Hi
i have a TT install that needs an RCD installed between the supply amd the metal consumer unit contining RCDs and RCBOs.
ZS is pretty good @ 40ohms so was looking at 300mA. Looking at S type 4 pole RCDs from CEF online and the time delays settings to start at .2! The maximum allowable for a TT is .2 so cutting a bit fine in my book. Is this the norm for all S type RCDs, starting at .2?
thanks
john
