Cables

Then the need is to look in the tables in the standards applicable to the country of installation. In the UK, it is British Standard 7671.

Cable sizing has been covered in this forum many times. The question identifies a need for the original poster either:

• to become familiar with the local standard through some sort of training, or,
• to hire a qualified electrician locally that can do the assessment on the hirer's behalf, or
• to enter the words 'cable sizing' into the 'Search all of CR4' box on the right of this screen, whereupon the outcome will be one of the two items above.

Do turn off Caps Lock first, though.

CR4 does not offer cable sizing training courses.

All will safely carry 1.5A with no danger of overload.

See manufacturer's catalog or BS7671 with reference to rated voltage,insulation,sheath, armour, ambient temperature,method of laying,soil resistivity,proximity to other cables,thermal insulation etc

Copper or alluminium cable???

Any cable manufacturer's website would have given you this data. Try Fort Gloster Cables or Universal Cables web sites.

just go to the supplier catalog and see the amperage rating of the cables at a given temperature.

Mr. Mahmood,

Just go through the GTP of cables.

No Lyn? Fine......

<sigh> Additionally CR4 is not a homework cheat site. If this is not homework WTF are electrical workers being taught now days that they can find an obscure engineering discussion website on the internet (CR4) but cannot find the information in

- Any decent cable manufacturer's website literature

- A simple internet search

- The general electrical standards they are working to

- A library book on cables

- etc

If this is not homework (or plain general interest) STOP WHAT YOU ARE DOING and get help from someone (not us) as you appear to be in over your head.
