Hello,

We are currently working on a site in which we are installing a Mitsubishi Electric VRF system, the transmission wiring installed is all 1.5mm2 as specified by the manufacturer, however, at certain points in the system, 0.75mm2 wiring has been installed instead.

I just thought I'd query it with the forum to see if anyone thinks it would be an issue at all. I know various other systems usually specify 0.75mm2 to 1.5mm2 for the transmission wiring. Am I right in saying most transmission wiring will genrally carry 12-24VDC so I would of thought an overheating of cables issue would be well out the question.

Any help would be greatly appreciated

Cheers
