Electrical installation should be performed by licensed electricians who have the necessary training and expertise to ensure the installation is done safely and in compliance with local building codes and regulations.

The cost of electrical installation varies depending on the scope of the project, type of equipment and systems being installed, and the labor costs charged by the electrician. It’s best to get a detailed quote from a licensed electrician before proceeding with any electrical installation project.

Some safety precautions to be taken during electrical installation include turning off the power supply, using proper safety equipment, following local building codes and regulations, and hiring a licensed electrician to perform the installation.
