5 Pin 20 Amp "Construction" 3 Phase Extension Leads
20 Amp, five core, 3 Phase, “Construction” Extension Leads.

It is suitable for use on sites that have a few 3 phase outlets, or the lead is connected to a temporary site power board that is a long way from the local distribution board. Where voltage drop is a consideration (either the machine is a considerable distance from the main distribution board or has high starting current).
