The zones are from the finished floor level what if you shower try is not on the finished floor level what if its raised up 6inches would you measure the zone from the tray or the bathroom floor
That was the plan, but now its all changed :/
I'm getting the idea that drilling them is not a good idea, that and if the ring goes up and over the roof it needs to be de rated if its in the Insulation...
?
So of you was tncs type b 6 amp you are pretty much good up to 90 meter.
But if you was to drop to a 4 amp type b mcb you can go longer but as a rule you know 90 meters will comply at 6 amps
So its best to design a circuit to the breaker size and not your loads...?
My dude you are a legend real, the above is like a college lesson.
So what if its out of reach like a light and a class 2 fitting then its not high risk...
But a metal fitting light switch is...
The fact you can go lower than 6 amp mcb is pretty cool that means you can use longer circuit...
So if your voltage drop was complaint but your zs was not using a rcd or rcbo would make the circuit comply?
But I'm guessing that would be bad design but still complaint....:/? Of so why would it be done like that would it be down to cost or lack of a better option?
So if my circuit was 100 meter it would be :
1.5/1 mm cable is 30.20 /1000= 0.0302
0.0302x100= 3.02 + ze wpuld equal zs but the zs should be lower than that due to parallel pathes to earth?
Will the zs be lower or higher or does it depend?
So for example how would I work out the calculated zs of 1.5/1 twin at 100m with a ze of 0.24
Find 1.5mm/1mm in that table times it by 100 then add the ze to it
