4 Pin 20 Amp "Construction" 3 Phase Industrial Extension Leads
4 Core 20 Amp Construction Extension Leads
The Australian Standard 4 Core 20 Amp Construction Extension Leads for indoor, outdoor and harsh environments.
The “construction” lead has a larger diameter cable and longer maximum allowable length from the outlet to the appliance than heavy-duty 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).
*The for the calculation of the maximum extension cable length the outlet is assumed to be 25m from the distribution board.
The leads have the option of being tested and tagged ready for use before dispatch.
