update: the customer spoken to the supplier and no joy they have to find out as they dont supply details like that?! FFs how hard is this gonna be!
think im just gonna spec for a 6mm 5c armoured 30m run on a 32C europa is the consumer unit. if it keeps tripping i can refer to the supliers last email they spec the 32a supply.
thinking if i go one bigger on cable size just incase. cannot do no harm.
