Electro technical rating III/7 and work on Low voltage systems

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.
