Diversity and max load

[scotsparky]

thats about it but the switchfuse of submain has to me within 3meters of main switch and interlink cable if within 3metres has to carry the maximum submain load.

A power factor of greater than unity is an impossibility!

maybe powerfaqctor is not the correct terminoligy but due to the ballasts and control gear in flouresant fittings a fator of 1.85 has to be addded to show true load.

yeah we know what you meant

splitting hairs

There is a world of difference between a power factor and a correction factor .........

 

[scotsparky]

well done clever boy you spotted a wording mistake ! drop it!

 

[ezzzekiel]

There is a world of difference between a power factor and a correction factor .........

actually theres only the first word, the second are identical

Hey guys just reading though all your replies to my thread....
I will look at the regs as well, thanks for heads up.
The submain cable will be going on a Isolation, as stated in regs over 3 metre it is needing one.

So basically in a nutshell what you fellas are saying is...

1. An isolation switch for submains the Rating of it just needs to cover the Current Carry Capacity (after factors applied etc etc).

2. The Main/RCD switch rating needs to cover the Max demand of the circuits etc etc.

3. I need to mutiply the florescent lighting wattage by 1.8 then do diversity. I take it this is because of the start up current pulled by the module.


Cheers guys,
Big thanks for all your time...
