I
in got a clue
Right bit of a strange one here a customer has brought a 2nd hand walk in sun-shower well i think thats what thay are called (walk in sunbed) so thats 4 panels so its 60 tubes in total im thinking your looking at 32 - 40 amp supply with 6mm to 10mm cable rcd the normal stuff but coming from the sunshower thing there is only a 2.5mm flex so it seems abit odd putting a 2.5mm flex in a 40 amp breaker so am i missing something here as i know full well with 60 tubes are going to pull alot of load on start up but there is no way you can change the 2.5mm flex for abit of 6 - 10mm cable, most of the wiring is done in 1.5mm flex and 2.5mm flex on the sun-shower so im abit confused in what to do any help would be grate
