What do you write down for the zs in a TT system

 

[trev]

Do you mean the max allowed? There's a thread on this in I&T from yesterday mate

 

[linfield-sparky]

Max allowed yes

 

[Octopus]

I write down the max for the MCB, yes I know it could be 1667 but simply won't rely on RCD's

10 to the power of 24*. ;-)


its 1667 ohms really.


* im hoping someone with better computer skills converts that to its proper notation.

 

[Stroppy]

10^24 is the usual way of denoting powers

or 10[SUP]24[/SUP] if you're a smart-ar$e!

on a 30MA rcd yes, what about a 100 MA though, or a 300 MA :earmuffs:

Smart arse :rofl:


BTW is the answer 10,000,000,000,000,000,000,000,000? I think it is?

Paul you must have a 3 foot wide calculator to do that sum
I get stumped just counting how many noughts you have posted

No mate, I just know a short cut to working out 10 to the power of 24 off the top of my head if I've remembered it correctly from my school days :roll:

 

[telectrix]

now who's the samartarse? :yesnod:

 

[Stroppy]

Instead of clicking 'quick reply', click 'go advanced', then you can use the X[SUP]2[/SUP] button which is on the third row of buttons to make the 2 superscript.

 

[Paul.M]

24[SUP]10[/SUP] = 10,000,000,000,000,000,000,000,000 I think???

With any sum to the power of ten (eg 5[SUP]10 =[/SUP] 5,00,000) all you have to do is add a 0 t the power of the number time-sing the actual number. If its to the power of 24 then add 24 0's after the number, if it is 4[SUP]10[/SUP] just add 10 lots of 0's after the 4 and so on. But I may be wrong on that so wait until someone confirms it lol.

 

[derek]

I could be wrong but I think it is 10[SUP]24[/SUP] that equals 10 000 000 000 000 000 000 000 000. i.e. 10 multiplied by itself 24 times.

Edit:
Sorry just reread the thread to realise that Paul made a mistake in his last post but his others were correct.
