Now if we go back to that ridiculous thread about cable size.

If we knew the cable length and the measured voltage at the origin we could work out the volt drop[SUP]1[/SUP] and the resultant load[SUP]2[/SUP].

As I recall it needs a quadratic equation for the two variables [SUP]1[/SUP] & [SUP]2[/SUP].

Forget it! Its 45 years since I last worked this out and it gave me a headache then.

Personally I'd rip the cable out for scrap and run it on a 2.5mm T&E

Yeah some people are just extravagant.

Yup very true, they are clowns alright and we are tradesmen, we have to take it serious, electricity kills people, a leaking pipe will not, nuff said, n it.

...unless of course,it has a U4 at the start of it....:conehead:

Quadratics! Going to get back into that soon.... Just in time for the kids exams.....

No that would overload it.

Not if you follow MIs and fuse everything down!
Oh, Hang on a minute. I've not thought this through properly have I?

The ELFI is 0.4 ohms. It is also protected by a 30mA RCD. Can I leave it on?

Pete, 6/10 for trying but 0 for originality, 0 for thought, 0 for artistic content.
You're going to have to try a bit harder if you want to get a bite mate.

Have fun! I've not used them since college.

More to the point I don't want to use them. Although if I'm really bored one night I may have a go at doing a spreadsheet.

Only if it's feeding the battery charger and light in the garden shed, the heating and extractor fan in the pigeon loft and the PIR controlled security light.

It all sounds a bit fishy to me.
