The type b or c isn't to do with 'breaking capacity'. You can get a 32A rcbo in type b or type c. The type b,c (or d) is to do with inrush currents.is installing rcbos type c bad or good type b breaking capacity 30amp
type c breaking capacity 60 amps
i would say not to use type c due to cable failing before breaker
your views please!
is it ok to fit type c or not
The maximum Zs a 6A RCBO can have is 3.09 ohms. However that is at an ambient temperature of 10 degrees centigrade. However if the ambient temperature of that cable exceeds 10 degrees then the Zs will become too high for that RCBO (too high for a type B RCBO as well!).is it ok to fitt type c rcbo 6amp for lighting if zs is below 3.06 ohms
problem is that wholesaler only has 6amp rcbos wylex
I presume you are calcing your 3.06 as the 80% of the value from table 41.3 pg 49 Big Red book???is it ok to fitt type c rcbo 6amp for lighting if zs is below 3.06 ohms
problem is that wholesaler only has 6amp rcbos wylex
