Size of flex
Apr 14th, 2005, 11:49pm
 
I intend putting longer 2 core round flex on a couple of my power tools,the heaviest i can get is 0.75 mm ,however this does not seem as thick as what is already fitted.Will this be ok on drills or handplaners upto 800 watts?

Yep, the differences in flex sizes can be difficult to tell as there so close in size, what’s more the PVC can be a different thickness on different cables, but if it's marked 0.75mm on the cable you're good to go.

Do try to keep the flex as short as is possible as this is recommended practice due to tripping hazards and possible damage to cables.

for you're own reference, flexible cables of the following sizes have the following current carrying capacity's..

0.5mm - 3A (690W)
0.75mm - 6A (1,380W)
1mm - 10A (2,300W)
1.25mm - 13A (2,990W)

But these are strictly for short lengths and only for portable appliances, Flex should not be used for doing fixed wiring in the house as it's not designed or suitable for this.

I prefer longer cables actually.  When up a step ladder you're not trying to balance the extension lead drum up there with all the other paraphernalia you need to hammer on a light fitting  Roll Eyes

btw, my Fein Multimaster has the longest lead I've ever seen on a power tool, it's brilliant.  Cheesy

Yikes, you're a clever girl santacruz, I must stick a note to remind people flex is only suitable for portable appliances in general, else there's going to be a rats nest somewhere  Grin
