maximum Zs

Same here, the ONLY reason i'm still with them is that i do a lot of kitchen work for the John Lewis Partnership and they insist on NIC enrollment. If it wasn't for them i'd be off elsewhere!

As far as im concerned the ONLY time 1667 Mx Zs is entered on my EIC is if its a TT install.

The NIC seem to have their own rules, and its not only about this.

Couldn't agree more Wayne, a lot of people seem to think that this is the answer, but not in my book. Also on a new installation I have never failed to meet the max Zs values, if consideration is given at the design stage then there is no reason not to meet it.
