Get MOST of the information to go on this, stays on the CU and know whats inside without poking around.
But why "Maximum Disconnection Time Permitted by BS7671"
It also has "Maximum Zs Permitted by BS7671" what has dropped a bit on AMD3 (cant get used to calling it AMD3 due to being Computer Tech geek type) BS7671:2008 (2015)
Might be better to post things like the BS version when the CU was installed, and another one for the wiring.
So why have "Maximum Disconnection Time Permitted by BS7671" & "Maximum Zs Permitted by BS7671", when its in the book!
