That doesn't sound ok to me, maybe you should find a way to reduce the Zs by reducing the circuits R2? So your friend is quite happy to have a non-compliant circuit put into service? Strange. ...or increasing csa of cpc. Any equation will refer to neutral as Rn.....so R1+Rn does not determone cpc integrity Regards Antric |

I heard that the HSE are going to "enforce a ban" on the use of 1667 on test forms. If non-compliance occurs, they will enforce this by issuing improvement notices on any installations that show the figure and probably prohibition notices if failure to comply continues.
Anyone else heard of this? |
