I have a question,

When testing a circuit protected by an RCBO, lets say a type B, in the max permissible column do you put the value from the Regs for the breaker type or 1666 Ohms?
Rang the NIC Tech line and NAPIT's and they both say different.

It's just that if you put the value from the Regs and there is a high Zs it looks odd on the paperwork.

Cheers

if its a TT system then i put <1667.

If not, then its the Max for given MCB/RCBO in the regs, not the OSG.
