EXTRA LOW VOLTAGE. Extra Low Voltage or ELV is a range of voltages that are considered to be survivable by normal healthy adults should they receive an electric shock. There are two ranges, one for A.C. voltages and the other for D.C. voltages. Both ranges are with respect to zero volts or earth potential and they both begin at zero volts.In electrical engineering, low voltage is a relative term, the definition varying by context. Different definitions are used in electric power transmission and distribution, compared with electronics design. Electrical safety codes define "low voltage" circuits that are exempt from the protection required at higher voltages. These definitions vary by country and specific codes or regulations.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 design, construction, certification, inspection, connection and periodic verification to make sure safety is maintained throughout the life of the installation.
