Electricians for Data Center Construction
Licensed electricians with medium voltage, high voltage, and power distribution expertise.
Electricians are the most in-demand trade on every data center construction project. Cortex Construct supplies licensed journeyman and master electricians who specialize in the power distribution systems that define data center infrastructure. From pulling 15kV cable through duct banks to terminating busway and installing PDUs at the rack level, our electricians understand the full scope of data center electrical work and the quality standards it demands.
Demand Drivers
Electrical work represents 30-40% of total data center construction labor hours. With the surge in AI-driven hyperscale builds, demand for data center electricians has outpaced supply, creating significant shortages in markets like Northern Virginia and Dallas-Fort Worth.

Key Data Center Terminology
Specialist terms this trade works with every day. Click any term for a full definition.
Electrical distribution voltage levels between 1kV and 35kV, commonly 15kV and 35kV in data centers. Medium voltage systems carry power from the utility substation to the data center's main switchgear. MV work requires licensed electricians with specific training and certification — these workers are among the most in-demand in data center construction.
A prefabricated electrical distribution system used to deliver power from switchboards to individual racks in data center white space. Busway replaces traditional cable and conduit for the final power distribution run, enabling flexible and scalable power delivery. Busway installation is a specialized skill for data center electricians.
A device that distributes electrical power to IT equipment at the rack level. Floor-mounted PDUs take power from the main distribution and feed individual racks. Rack-mounted PDUs provide the final distribution to servers. PDU installation is a core task for data center electricians, especially during the fit-out phase.
Electrical distribution equipment that controls, protects, and isolates electrical circuits. In data centers, switchgear operates at medium voltage (15-35kV) and low voltage (480V) levels. Main switchgear receives utility and generator power feeds and distributes power through the facility. Installation is performed by electricians with medium-voltage experience.
A device that automatically transfers a power supply from the primary source (utility) to a backup source (generator) when it detects a failure. Data centers use ATSs to ensure uninterrupted power to critical loads. Installation and wiring of ATSs is a key scope for electricians on data center projects.
An electrical panel that distributes power from a PDU to individual circuits serving IT racks. RPPs are located on the data center floor and provide the final level of overcurrent protection before power reaches the IT equipment. Electricians install and wire RPPs during the electrical fit-out phase.
An underground system of conduits encased in concrete that houses electrical cables running from utility substations to the data center. Duct banks protect medium-voltage cables and provide organized pathways for power distribution. Concrete workers and electricians collaborate on duct bank construction.
