1LV System Installation
LV Systems
In electrical engineering low voltage is a relative term, the definition varying by context. Different definitions are used in electric power transmission and distribution, and electrical safety codes define "low voltage" circuits that are exempt from the protection required at higher voltages.
2Extra Low Voltage Systems Design and Installation
ELV Systems
Electrical installations at low and extra low voltages need to be designed and installed in a way that ensures they will be safe to use. There are processes surrounding the choice of design, construction, certification, inspection, connection and periodic verification to make sure safety is maintained throughout the life of the installation.
