Can you use a 20 amp rotary isolator for isolation of a hot tube??? The run is about 10 metres in 6mm SWA into a 20 amp isolator then straight into a 30ma RCD class 2 inclosure using a b type 20 amp mcb, there is also a B6 type mcb for a lighting circuit which is going into zone 1 which is not low voltage!!!
Im asking coz apparently even thou im 17th edition and have told him you cant have a light in a zone 1 and im pretty sure it needs to be a 45amp Rotary isolator and not a 20amp, the guy he has asked fair play has been a spark for years but does all industrial stuff and doesnt have 17th and is asking mates about how to do it!!! Me on the other hand has, but doesnt listen to me coz he trusts his mates judgement first!!!
Family are a pain in the ---!!!
Someone tell me im right please!!!
