Spot on mate, your first answer was a good one and I had to pass it on Richard as I wasn't sure! Plenty of time to have another go mate

 

[Richard Burns]

It was a good answer, it just needs more thought and more basic application of does it comply with "the rules".

 

[pennychew]

That's two more correct entries and I learned a new formula from one of them (thanks Simon!) I'll let this run for another couple of weeks but get your entries in lads... So far I can think of at least Doody, happysteve, Northstar, bigash and a couple of others who I think could answer this one with ease! (Electrochem could do this in his sleep but he would need to give me board and lodgings for two weeks so i can deliver it in person! :smile5

 

[Richard Burns]

Roll up, roll up, get your free clamp meter.

One easy question to answer and you are in with a chance.

Only basic electrical circuit knowledge required, sort out the basics and go for it.
Help available for new trainees just pm me.

Good luck.

Mate, you would not believe the size of my brain f@rts sometimes. Just ask my level 2 class, lol... :willy_nilly::6:

I've had a few weeks away from it all - some busy weeks with the uni job and an awesome holiday in Portugal. Time to start getting my head round electrical stuff, and getting back into the swing of things again...

The mv/a/m already factors in the 1.2 correction factor to 70c.

(R1+RN) x Ib X 1.2 will give you the same answer as the above.

Cheers mate, glad i didn't miss anything.

The 1.2 correction factor is something i remember reading on here ages ago but its only just clicked now you have brought it up :icon14:

0.004 coefficient of copper. So 1 at 20c plus 50 x 0.004 = 1.2 to correct it to 70c.

its been a long day, i'll digest that one in the morning!

Check OSG or GN3

Spot on!

I was ever so pleased with myself when I worked out how the mV/A/m tables in BS 7671 related to the R1+R2 tables in the OSG/GN3. Hence this old post.

This is what i was explaining to the 2394/5 class on wednesday night.

It seems a lot of the time served guys had forgotten most of the theory unfortunately.

Careful. They'll get you teaching/tutoring if you pipe up in class with stuff like that! :willy_nilly::aureola:

I may as well be lol. Everything i have been taught i have done already.

I am relying on my books to get me through.

You overestimate me :lol: I haven't a clue. Just asked Richard for a clue now; I'm hoping it'll become obvious when I know how :confused5:

So hows the competition going lads, sorry I've not been as involved as usual just been busy recently.

 

[pennychew]

Going well mate, haven't had much time to get involved myself the last couple of days though. I think I might post up a list of who's got a correct entry in so far if everyone agrees?

I have no objections to this mate.
