Answer / aamer

No need for voltmeter. Bigger cables mean higher curent which mean lower voltage (LT).
If you want to check by voltmeeter then there is a spacial HT voltage tester kit assosiated with insulated stick. But becarful this should be done with respect of high voltage clerance distance chart.
