Electrical Cabling Size Table

[Marky]

Hey all,

The engineers at my work know how to calculate the current by dividing the Wattage by the Voltage, however they don't know what cable sizes are required for certain jobs...

So... I need a table which shows you cable size and how many amps it can take to stamp on the wall so they don't have to keep bugging everyone else

Anyone know something like this on the net?

Many thanks,

Marky

Google brings ups loads but I can't be bothered to rehost them

From a quick look over them - They're not what I'm looking for. I need to know how big the cable is. I.e. 6mm cable will be okay for up to 22amps etc.

I was about to say that you need to divide power by voltage (not multiply) to get current but you ninja edited your post.

Haha you almost caught me Had to do the triangle in my head - Shocking, I'm getting rusty already

Guys I'm not looking for the calculation - it really doesn't need to be as complicated as you're making it sound Our engineers rarely fit cable - but when they do they are told the phase (single or three) of the supply and the wattage the equipment will require. From that they need to know what size cable they require for the job. The length of cable they use is usually two meters max.

Oops sorry I missed your reply! I'll have a read of it tomorrow at the office! Thanks a lot
