External electrical turnkey works refer to the installation, commissioning, and maintenance of electrical systems in outdoor environments. These systems may include street lighting, traffic signals, power distribution networks, and other outdoor electrical installations.

Turnkey projects typically involve a contractor taking on responsibility for the entire project, from design and engineering to installation and commissioning. In the case of external electrical turnkey works, this means that the contractor would be responsible for the design, supply, installation, and commissioning of all the electrical equipment and infrastructure required for the project.

External electrical turnkey works may also involve ongoing maintenance and support, including preventative maintenance, repairs, and replacement of equipment as required. This ensures that the electrical systems continue to function safely and efficiently over the long term.
