Hi
I'm looking at Table 7.1(i) in the On Site Guide. Max length of cable runs.
In some cases where there is no RCD protection the length is given as a number with a zs suffix. eg 47zs
The zs suffix means "limitted by Zs" the final circuit line-earth loop impedence.
In these cases is the number part the actual max length? For example 47zs = 47 meters?
Thanks
