transmission and distribution, and IBS or VDV contractors dealing with low-voltage systems like data cabling, security systems, and more. Understanding these distinctions is crucial when it comes to selecting the right contractor for your specific electrical needs.
