Plan or renovate electrical installations
Electrical installations include everything a house needs for building services and power supply. From cabling to antenna or telephone systems and modern smart home systems. According to the service life table, power lines last 40 years, lights 20 years and switches or sockets 15 years. If you are renovating or remodeling a house, for example putting in new walls or tearing down walls, you should think about the electrical installations depending on the age of the house.
