What wire do I need

[Jamesrst]

Hi I need to Extend this wire it runs from my invertor from my solar panels to the import meter, I would like to know what size it is so I can match it see photo https://drive.google.com/file/d/1nROqYN3V1OENictcbprJv2mfLlDXsn9k/view?usp=drivesdk the wire says 300 / 500 v bs6004 6242y 2x4 + 1.5 not sure what it means for a guess 4mm ? Thanks

Hi, 4x2+1.5mm twin & earth cable is 4mm conductors with 1.5mm earth.

Depending on the distance, you may need 6mm.

"mm" ? I think you'll want "mm²", don't you?

Yes Harald, that is what I mean, but I don’t have that option on my phone

I don't have it on the phone either. Option: mm^2
Cheers,

Depends which country you are in as for example in Australia, requirement for cable to be run inside underground conduit and 450v/750v rated(amongst a raft of other requirements)
