Tesco jump leads - any good?

The message from "Alan Dempster" contains these words:

Really? I'd have thought perhaps 25 square millimeters, but not 25 millimeters squared!

Which side do you connect the blue & white lead to?

Thus spaketh Guy King:

In imperial it would be square something, such as 2 square inches, but metric is always something squared such as 25mm squared.

Maybe they couldn't find the ² - 25mm² means 25mm squared.

The message from "{{{{{Welcome}}}}}" contains these words:

I think you're missing the point.

- which sound nearer the mark.

a 10 mm square is *not* 10 mm². It's 100mm².

Yes. My home-made ones based on the 40mm2 Extra Flexible cable from here:

Either, as long as its same both ends ;-)

I have a feeling that the Tesco leads may be like this.

Here is a picture of some similar-looking leads.

Maybe very good but not wonderfully cheap even though you make them up yourself:

I never said cheap! You'll need 3m of each colour cable as it's supplied per colour....

Having been caught out by cheap 'n' nasty cables in the past I made these up to be beyond anything I was ever likely to need to start [1], and made far longer than standard cables too. Being 40mm2 the voltage drop over the cable length was small enough not to be a problem, but with a smaller guage cable it would have been.

It means 25 square millimetres (also written 25mm^2) - 25mm squared=20 would be 25mm x 25mm =3D 625 square millimeters

He knows that - why are you telling him?

Is it heck as like[1].

If they're anything like any of the other cheap jump leads available, they'll be s**te.

I bought mine for around £15.00 from the local olde worlde motor factors.

They're huge, heavy, have big metal clamps with rubber insulated handles, and I suspect could be used to jumpstart small Wales on a frosty morning. I suspect the chappie in the motor factors has made them himself as they're

My local friendly RAC man lusts after them...

Post corrected.

Ooh look. the same original comment you snipped from my post. And the same explanation I gave, which *you* complained about.

Fancy that!

I didn't snip anything from your post. Nor did I copy anything which=20 you wrote. I replied to {{{{{Welcome}}}}}, you replied to Guy King - do=20 you understand how threading works?

Perfectly thanks. Never mind.

Post re-corrected.
