    Ip44 230v zone 1?!

    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

    Ip44 230v zone 1?!

    Water jets as in above a shower but still in zone 1

    Ip44 230v zone 1?!

    I'm sure I read zone 1 is ipx5 or did I imagine it :/ The ecd bit on the box is a joke ?

    Ip44 230v zone 1?!

    So the light i have states that's its ip44 but can be used in zone 1? I thought zone 1 was ipx5 and above

    Drilling holes?

    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...

    Drilling holes?

    Due to de rating factors?

    Drilling holes?

    Thats how i feel but is it allowed

    Drilling holes?

    I thought but I'm not sure you could drill rafters though?

    Drilling holes?

    Yes Needs to be boarded

    Drilling holes?

    Can these be drilled? The diagonal beams going up to the roof that is?

    Zs and circuit length

    ? 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...?

    Zs and circuit length

    But what would count as an overly long circuit? 100m? 150m?

    Zs and circuit length

    So if its long best bet is to just use a smaller mcb go from 6amp to a 4amp or a c type to a b type or use a bigger cable

    Zs and circuit length

    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...

    Zs and circuit length

    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?

    Zs and circuit length

    Cheers man:) So if the circuit after all that doesn't meet zs does it comply if put on an rcd or rcbo

    Zs and circuit length

    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?
  18. dokkan1080

    Zs and circuit length

    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
  19. dokkan1080

    Zs and circuit length

    How would you do it I guess because when know the resistance of the cable
  20. dokkan1080

    Zs and circuit length

    if you have the ze and know the length of a circuit can you calculate the zs ? Ze : 0.24 Circuit length : 100m 1.5mm cable twin
