Dear all. Do anyone know where I can find the regulations regarding what voltage an ETR III/7 certified electrician rating can work on, on ships. From what I assume, they can work on low voltage system under 1000V..

Hi John, yes the ETR III/7 are certified to work on low voltage facilities under 1000V.

This is the descripton for electricians as it is stated in the introduction to the section.

Here is the Norwegian regulation: [https://lovdata.no/dokument/SF...](https://lovdata.no/dokument/SF/forskrift/2011-12-22-1523/KAPITTEL_5#KAPITTEL_5)

See § 45.
